The way that oVirt manage storage domains accessed via FC is very

There is separate logical volume for each virtual disk. But I think that
logical volume at the same time could be "touched" only by one host. Is
it possible that two host access read/write the same logical volume and
there is no data corruption?
hence a shared disk over block storage using LVM must be pre-allocated,
so no LV changes (lv extend) would be needed.
(also, it cannot have snapshots, since it would become qcow)
