I'm running Ubuntu 12.04.2 32 bits.

The error doesn't show up if I start gksudo virt-manager.

  • libvirt-bin is installed.
  • I don't know how to check for the daemon.
  • I am a member of libvirtd.

Output of ps ax | grep libvirt:

9225 ? Sl 0:04 /usr/sbin/libvirtd -d
9302 ? S 0:00 /usr/sbin/dnsmasq -u libvirt-dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases --dhcp-lease-max=253 --dhcp-no-override`

Output of ls -l /var/run/libvirt/libvirt-sock:

Output of getent group libvirtd:

What are the contents of your /etc/libvirt/libvirtd.conf file? –  Bruno Pereira Sep 13 '13 at 19:41

Sometimes stupidity is the cause.

Rebooting the host OS solved the issue.
