[libvirt] [PATCH v6 11/11] quorum: Block snapshot operation with RAID
For now we block all snapshot operations with quorum, because it would require
a lot more code, espacially because Qemu doesn't really suport it.
I guess, we can use node-name, and manually snapshoot 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 actually 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 dealling with
snapshot.
