7/17    Should I get VMWare Fusion or Parallels 4? I don't want to use
        VirtualBox because it's kind of slow.
        \_ Yes

2/20    Why flash ram will get you into trouble, in the long run:
        This is worse than over-clocking your computer. There's data
        \_ What's your point? That flash supports a fairly limited number of
           write cycles? We knew that already.
           \- I am not the OP but dont think you're inquiry is very
              thoughtful. This may be another case of "physical difference"
              [between rotating mag storage and memory cell storage] cant
              be abstracted away by software emulation" [in this case
              focusing on the write/erase asymmetry]. An older example of
              this with another hyped technology was ATM emulation of
              Ethernet and the problem of doing broadcasts.

12/2    1000 lines about Vmware.  have you even tried to install
        Vmware 2.0?
        \_ if it's about messing around with virtualization at home, I've done
           quite a bit of tinkering already with VMWare, VirtualBox, etc.

11/29   I'm experimenting with virtualization, and as a poor college student
        I'm wondering what the best alternatives for virtualization are, and
        how best to cut my teeth on messing with non-linux platforms (or I
        guess interesting stuff on Linux would work too). Right now I've got
        FreeBSD7 running on KVM on my home computer (on a Core 2 Quad), and am
        somewhat at a loss as to how to use it. (More details: bridged
        networking, disk is a 8GB partition software raid1'ed over 3 disks).
        In any case, KVM seems to just 'work', but as the CSUA is planning to
        offer VMs soon, I'd like to know if there are better alternatives,
        particularly considering that when I put my computer to sleep without
        shutting down the guest OS, the computer wouldn't start back up, I had
        to cold-boot, and the disk image got corrupted. From what I hear,
        VMWare's offering is solid, but the useful administration software is
        thousands of dollars. Ideally, free software or something sustainable
        without repeated donations of software, and easy to administrate would
        be best. Does anyone have suggestions? --toulouse
        \_ At my job, we use Vmware 2.0.  it is free.  i run vms.  there
           are graphical admin tools.  I could buy Vmware ESX, which gets
           me I guess better admin tools, better performance vmotion and fail
        \_ Someone here works at VMWare and was recruiting 2 years ago.
           Calling the VMWare guy! We need a free educational license!
           Oh well, he's probably not going to respond until Monday.
           Us old farts have kids and family things to go on weekends.
           Oh, try this. And yes we use VMWare in our company and it
           is really great. You can get snapshots of the machine, run
           multiple instances on a single machine (since most machines
           are underutilized). Our production servers are also in
           VMWare for superior bug isolation and debuggability:
           \_ What, you mean CSUA alums have lives? Unthinkable! --toulouse
           \_ Isn't VMWare Server free?  That's what we use in our company.
              --- !OP
              \_ I don't recall the details, but while the server itself is
                 free, I think the administration interface is expensive.
                 Feel free to correct me on this. --toulouse
        \_ Here's the deal.  Vmware has two products.  The Free Version
           (Vmware 2.0) , and Vmware Server ESX ( not free. lots of $$$$ ).
           ESX is a different codebase than Vmware 2.0 free.  With ESX,
           you get better performance, better GUI tools, failover capability,
           and the ability to magically move your VMs from machine to machine.\
           freely available Vmware 2.0 has a gui too.

              \_ dude are you running a root name server?  Vmware 2.0 is
                 just fine.
                 \_ doesn't mean ESX wouldn't be better ;). Ease of admin is a
                    real concern for us, and besides, if the software is
                    satisfactory, we might even virtualize soda itself. Given
                    time, if we got another server with virtualization
                    extensions, failover would be a large win. As you may have
                    noticed from recent downtime, Keg's been on the fritz
                    lately, so uptime's been on our minds. Without failover,
                    we're back to square one re: evaluating KVM vs VMWare vs
                    others, hence this thread. Besides, there's an argument to
                    be made that if we have experience managing the good stuff
                    here in college it'll be what we're qualified to manage once
                    we strike out in the real world, and/or the software that we
                    recommend to our superiors should we get relevant jobs
                    (which, arguably, a few of us will). --toulouse

                       There are plenty of cheapass companies out there running
                    \_ You know, when I was a poor college student, I
                       wasn't very picky. Seriously, the two may have
                       different features that you'd need in the enterprise
                       environment, but are you running an enterprise?
                       \_ Well, I'm not picky wrt/ using what works for me
                          (which, as I mentioned before, is KVM), but I
                          want the CSUA to be a bit more ambitious in its
                          endeavors, and as they say, shoot high, aim low
                          (is that the right saying?). Plus, there's the
                          fact that our vp is not paid, so minimizing the
                          addition to his workload while offering more
                          students to members is also a factor. In any
                          case, I think it'd be prudent for us to see if a
                          software donation is feasible, and if not, what
                          our other options are then. This is something
                          that can wait a bit, as we're waiting on those
                          core i7's. --toulouse

