When connecting to libvirt, some connections may require client authentication before allowing use of the APIs. The set of possible authentication mechanisms is administrator controlled, independent of applications using libvirt. Once authenticated, libvirt can apply fine grained access control to the operations performed by a client.

In order to ensure only authorized users can connect, libvirt offers several connection types (via TLS, SSH, Unix sockets, and TCP) that can be combined with different authorization mechanisms (socket, PolicyKit, SASL and Kerberos). 8.1 Authentication #

The user in libvirt group can run virt-manager and virsh without sudo. The problem is discussed on Launchpad and the cause of this problem can be solved by installing the xen-utils package ( xen-utils-4.4 on Ubuntu 14.04).

For example, setting the former to mode 0770 and the latter wheel would let any user in the wheel group connect to the libvirt daemon. UNIX socket PolicyKit auth ¶ If libvirt contains support for PolicyKit, then access control options are more advanced.

@damadam so first he adds <username> to the libvirt group so that that user can run virt-manager and virsh without needing to elevate privileges, then he defines the default path to connect to qemu and saves it in a file (in this case .profile) that will be sourced on startup. Then he reboots the system so that the group change will take effect.

The name of the libvirt hypervisor driver to connect to. This is the same as that used in a local URI. Some examples are xen, qemu, lxc, openvz, and test.As a special case, the pseudo driver name remote can be used, which will cause the remote daemon to probe for an active hypervisor and pick one to use.

Use of this environment variable is, however, deprecated now that libvirt supports LIBVIRT_DEFAULT_URI itself. When using the interactive virsh shell, you can also use the connect URI command to reconnect to another hypervisor. In virt-manager use the -c or --connect=URI option: virt-manager -c test:///default.
