Doesn't have to be - but it must be *as good*.

Not much IME beats it (except on price[1]). Extremely reliable, hot 
migration of host (OK everything can do that) and hot migration of VM 
storage (not so easy).

Good performance monitoring.

Console access to VMs.

Resource limiting - I have had a very busy VM burn 2000+ IOPS (from a 
budget of about 5000 that the SAN can manage). Legit work - but I could 
quickly impose an IOPS cap on the VM to prevent it mashing the others.

As far as I know, Xen (for example) can't do all of those.

That is what we are currently doing and I agree - clearly the most 
flexible solution. The hard part is that the datacentre we are in may 
not be an option next year and it comes with a 10gig pipe to JANET. It's 
actually the connection that gets infeasibly expensive very quickly.

With caveats about Xen noted (unless that has improved) - thanks, I will 
have a look.

Yes - that (DDOS) is a very good point.
