Hi Guys, Recently, I'm doing some tests on openstack with lxc virtualization supported by libvirt. I need some recently new documents about libvirt lxc. Anything related is just ok. Thanks! -------------- Best regards! GuanQiang 2013-07-23

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
