Hi ,
Is there anyway to get uuid info inside a lxc container which is created
by libvirt_lxc?
For kvm, we can use dmidecode or lshw to get this info inside vm. Is
there any tools
to do this thing for libvirt lxc?
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:~# 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?
