[libvirt] [PATCH v6 11/13] qemu: Block snapshot operation with RAID
For now we block all snapshot operations with quorum,
because it would require a lot more code,
especially because Qemu doesn't really suport it.
I guess, we can use node-name, and manually snapshot all qcow
from a virStorageSource and use this as a quorum's snapshot,
but libvirt doesn't support node-name, and we don't need
node-name anymore to use a quorum in qemu.
I have some patchs which could partially support quorum snapshot
on my computer, but nothing suitable to be upstream, so I prefer to have
a stable versions of quorum inside libvirt before dealing with
snapshot.
