If you are looking at VMware, ESX(i) is the nicest of the bunch but moderately
expensive for the full version that does clustering and live moves - and you
also need a highly reliable iscsi disk server. But even the free version is
very nice in terms of the management tools, low overhead, and the ability to
overcommit the host's RAM. You could start by building shadow copies of most of
your servers that could be activated as needed, with perhaps a few being live
with application level failover (heartbeat, drbd, database replication, etc.).
ESXi is also a nice lab framework for testing new thing.
