[libvirt-users] Deploying libvirt with live migration

[David Ehle]

Even if your not sharing /etc/libvirt, if you have migrated at least once, 
both systems see the VM's as available for starting/running so just not 
sharing /etc/libvirt is not a solution to the problem/concern...

Ideally if you try to start a VM that is already running on a different 
host it should balk and you should get an (overridable) warning. (IMHO)
