CentOS virt - Jun 2011 - Recommendations, please

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.

I presume this means the cpu has virtualization extensions.

Wait for CentOS6 (scheduled to be available early next week) and use KVM.

Xen is very actively developed upstream at xen.org,
and also the bits needed to support Xen dom0 in Linux 
were recently merged to upstream kernel.org Linux kernel!

http://blog.xen.org/index.php/2011/06/14/linux-3-0-how-did-we-get-initial-domain-dom0-support-there/

The problem with RHEL6/CentOS6 is that Redhat bought
Qumranet (the KVM company) and decided to only ship
KVM host support in RHEL6. 

RHEL6/CentOS6 runs as Xen VM though, so you can use
RHEL5/CentOS5 Xen host (dom0) and run EL6 VMs on it.
