[libvirt] PATCH: Allow LXC to use private /dev/pts instance

[Serge E. Hallyn]

Quoting Daniel P. Berrange (berrange at redhat.com):

> extra SHARED flag, since the only process libvirt_lxc spawns is the 'init'
> process inside the container and that immediately makes its own root
> private.

Thanks, this looks good.
