Which VM architecture to use... Xen, KVM, VirtualBox : linux

Which VM architecture to use... Xen, KVM, VirtualBox : linux: Use KVM with http://libvirt.org/ and optionally http://virt-manager.et.redhat.com/. I'm using KVM-83 on a 2.6.18 kernel (CentOS 5.5) and it's running stable since months.

RedHat removed Xen in there latest RHEL release and I think Novell will remove Xen in SLES 12, too.

If you want to use VirtualBox take a look at the latest release 4.0 (22. december 2010).
