remove this snapshots so when<br>
I attach this volume to new ovirt 4.2 and import all vm at the

Before

everything, I
detach the
storage data
domani (FC)
with the
virtual
machines and
reimported it
to the new 4.2
and all went
well. In<br>
this domain
there were
virtual
machines with
and without
snapshots.<br>
<br>
Now I have two
problems. The
first is that
if I try to
