I believe KVM was introduced in RHEL5.4, so I presume CentOS5.5 have a
working KVM support as well, in addition to Xen.  Of course, it will be
even better with CentOS6.

For the impatient souls, ScientificLinux 6.0 is released - even though,
discussions lately in this list raises some concerns regarding how good the
binary compatibility is in SL6, compared to CentOS6.

This makes me wondering how well it would go to migrate from SL6 to CentOS
6, if all KVM guests are on dedicated/separate LVM volumes and that you
take a backup of /etc/libvirt.  So when CentOS6 is released, scratch SL6
and install CentOS6, put back the SL6 libvirt configs ... would there be
any issues in such an approach?  And what about other KVM based host OSes?
