Best Linux based hypervisor for a single Windows VM

[lizardking009]

I have a Fedora 12 x64 server running kernel 2.6.34 for the LIO-Target iSCSI target. The hardware is a Xeon X3430 w/8gb RAM and an Areca hardware RAID card. The server is headless and I connect to it with SSH and the onboard IPMI if needed, X is not running and I don't really want to run it. I need to run vCenter 4 somewhere, so I figured this box has the resources to do it.

OS choice for vCenter can be 2003, 2008, or 2008 R2. It makes no difference to me. I need to be able to administer the VM from a Windows box. With my server and requirements in mind, what is the best hypervisor for running Windows on Linux?

Xen and KVM are solid, XenServer is nice and super easy to use with a XenCenter though (windows management interface).

xen

I say kvm since xen is extremely slow to upgrade the kernel and kvm is built in so you can use recent kernels like 2.6.34 instead of having to track down patches.

I second this.
