Hello, openstack developers!

We are using openstack on XCP. And if we tried to snapshot VM with iscsi
volumes attached nova fails with http://paste.openstack.org/show/18205/

I filled a bug report few days ago
https://bugs.launchpad.net/nova/+bug/1005950 , but there is no answer.

Also, as I could see qemu,kvm snapshotting was refactored
https://github.com/openstack/nova/commit/7dbf9c7de23623223ef60c0566d9330797c5f87ein
favor snap ONLY root devices instead of libvirt snapshotting

We could use some small hacks to prevent snapshoting with attached volumes,
but it would be better if xen(xcp) snapshotting will refactored likewise a
libvirt one. Is it possible?
