although i was looking for the simplest way to do this, as i stated in the other post, ease of use isn't the end and be all.  if a given implementation is a little more difficult but works well once it's configured, imho it's worth learning and committing to.  if it's a pita and a poor implementation, that's a different story though.  i'm not sure you're saying that xen is the latter, just that you're going to have to dig into some manuals.

the thing i worry about with vmware server is that i believe it's outside of centos' yum and proprietary which i fear will relate to some kind of dependency purgatory or compatibility issues at some point.  also, i wonder about features.  i think different versions or feature implementations of vmware server are commercial, depending on what you need. i'd like to go down a path where i don't get roped into buying something down the road.

is it generally easy to migrate guests from different implementations these days, just in case you decide to change paths in the future?  you'd obviously have reconfigure the networking, but i'm asking more about migrating the underlying disk images / partitions to a new scheme.

sean what virtual server technology do you use mostly?
