this patch addes fuse support for libvirt lxc. we can use fuse filesystem to generate sysinfo dynamically, So we can isolate /proc/meminfo,cpuinfo and so on through fuse filesystem. we mount fuse filesystem for every container. the mount name is libvirt,mount point is localstatedir/run/libvirt/lxc/containername.
