[libvirt-users] How to get uuid info inside a lxc container created by libvirt_lxc
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? Thanks for any help~ -- ------------ Jackie Best Regards

Per the docs: http://libvirt.org/drvlxc.html#envvars pid 1 inside lxc inherits $container_uuid into its environment variables. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

Do this libvirt version support the lxc envvars feature?

Look at the environment of the process with PID 1: # tr '\0' '\n' < /proc/1/environ -- Claudio
