[CentOS-virt] Recommendations, please

[Steve Campbell]

I've finally got a new machine coming that will allow me to play with 
virtualization. What might most of you recommend for the type of 
virtualization software I use. I seem to recall that xen might not be 
the best choice due to it's lack of development. I could be wrong, 
though. For the present time, all of the VMs will be Centos based.

Any opinion will be appreciated.
