Yes, KVM supports both migration & live migration and with KVM-8* and  
libvirt 0.6.4 you can use "virsh migrate --live" to move running  
guests between nodes (live migrate). This fact is reflected in the  
upstream (git repo) version of the vm.sh resource script, but it seems  
like something - rgmanager itself? - is blocking it from even trying.
