[libvirt] New VM Snapshot API Not working

All, Ok, I got it working..... Problem was that I didnt include xen option for configure step. But looks like Xen Hypervisor does not have support of Snapshot. :( I guess I have to fall back to save and restore method... Sorry for the noise.

Ah, I see that you figured out the problem. OK. There is still a bug in that you should not have seen the "remote marshalling" error; we'll have to track that down. And as you found out, we don't have support for snapshots in the Xen hypervisor driver. If Xen itself supports snapshots (does it?), then patches to implement this are welcome. -- Chris Lalancette

The schema tests probably failed because you don't have xmllint installed.
After I started create some snapshot, I am getting some remote error:
root@hcl:~# xm li Name ID Mem VCPUs State Time(s) Domain-0 0 622 2 r----- 1755.3 Test 3 256 1 -b---- 4.4 root@hcl:~# virsh snapshot-create 3 error: unmarshalling remote_error
Ah. We don't support snapshots for Xen, though this is not the error you should have seen. You should have seen "this hypervisor doesn't support virDomainSnapshotCreateXML", or something like that. I'll take a look at it and see if I can reproduce. -- Chris Lalancette
