sanlockd with libvirt, workarounds?

[edward.flick]

Hello everybody,
I submitted the bug, 
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1263162 . At the 
request of Serge Hallyn I am inquiring about how anybody is actually 
getting things done safely with libvirt and shared storage? I see no 
current working solution to prevent accidentally starting multiple 
instances accessing the same shared storage. Any ideas?