                          \_ well if this is about the CSUA rather than
                             personal edification, how about first dealing
                             with the frequent crashes/outages of soda ...
                             or is this an attempt to do so? [this seems
                             odd to me, but whatever]. second, to abuse
                             a quote a bit, "software is the continuation of
                             policy by other means" ... "what [csua] problem
                             are you trying to solve" [via this software, via
                             donation campaign/new hardware etc]. BTW, with
                             regard to giving csua people experience with
                             expensive tools, i actually think part of the
                             reason a lot of ex-csua people have been
                             successful systems people is they resorted
                             to hacking togethe things and thus understanding
                             how they work under the hood, rather than
                             throwing money at the problem [hardware and
                             softwarewise] ... i'm not saying you should say
                             solve all problems that way ... like if you need
                             disk space today, just go buy a cheap disk
                             rather than scrounging, but just the observation
                             in the past, some of this hacking to debug
                             something or getting it to work (and much of
                             this was pre-google) served people well.
                             \_ Yep, real learning comes as part of the
                                struggle. In some sense, it would be better
                                for students not to primarily have experience
                                with enterprise software packages since
                                these are made "easy to use" for the corporate
                                drones who wouldn't survive if they had to
                                have any real degree of understanding of how
                                the system actually works.
                             \_ Well, the learning I was looking for when
                                putting the idea forward (since I suggested
                                it) was geared towards people exposing
                                themselves to different OS'es and playing with
                                root in a sandbox. This is the problem I want
                                to solve, not training people in enterprise
                                applications. Also, soda hasn't been crashing
                                -- it's been keg, which serves our LDAP, that
                                (as I said before) has been on the fritz. If
                                keg goes down, then logging in does not work.
                                Politburo intends to buy a new server for
                                this; however since the Core i7 is coming out
                                we don't want a purchase now to be obsolete
                                upon arrival. We have the opportunity now to
                                solve two problems at once: allow interested
                                members access to their own personal VMs, and
                                increase stability of our servers. We can most
                                definitely do without failover, but then the
                                uptime problem isn't as completely solved.
                                The idea of getting students experienced in
                                adminning VMWare may be of low priority for
                                the CSUA as a whole; on the other hand, it is
                                (IMO) the strongest argument to be made to
                                In summary (and in my opinion) -- high
                                priorities are increasing uptime and developing
                                skills with adminning systems.
                                low priorities are developing VMWare admin
                                skills and...well, steven should be coming on

           Re VMWare - Fusion for OSX is very nice and quite affordable (I've
           seen it on sale recently for as little as $30). It has GUI admin
           tools and the unified mode makes using windows apps almost like
           using native OSX apps.
           I'm currently using Fusion to run WinXP and Ubuntu and have used
           it in the past to run Solaris x86 and FreeBSD as well. I usually
           run XP and OSX concurrently and haven't ever had any problems with
           the XP VM getting corrupted when I sleep my iMac. If you have a Mac

                 wondering ... how best to cut my teeth on messing with non-
                 linux platforms"). If he has a mac, Fusion is a good way to
                 accomplish this - it can run Solaris, Linux, *BSD, Windows,
                 &c. and will help him get a feel for those systems. Virtual
                 Box, while not as nice as Fusion (at least on Mac), is a
                 free way to accomplish the same.
              \_ These are two different objectives.  I'm talking about setting
                 up VMs as a service for CSUA so we can consolidate our machines
                 while maintaining some sort of security and OS diversity (linux
                 + BSD at least)  If toulouse wants to learn about

