I installed virt-manager and I am unable to make it work.

I have tried some of the previously posted answers with no success. I've verified that:

  • The libvirt-bin package is installed
  • The libvirtd daemon has been started
  • I am a member of the libvirtd group
  • libvirt URI is: qemu:///system

This is the error I get when trying to run virt-manager:

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
  File "/usr/lib/python2.7/dist-packages/libvirt.py", line 102, in openAuth
    if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Permission     denied

Please, edit your question to include the output of ls -la /var/run/libvirt/. –  Eric Carvalho Jul 11 '13 at 14:32

I had the same issue. Try this guide it's works for me. Don't forget relogin after add user to group 'libvirtd'

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  Eric Carvalho Jan 30 '14 at 19:20

Try to add this line to /etc/libvirt/libvirtd.conf

listen_tls = 0

then restart lirvirt by:

/etc/init.d/libvirt-bin restart
