[Pkg-libvirt-maintainers] Bug#520772: virt-manager: migrate Xen guests fails with python error

[Andreas Unterkircher]

Package: virt-manager
Version: 0.6.1-5~mm.1
Severity: normal


While I can migrate a guest between two Xen hosts with libvirt/virsh
(migrate --live domU xen+tls://...,), virt-manager fails to do so.

When I do a right-click on the guest -> Migrate -> the other node,
virt-manager just prints

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/manager.py", line 1120, in migrate
    self.emit("action-migrate-domain", vm.get_connection().get_uri(), vm.get_uui
d(), host_uri)
UnboundLocalError: local variable 'host_uri' referenced before assignment

The same message get logged to virt-manager.log as well.

Upstream (0.7.0) has some changes around the migrate function. There it might
be fixed.

Cheers,
Andreas

PS: Sorry for the many bugreports :-)
