Xen is most certainly an alternative to vmware.... depending on how you use vmware. At Ticketmaster, we do a lot of development on devel "clusters" made up of a bunch of vmware esx servers running Linux as the client OS. This allows us to have only a few beefy boxes but (roughly) as many virtual systems as we need. Xen could work very well in this role. Now Xen does have some drawbacks compared to vmware. Some of them are: o Doesn't play well with NPTL/TLS without a performance hit. This may require modifying the host and client glibc... not always a pleasant task o No capability for snapshots o Missing most if not all of the "enterprise" management features of the vmware server products o Can't run Windows o Installing a Linux OS that doesn't directly support Xen can be a pain The big advantages, of course, are that it's very fast, doesn't use as many resources as vmware, and it's free. I base all this mostly on articles I've read on Xen as I've been following it relatively closely for awhile. I do have a Xen installation with SuSE/SuSE (*very* easy to install) but haven't done more than just play around with it.
