migration error - "only tcp uris are supported for kvm/qemu migrations"

[Eugene Oden]

Binary package hint: virt-manager

ubuntu 9.10

relevant package versions:
virt-manager in karmic (0.7.0-3ubuntu1)
qemu/kvm - kernel linux-image-2.6.31-16-server (2.6.31-16.53)
libvirt (0.7.0-1ubuntu13.1)

i'm able to migrate a virtual machine successfully from one host to another using virsh but it fails with virt-manager.

virsh command which succeeds:

   virsh migrate --live <vm name> qemu+ssh://<host>/system

error message which pops up in virt-manager doing the same migration:

Error migrating domain: invalid argument in only
tcp URIs are supported for KVM/QEMU migrations

Details:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 556, in migrate_domain
    vm.migrate(destconn)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1342, in migrate
    self.vm.migrate(self.connection.vmm, flags, None, dictcon.get_short_hostname(), 0)
  File "/usr/lib/python2.6/dist-packages/libvirt.py", line 384, in migrate
    if ret is None:raise libvirtError('virDomainMigrate() failed', dom=self)
libvirtError: invalid argument in only tcp URIs are supported for KVM/QEMU migrations

appears to be similar to the following redhat/fedora issue:

Thanks for reporting this issue. This should now be fixed in the version of virt-manager that is currently in Lucid. Closing this bug.