        \_ Hey guys - Steven here
           Thought I'd weigh in on the situation.  The recent outages have
           indeed been because Keg has been crashing (as presumably toulosue
           pointed out) and I'm fairly sure it's a hardware issue.  We're
           simply running too much IO through the (decently old) system
           and parts of it have already failed (we've lost one of the
           ethernet controllers already) so I'm willing to blame the system
           instead of the software.  That said, we're hoping to buy a massively
           cool system when Core i7 Xeons come out (thinking 16+ cores).  At
           that point it seems reasonable to look at virtualization.  I've
           used Fusion and Virtualbox in the past, so I'm not new to it
           by any means - but one of the requirements is that it's easy to
           admin/use.  The issue here is the host OS - I'd like to use ZFS for
           the disk array we'd need to have to back all this.  Linux doesn't
           seem to have a very good filesystem for this sort of thing - ext4
           isn't stable, btrfs is still even further off, ext3/LVM is pretty
           hacky, JFS/XFS really really need battery backups to not lose data,
           and reiserfs's future is very unstable.
           ZFS offers ZVOLs which seem to be perfect for giving out virtual
           partitions.  Right now we have Soda mounting off of Keg via NFS
           which as you may have noticed is a serious performance and stability
           problem, so I'd prefer not to go with NFS again.  The network FSes
           out there all seem to suck in one way or another, so local storage
           (especially for something like this) seems to be a must.
           Since that limits us to using FreeBSD or OpenSolaris as a host OS
                                         \_ or OSX, see:
                                         [ - zfs(8)]

                                         Mac Pro/XServe :(
           (unless Linux ends up having a decent fs by the time we actually
           get this running).  Virtualbox doesn't seem to work well on FreeBSD
           (as in not at all) and Xen seems to not play nicely with either
           BSD or Solaris as a dom0.  VMWare won't run on BSD either - not
           sure about Solaris, which is why I was looking at ESX.  The problem
           with ESX is that it runs on only about 3 supported hardware
           configurations which are pretty hard to build on our budget.
           I'll hang around and maybe get into this whole motd thing ;)
           \_ Virtual Box on OpenSolaris w/ ZFS sounds like it would probably
              work.  I used to know some OpenSolaris people when I was at sun,
              and could probably put you in touch with them if you run into

6/11    To the person who asked about VirtualBox...

6/10    Is there a handy guide to virtualizing an already running
        physical linux box into an instance of Vmware?
        \_ this probably isn't the "right" way, but I have many times
        just run rsync. ("rsync -vpa root@oldbox:/ /")  on a fresh virtual
        image.  Just make sure the partitions are the same on the virt disk
        as on the real disk and if you are using a new udev, kill the info
        in /etc/udev/rules.d/z25_persistent-net.rules before rebooting the
        virt).  I have not had any problems doing this.

        files, copy/paste, all of that crap
        \_ Cool, I was thinking of looking into this soon.  How well does
           it work?  Can I run most windows programs pretty well?  ActiveX?
            \_ You might be confusing running a vm with 'wine' . -op
           \_ It runs all your windows programs... if your guest OS is windows.
              \_ Sure, but there could theoretically be issues with drivers.
                 Say the video drivers don't interface properly so you can't
                 play 3D games.  Or performance is too poor.
                 \_ Running your 3D games in a VM will never work very well.
        \_ How does it compare to vmware workstation?
              \_ There we go:  3D acceleration:          no
               \_ The big VM players are working hard at getting 3D acc
                  support.  It's gonna happen sooner or later.  5 years ago
                  VM for anything real was a bit of a crapshoot.

12/3    Has anyone seen this VMware problem before?  When I have one or two
        VM session running, Task Manager on my host machine shows that the
        vmware-vmx.exe processes uses 0% CPU time when the VMs are idle.
        However, when I have more sesssions (maybe 4 or more) running, Task
        Manager shows that each of the vmware-vmx.exe processes is using
        10-20% CPU time even though all the VMs are idle.  This eats up CPU
        cycles from my other processes.  I'm using VMware Server 1.0.3.  I
        have a HyperThread CPU and the "Number of processors" setting for my
        VMs are set to 2.  Thx.
        \_ What do you think of VMWare in general? We are evaluating it now
           for possible purchase.
           \_ What are you going to use it for?
              \_ Almost everything.  Production servers, dev and test
                 environment. Probably not for the database servers though.
                 Does that answer your question?
                 \_ No. It doesn't. What are you hoping to gain by using
                    \_ Server consolidation, better ability to manage
                       dev and test environments, hopefully a better DR plan.
                       \_ Sounds like VMware might work for you then. I've
                          used VMware since version 3 and I've been pretty
                          happy with it. I don't know if I'd transition
                          all of my hosts to VMs just yet, but it excels
                          in meeting the needs you have.

           find a better explanation anywhere else.  Kudos to their doc
           writers on that one.
        \_ Virtual memory is not an issue.  As to the rest, unless you are
           doing stuff where getting about 1 percent more out of your cpu
           matters, don't worry about it.  Hyperthreading has a bit of
           performance hit in most cases but makes up for it by making
           the computer much more responsive at high load.  In a gui environment
           this makes you computer feel zippier and is worth the performance
           \_ Actually, it makes the computer less responsive under a high
              load. Why? Because the CPU is trying to execute more
              processes than it has processors. Try this experiment: Run
              three jobs with a nice level of 20. Then run one interactive
              job. See how (un)responsive it is? Now turn off HT and
              repeat the experiment. I guarantee you it will be more
              responsive in the latter case.

