Open Stack

Look at the log of libvirt or type the following command:

 virsh -c qemu:///system list

Will get the error message:

ERROR：authentication failed: polkit:
polkit\56retains_authorization_after_challenge=1
Authorization requires authentication but no agent is available.

That's an issue of libvirt configuration.

[SOLVED]

uncomment

 auth_unix_rw = "none"

in /etc/libvirt/libvirtd.conf and restart libvirt-bin.

Hope this can be useful for those we have the same problem.
