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

Mon Oct 27 17:16:07 UTC 2014

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.)

    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.
