8/31    is this cooler than say kickstart or FAI or whatever
        the current cool way to admin 10000 machines is?:
        \_ This seems to be focused on managing Xen VMs and require
           the host to have Xen already installed.  I'm still a fan
           of cfengine, though it won't do the initial install.  But
           I have setup kickstart to just install cfengine at the end
           of the install and have cfengine take care of most of the
           \_ Is it a lot of overhead to have Xen running on every machine?
           \_ Why not use System Imager?
              \_ System Imager, as it was last time I looked, is fine if
                 you're managing bunch of machines with *identical*
                 configurations.  cfengine is more flexible and can work
                 across multiple platforms as well.  Also changing a
                 configuration doesn't involve re-imaging the whole machine.
                 \_ System Imager is more flexible than that. You can
                    propagate just the changes. I much prefer SI to
                    Kickstart. If you want to use cfEngine on top of that
                    then fine, but cfEngine solves a (mostly) different

vylavera What is Ganeti Ganeti is a virtual server management software tool built on top of Xen virtual machine monitor and other Open Source software. However, Ganeti requires pre-installed virtualization software on your servers in order to function. Once installed, the tool will take over the management part of the virtual instances (Xen DomU), eg disk creation management, operating system installation for these instances (in co-operation with OS-specific install scripts), and startup, shutdown, failover between physical systems. It has been designed to facilitate cluster management of virtual servers and to provide fast and simple recovery after physical failures using commodity hardware.
