As I said before, that causes apps to have to do special handling
for iSCSI pools, which is not something we want.
This is not about iSCSI pools, it is about type='lun' devices.
And as I said before, knowing the kind of pool is something you have to
do anyway for type='lun' devices, because they won't work if the
underlying pool is filesystem- or LVM-based.

It should always fail to start the guest if the pool is not started,
regardless of the mode used.
Another point of mode='direct' is that the pool need not be started.
