Subject: [PATCH] lxc: fix starting a domain with non-strict numa memory mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

 # virsh -c lxc:/// start helloworld
 error: Failed to start domain helloworld
 error: internal error: guest failed to start: Unknown
 failure in libvirt_lxc startup

Return success when there are no cpuset.mems to be set,
instead of failing without setting an error.