1/10    VMWare GSX is most similar to VMWare Workstation. GSX allows the

        machines use a different file format than Workstation / GSX. Also,
        installation and administration of VMs is always done via web browser
        or remote client, and not directly at the server's interface. The file

                    \_ Uh, I thought I made it clear already that you can
                       try setting the VM to use host-only or NAT networking.
                       You still haven't said whether your host OS uses DHCP
                       or not.
                        \_ Yes, host OS uses DHCP, what difference is that
                           gonna make? If it's not DHCP it renders my laptop
                           portability to "pain in the ass to reconfig"
                           \_ Well, I don't know what Windows does when it
                              can't obtain a DHCP address, but it doesn't
                              surprise me that it would suddenly become
                              unaddressable.  Anyway, you always could
                              try adding a second virtual NIC to your VM
                              that uses host-only networking.  I'm not sure
                              if that would work; I've never been in your
                              situation.  If not, then ask on VMware's
                              support forums.

        \_ Yes.  I like it a lot. --jameslin
        \_ Is VMWare related to the "VM" OS on IBM mainframes?
           \_ IBM mainframes did do virtualization back in the day, but
              otherwise, no.
              \_ they still do today; it's the basis of their linux
                 server consolidation story.
           \_ the IBM VM is more like Zen, in that the OS is written to
              an appropriate virtual machine rather than trying to virtualize
              a hardware platform not designed for it.  they also have
              more virtualizable hardware because of this legacy

1/28    Who here works at VMWare? I have a suggestion for you so that maybe
        you can talk to a marketing dude or something. I think VMWare is one
        of the coolest products out there. How about this for marketing.
        Give free copies to academia, they really need it for say, OS projects
        and what not. Also, give lots of academic discount to students
        since many of them are Linux/Win dual boot users, and since quite a
        few of them are kernel hackers it'd surely suck them into using your
        products. Once you get the kids addicted, they'll keep coming back.
        Mr. Evil M$ Gates understood this decades ago and gave free copies
        of WinCrap stuff to academia, and look how well he's doing.
        \_ Giving software to academia is not free.  The tax break can be
           extremely valueble.  I've seen some pretty shady stuff with
           software donations.  Does a company really deserve a 2 million
           dollar tax writeoff for donating software that isn't really needed?
           Maybe, but it's definitely not "free."
        \_ Doesn't VMware have academic pricing?
        \_ That's like the M$'s strategy of settling the anti-trust lawsuits.
        \_ VMware has been profitable for quite some time.  I don't think
           they need your help.
           \_ cool because I really enjoy my free warez copy and I love the
              fact that it's so easy to get serial numbers on the internet
              \_ Do VMWare employees have to pay for it?

1/13    VMware performance tuning *experts*, I have a question for you.
        Suppose you don't pre-allocate entire 80G of HD during VMware
        configuration. You have an option of limiting file sizes to 2G
        or have a file that can grow up to 80G. What are some
        advantages/disadvantages of limiting VMware file sizes to 2G?
        Say you have one big file that eventually grows close to 80G,
        wouldn't it be hard to defragment it on the host machine? The
        advantage of 1 big contiguous file I suppose is performance, but
        suppose you don't have enough space to defrag it, then wouldn't
        that option be useless in the first place?

1/10    VMware question for VMware gurus only. I've installed a WinXPsp1
        on top of WinXPsp2. How do you do the followings:
        1) transfer data between the two machines? I've tried mounting
           raw partition from WinXPsp1 but when I disable write, it
           doesn't boot up anymore (WinXP insists on writing)
        2) communicate between the two machines? I can ping WinXPsp1
           from WinXPsp2, but not the other way around.
        3) Say I install VNC on WinXPsp1, how can I make it so that
           VNC ports go directly to it, instead of the host machine?
        Thanks for any help.
        \_ What do you mean 'on top of'? You are running WinXPsp2 natively
           and WinXPsp1 in the VM?

