If they were mandatory, then all the virtual machines would be restarted 
when libvirtd restarts. This is not desired nor needed. When this 
happens, the node is fenced because it is unable to restart VM in 
absence of working libvirtd.

You are right, when the constraint is mandatory, live migration works fine.
