</div>Well.. we've been using lvm image based virtual machines as resize operations<br>
are simpler.. lvextend, lvreduce, etc. Lvm based virtual machines are also<br>
faster because they don't have the overhead of the dom0 filesystem.<br>
<br>
Using a fileysystem put images has some drawbacks as performance, managment,<br>
etc.<br>
<br>
Snapshots are also easier in lvm (not yet supported in clustered lvm), as well<br>
as mirroring volumes.<br>
<br>
Hope that helps convincing supporting lvm images.. :)<br>
<br>
