That sounds interesting and very similar to what we hope to achieve using OpenNebula and a central storage server (as I've posted a few hours ago, not realising this thread here is very similar in nature). > We developed a custom TM driver for this, because this approach makes > live migration trickier, since just before live migration the target > host needs to log in to the iSCSI target hosting the disks of the > vm, and this is something ONE can't do, so we used libvirt hooks to > do this -- works like a charm.

Would you care to go into a little detail regarding your custom TM driver? Maybe even post the sources? I'd be very interested in learning more about your approach to this. Thanks!
