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.
