Hi experts,

I want to have a test on security driver for libvirt lxc on my debian system.
What I do is as the following steps:
1) download the source code from git://libvirt.org/libvirt.git
2) compile and install with the source code as following:
./autogen.sh --system
 ./configure --with-selinux=yes --with-secdriver-selinux=yes
make -j8 & make install

root@debian:~/github/libvirt.git/tools# ./virsh --version=long
Virsh command line tool of libvirt 1.2.8
See web site at http://libvirt.org/
Compiled with support for:
 Hypervisors: QEMU/KVM LXC UML OpenVZ VMWare VirtualBox Test
 Networking: Remote Network Bridging Interface udev Nwfilter VirtualPort
 Storage: Dir Filesystem SCSI Multipath LVM
 Miscellaneous: Daemon Nodedev SELinux Secrets Debug Modular

3) then I define a lxc vm with the seclabel :
root@debian:~/images# vir dumpxml lxc
<domain type='lxc'>
  <memory unit='KiB'>419404</memory>
  <currentMemory unit='KiB'>419404</currentMemory>
  <vcpu placement='static'>1</vcpu>
    <type arch='x86_64'>exe</type>
    <cmdline>console=tty0 console=ttyS0</cmdline>
  <clock offset='utc'/>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/tmp/rootfs'/>
      <target dir='/'/>
    <console type='pty'>
      <target type='lxc' port='0'/>
  <seclabel type='dynamic' relabel='yes'/>

4) When I start the vm, It output an error:
root@debian:~/images# vir start lxc
error: Failed to start domain lxc
error: unsupported configuration: Unable to find security driver for label selinux

What's the problem?
Really appreciate for any help.
Best Regards
