hence a shared disk over block storage using LVM must be
pre-allocated, so no LV changes (lv extend) would be needed.
By using
"pre-allocated" here, even for qcow on KVM? If it is
pre-allocated, there is no benefit to use qcow.
(also, it cannot have snapshots, since it would become qcow)
Why it can not have snapshots? I think qcow on the block device can also
have snapshots.
