This is using an AIO configuration in a lab, no chance of a migration =
storm. I=92m just looking for an easy way to move a VM around if I need =
to. 1GB ethernet is getting mighty slow these days, and any other =
shared storage is horribly expensive for a consultant=92s home lab. 10GB =
NIC cards are becoming affordable, but the switches, not so much.

Creating storage domain per vm is not a good idea.

The system is expecting all storage domain to be accessible by all =
hosts. So
if you have multiple storage domains and one become inaccessible, a =

may become non-operational, which will cause migration storm from
this =
host
to other hosts. Basically, the more storage domains you have, your =
system
is more fragile.

Create new storage domains only when you must (e.g. separating testing =
and
production environments). For importing and exporting vms, you can
use =
the
export domain.
