virt-manager


Hi all,

when I'm trying to work with virt-manager on a remote host(ssh -X host) I got the error:
Code:
#virt-manager
Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager.py", line 386, in <module>
    main()
  File "/usr/share/virt-manager/virt-manager.py", line 287, in main
    raise gtk_error
RuntimeError: could not open display
then I reinstall libvirt polkit policycore, log out and ssh again, this time result was:
Code:
#virt-manager
X11 connection rejected because of wrong authentication.
Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager.py", line 386, in <module>
    main()
  File "/usr/share/virt-manager/virt-manager.py", line 287, in main
    raise gtk_error
RuntimeError: could not open display
But sometimes when I'm not the root user and run virt-manager, the virtual machine manager will appear, but it gives me the error:
in console:
Code:
Gtk-Message: Failed to load module "canberra-gtk-module"
and in virt-manager window:
Code:
Unable to connect to libvirt.

authentication failed: Authorization requires authentication but no agent is available.

Libvirt URI is: qemu:///system

Traceback (most recent call last):

    self.vmm = self._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: Authorization requires authentication but no agent is available.

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

You might do better to ask the Mods via the Report button to move this to the Virtualisation forum
