Re: [Xen-devel] Xen and VMware

["B.G. Bruce" <bgb@xxxxxxxxx>]

Actually, the biggest appeal of vmware is being able to run windows in a
vm.  Most organizations don't really care what is underlying, but it's
the ability to snapshot and restore a virtual machine to a known working
condition (particularly with windows) that appeals.  The faster this
restore happens, the better.  They want the ability to immediately back
out a hotfix or service pack (or any other software upgrade or config.
change) that is causing issues and know that "ALL" traces of the
offending change have been removed - immediately.  No fussing around
with regedit or dll version skew.  This is especially true with terminal
servers.  If you have your corporate desktop sitting on a terminal
server (say 250-500) users and someone infects the box with a virus or
spyware, the faster you can get the box back to a pristine working
condition, the more of a hero you look.  It's the same reason large
corporations look to ghost for their desktop builds.
