one big issue that has kept me from switching from xen to kvm is that
the default init scripts for kvm don't have suspend/resume for guests
when the host os is rebooted. it doesn't even do a shutdown of the
guests, it just kills them.  also, i haven't looked into whether you can
limit cpu/network usage easily with kvm as you can with xen.  hopefully
some of these issues are fixed in the rhel6 kvm system.
