[libvirt] [RFC PATCH 0/6] Add user namespace support for libvirt lxc

[Gao feng]

This patchset try to add userns support for libvirt lxc.
Since userns is nearly completed in linux-3.9, the old
kernel doesn't support userns, I add some New XML elements
to let people decide if enable userns.The userns is disabled
by default.

And because the uninit userns has no right to create devices,
so we should create devices for container on host.

This patch alse changes the owner of fuse and tty device.
Cgroupfs is unavailable in userns now,so don't mount cgroupfs
when we enable userns.

Gao feng (6):
  LXC: New XML element for user namespace
  LXC: introduce virLXCControllerSetupUserns and lxcContainerSetUserns
  LXC: only mount cgroupfs when userns is disabled
  LXC: Creating devices for container on host side
  LXC: create tty device with proper permission for container
  LXC: fuse: Change files owner to the root user of container
