virt-manager prevents migration of KVM guest over SSH connection with following error:

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

This is wrong, because I can successfully migrate manually with:

  virsh migrate --live guest qemu+ssh://host2/system

Reproducible: Always

Steps to Reproduce:
1. fire up virt-manager on a host with the guest
2. define connection to a second host using SSH
3. attempt migration of guest to the second host
Actual Results:  
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 556, in migrate_domain
  File "/usr/share/virt-manager/virtManager/domain.py", line 1357, in migrate
    self.vm.migrate(self.connection.vmm, flags, None, dictcon.get_short_hostname(), 0)
  File "/usr/lib64/python2.6/site-packages/libvirt.py", line 378, in migrate
    if ret is None:raise libvirtError('virDomainMigrate() failed', dom=self)
libvirtError: invalid argument in only tcp URIs are supported for KVM migrations

Expected Results:  
Successfull migration of the guest.
Comment 1 Mark McLoughlin 2009-08-18 09:07:33 EDT
What versions of virt-manager, libvirt and qemu-system-86 is this?

Could you include ~/.virt-manager/virt-manager.log? Also, /var/log/libvirt/qemu/$guest.log from both the source and destination hosts?

The error message is coming from the libvirt qemu driver, and it refers not to the qemu+ssh:// URI but the optional <migrateuri> which you're not passing to virsh

It looks to me like virt-manager is passing the destination hostname (i.e. not a URI) as this parameter which is totally bogus
Comment 2 Jan Dvorak 2009-08-19 06:42:03 EDT

libvirt.log contains the usual stuff + only the backtrace above, $guest.log is empty (except for the qemu-kvm... command)

It's very reproducible, you may want to try it yourself.
Comment 3 Cole Robinson 2009-08-31 10:53:06 EDT
We were invoking the migrate command incorrectly in virt-manager 0.7.0. We should just copy the migrate routine out of domain.py in current upstream and backport it to F11.
