[Pkg-libvirt-maintainers] Bug#574272: libvirt0: libvirt update breaks 'save' command on domain; Error message: "Migration is not active"

[Andreas Bießmann]

Package: libvirt0
Version: 0.7.7-1
Severity: important


Since livirt upgrade to 0.7.7 in my test box the command
'virsh -c qemu:///system save <DOMAIN> /tmp/<DOMAIN>.img' is broken.
The response from virsh is:

---8<---
error: Failed to save domain <DOMAIN> to /tmp/<DOMAIN>.img
error: operation failed: Migration is not active
--->8---

Downgrade to 0.7.6 fix this issue.

We used to backup our VM's in production system with a little script which
relies on this save/restore feature. This is a main feature of libvirt an
should be fixed until squeeze release!

This issue might be in mainline libvirt too but I have not tested this.
There was a major upgrade to kvm driver in libvirt supporting asynchronous jobs
since 0.7.7

Anyone involved in upstream development?

Additional information:
 - we use a kvm virtualisation
 - not tested with other backend

regards
