[Users] Problems with migration on a VM and not detected by gui

Hi,

Can you please open a bug about KeyError: 'path'?

What error did you get while trying to connect with console (vnc)?
Did you try changing it to spice and see what happens?

Btw, I can see on the dest host this error (on createVm?):
Thread-57::ERROR::2014-02-04 13:47:57,247::vm::4911::vm.Vm::(_updateDevicesDomxmlCache) vmId=`3b995efa-d334-4794-8da7-7a30a7a06664`::Alias not found for device type redir during migration at destination host