12/21   What are some core differences between a simulator, an emulator, and
        a virtual machine?
        \_ Simulator:  Model the whole thing by itself; collect results.
           Emulator:  Model one part; hook it up to something else.
             Or, run one OS on another OS.
           Virtual machine:  A computer inside a computer.
             Or, a VM like the Java VM.
        \_ Simulator: Models something by mimicry.
           Emulator: Interprets instructions for one architecture to another.
           Virtual machine: A pretty generic term.  There's VM in the sense
             of Java VMs (which represents a virtual hardware architecture)
             or in the VMware sense, in which most instructions aren't
           \_ so the Crusoe chip (on-demand translation of x86 instruction set
              to another) is... emulation? What about VMWare, is that also
              emulation? What about simulators, what are some well known and
              commonly used simulators out there? Does VirtualPC (for Macs)
              count as simulator because you're not doing emulation?
              \_ VMware is partly emulation (for the virtual devices) but
                 for the most part is virtualization.  VirtualPC for Macs is
                 an emulator; it's interpreting x86 binaries.  Won't comment
                 on the Crusoe.
        \_ What's the context?
        \_ In some contexts, a simulator processes the simulation of an actual
           design, while an emulator accomplishes the same result at a higher
           level. A VM is a software computer environment for a program (a
           computer implemented as a program that runs on another computer).

        They get slightly different results. What's the best way to figure
        out why this would be?  Perhaps a way to capture the request?
        \_ Maybe you're just hitting different google mirrors, and their
           indices aren't quite in sync?  You could test this by using an
           explicit IP address like instead of "".
        \_ netcat is good for this.  Use 'netcat -L <DEAD><DEAD>:10070
         -p 8000 -o logfile' listens at port 8000 on the local machine, logs
         to the file "logfile", and forwards the result to athos port 10070.
        \_ Does Google incorporate randomness in its search result when, say,
           there's a tie in relevancy?
        \_ the above will do the net capture but i think the answer lies more
           in how google works than your browser.  packet captures will only
           tell you what you already know: you're getting difference responses
           back from google.

            \_ on what type/speed computer? is "dirt slow" slower than

               to I need to buy to have windows95 running inside vmware
               seem as fast as a pentium 133?
        \_ I thought it was a pain in the ass.  With 5 computers at my desk
           it was easier to just install whatever I wanted on whatever.
                \_ do you jest? How big a hassle is it to have 5 computers

           use the non-persistent disk option and leave edited files in linux

           because you discard the changes from 98% of sessions while friends
           running it native have to reinstall periodically for stability.

        \_ Vmware pretty much just sucks.  I've wasted more time trying to get
           various OS's installed through Vmware under various other OS's than
           the end result could possibly ever be worth.  My time is worth more
           than a little desk or server room space and some old hardware.  I
           like the concept but in practice it just hasn't panned out.

              on a Linux vmware host multiple times with support fo things like
              NAT, file sharing, sound and other hardware support and had no
              problems with it. Try again.
                        \_ VMWare sucks if the guest OS or the host OS is
                           not Linsux or Winblows. (Basically VMWare sucks

                           a real OS)
                           \_ I'm sure that using the terms "Linsux" and
                              "Winblows" makes you look knowledgeable.

6/20    I have an OS question.  Most programs make use of shared
        libraries and use a dynamic link loader to relocate branch
        targets at run-time.  The problem is that if you have
        multiple copies of, say, emacs running under their own
        user space wouldn't those relocated addresses (either relative
        or absolute) conflict under each process?  For example, if
        multiple programs were using OpenGL they would create virtual
        memory entries for in their own process space. The
        location of libGL within this process differs from program to
        program so if libGL calls the dynamic link loader will
        place that library in a different location for each process
        and the branch targets under one process won't correspond to
        those of the other.
        \_ The shared bits are mapped to the same virtual addresses in
           each address space.
        \_ Not sure what you're asking.  But only the text portion of
           the shared lib is shared amongst the different processes.  All
           processes that need to use have addresses that point to
           just one copy of the text portion of  It's the OS's
           job to keep the program counter and the VM straight.  Why would
           there be any conflict?
           \_ That's the problem. If you only have one copy of
              in memory there would be a conflict in the outgoing branches
              from libGL.  For example, if we were calling glVertex
              within libGl. That function would have a jump an link
              to another absolute address to the libm math library. The
              dynamic link loader is responsible for resolving the branch
              addresses.  The problem is that if one user was running
              Quake while another person was  running Doom or something
              like that then the jump target addresses would be different.
              Let's just say, for example, that glVertex called the pow
              Quake                             Doom
              -----                             ----

              0x00003fff end of quake           0x00001fff end of doom
              0x00004000 libGL                  0x00002000 libGL
              0x00005000 libm                   0x00003000 libm
              0x00005040  pow()                 0x00003040  pow()
              If we were to have a jump and link to the pow() function
              then the addresses would be different in both copies of
