[PATCH] lxc: Set default security model in XML parser config
Attempting to create a lxc domain with <seclabel type='none'/> fails
virsh --connect lxc:/// create distro_nosec.xml
error: Failed to create domain from distro_nosec.xml
error: unsupported configuration: Security driver model '(null)' is not available
The lxc driver does not set a default security driver model in the XML
parser config, causing seclabels of type='none' to have a null model.
The lxc driver's security manager is initialized in lxcStateInitialize()
by calling lxcSecurityInit(). Use the model of this manager as the
default in the XML parser config.

Kind'a, sort'a a V2 of

It's quite a different approach to solving the problem than that patch.
