libvirt users - Oct 2014 - How could the admin do to grant me with permission to run virsh as unprivileged user?

Thank you! How could the admin do to grant me with permission to run virsh as
unprivileged user? Also by configurating libvirtd.conf, unix_sock_group?

Hi all! 
Do you have any idea about the following error message from virt-manager. I was
trying to start it with "sudo virt-manager". Do you think I can fix
this by simply restarting libvirtd?
Regards, 
Allen 

Error starting Virtual Machine Manager: Failed to contact configuration server;
some possible causes are that you need to enable TCP/IP networking for ORBit, or
you have stale NFS locks due to a system crash. See
http://projects.gnome.org/gconf/ for information. (Details -  1: Could not send
message to GConf 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.)

Traceback (most recent call last): 
  File "/usr/share/virt-manager/virt-manager.py", line 383, in

  File "/usr/share/virt-manager/virt-manager.py", line 315, in main 
    config = virtManager.config.vmmConfig(appname, appversion, glade_dir)

Hi all, 

What is the difference between starting virt-manager by "virt-manager"
and by "sudo virt-manager"? It seems that there are two copy of
virt-manager running in the background.

When I run "virt-manager", I got a error of "Unable to open a
connection to the libvirt management daemon. Libvirt URI is: qemu:///system
Verify that: - The 'libvirtd' daemon has been started".

Whereas when I run "sudo virt-manager", I got a error of "Error
starting Virtual Machine Manager: Failed to contact configuration server; some
possible causes are that you need to enable TCP/IP networking for ORBit, or you
have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/
for information."

How should I deal with the two issues respectively? Is there any drawback by
simply running "virt-manager"?

Regards, 

Allen

You should set up correct permissions for libvirtd (cf. libvirtd.conf, 
unix_sock_group) and use virt-manager/virsh as unprivileged user.
