I have a remote machine running libvirtd which I used to connect to with
virt-manager over SSH.  Since upgrading virt-manager recently on Factory, it is
no longer able to connect to the remote machine.  Instead I get the following
message:

Error polling connection 'qemu+ssh://root@192.168.1.172/system': 0

Details:

Error polling connection 'qemu+ssh://root@192.168.1.172/system': 0
