Per the docs:
http://libvirt.org/drvlxc.html#envvars
pid 1 inside lxc inherits $container_uuid into its environment variables.
Thanks
for help.
But in my lxc container, It seems no such envvars existed:
root@debian:~# ps auxf

root@debian:~# echo $container_uuid
root@debian:~# echo $LIBVIRT_LXC_UUID
The version of libvirt I used is 1.1.4.
Do this libvirt version support the lxc envvars feature?
