    virt-manager:Unable to connect to libvirt

    hello,everybody. Recently I installed the latest suse 12.2 on my dell optiplex 390. After I install the xen part and bulid virtual machine on two exactly same machine, I try to connect the other one with virt-manager in YaST, and the error "Unable to connect to libvirt" appears, the details are as below:
    Unable to connect to libvirt.

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

    Verify that the 'libvirtd' daemon is running
    on the remote host.

    Details:
    Unable to connect to libvirt.

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

    Verify that the 'libvirtd' daemon is running
    on the remote host.

    Libvirt URI is: xen+ssh://elab2@192.168.0.66/

    Traceback (most recent call last):
    File "/usr/share/virt-manager/virtManager/connection.py", line 1027, in _open_thread
    self.vmm = self._try_open()
    File "/usr/share/virt-manager/virtManager/connection.py", line 1009, in _try_open
    flags)
    File "/usr/lib64/python2.7/site-packages/libvirt.py", line 102, in openAuth

    Above is under the condition that libvirtd.conf been all commented. Libvirtd service is running. VNC is enabled. rsa_keys is copied. Googled many results, but none solved my problem. Anybody met such a question? Please share your wisdom with me, thanks.

    Plus, When try to start virt-manager in console, the result is as below:
    ** (virt-manager:7835): WARNING **: Trying to register gtype 'GMountMountFlags' as enum when in fact it is of type 'GFlags'

    ** (virt-manager:7835): WARNING **: Trying to register gtype 'GDriveStartFlags' as enum when in fact it is of type 'GFlags'

    ** (virt-manager:7835): WARNING **: Trying to register gtype 'GSocketMsgFlags' as enum when in fact it is of type 'GFlags'

    (virt-manager:7835): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
    Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

    Not 100% sure about this, but I specifically choose to use a Xen connection when remote connecting virt-manager to a Xen host (using SSH RSA keys) and when the host is running as KVM host, then select the default QEMU/libvirt.

    So I'd suspect you are choosing the wrong option to connect with.
