When i start virt-manager and try to collect to localhost I get this: ======================= Unable to connect to libvirt. authentication failed: polkit: polkit\56retains_authorization_after_challenge=1 Authorization requires authentication but no agent is available. Libvirt URI is: qemu:///system Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 1002, in _open_thread self.vmm = self._try_open() File "/usr/share/virt-manager/virtManager/connection.py", line 984, in _try_open flags) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 102, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: authentication failed: polkit: polkit\56retains_authorization_after_challenge=1 Authorization requires authentication but no agent is available. ======================= Using virsh on the command line seems to work fine.
I just checked on the machine itself and there it works. The issue only seems to occur when the virt-manager display is exported to another machine (i.e. "ssh -X" to the machine and then starting virt-manager).
