[libvirt] libvirt_lxc start problem when selinux enbale

Hi，all： the problem came out when selinux was enforced in targeted+MCS I start lxc through virsh――“virsh -c lxc:/// start instance-00004bd6” 1. When selinux is Permissive，lxc start is ok The result of “Ps auxZ” is： system_u:system_r:virtd_lxc_t:s0-s0:c0.c1023 root 19218 0.0 0.0 47624 1244 ?

When selinux is Enforcing，lxc start bad Th result of “ps auxZ” is: system_u:system_r:virtd_lxc_t:s0-s0:c0.c1023 root 20624 0.0 0.0 47624 1244 ?

This is the real problem There is avc error messages in dmesg、/var/log/messages、/var/log/secure, and the same with selinux is Permissive Can anybody give some hints?
