[libvirt] Can not display graphical console of lxc Virtual Machine.

Hi all, I am trying to display the graphical console of a lxc virtual machine which was already created and running. For this, I am using 'virt-viewer'. But, when I execute the following command, it's throwing some errors. [root@localhost lxc_devel]# virt-viewer --connect lxc:/// vm2_fedora --debug ** (virt-viewer:11988): DEBUG: Add handle 4 1 0x217c140 ** (virt-viewer:11988): DEBUG: Add timeout 0x217e4f0 -1 0x7fda386cb990 0x217c140 1 ** (virt-viewer:11988): DEBUG: Skipping inactive resize ** (virt-viewer:11988): DEBUG: Failed to activate viewer can anyone help me. Please suggest me if any other ways of doing it. Regards, Srikanth.
