[libvirt] [PATCH RESEND 0/7] LXC: enhance user namespace support for adding the disk and host devices for libvirt lxc

Libvirt lxc has supported user namespace since commit c34107dfd3a25232255e6d6f559b1306ef99bb3b,but for the disk devices and hostdevs, libvirt lxc still creates these device nodes in container. this will fail when container enables user namespace, since user namespace is disallowed to create device node. In order to reslove this problem, we should create device nodes on host side for container,and change the owner of these nodes to the root user of container.
