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?

9/21    are you guys really all using win7 in some way now?
        \_ Yes.  In my company, we have upgraded all our machines for
           development, QA and other office use (HR, Finance, Receptions, etc.)
           from WinXP to Win7 a few months ago.  Our products now primarily
           support Win7/Win2008 and secondarily support WinXP/Win2003.
           \_ Any weird gotchas support-wise?

8/3     VMWare + Windows XP + Validation question. I need to test stuff with
        Service Pack 3 installed. I have a valid key that I own (yeah yeah I
        actually *bought* a copy, please don't flame me for supporting evil
        M$). Is it possible to register the key once, and then duplicate it
        for testing purposes?  Will Windows or Microsoft detect copies and
        disable the rest the copies?

7/28    Does it make sense to defragment disks on VMWare? My 80GB disk
        on VMWare isn't really using 80GB, it just uses what it needs.
        Will defragment do anything to it?
        \_ If you want to speed up disk operation in your VM, it's best to
           defragment the disks in your VM, then defragment the disk on your
           host machine where the VM files are.

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

7/17    -rw-r--r--@
        What does the "at sign" mean? This is on Mac OS. VMWare disk file.
        \_ The file has metadata attributes
           \_ How do I add/delete attributes to files? What about
              -rw-r--r--+ <-- what is the "+" sign? Also how do you make
              tar preserve these attributes?

5/2     why would my php application chew up 20-30 percent of my CPU when
        run on a real machine, but will consitently take up 60-70 percent
        of CPU when run in a vmware vm ?
        \_ the real CPU has more capacity.
           \_ Yes, did you allocate all of your CPU to the VM? Maybe you only
              gave it one CPU or something like that.
