[libvirt] how to connect LXC via libvirt

Hi Daniel, I followed the instructions in: https://lists.linux-foundation.org/pipermail/containers/2008-September/01323... to try to connect with LXC which is built in my VM (ubuntu7.10 + kernel 2.6.27-rc8). Unfortunately, I fail. The container can work when I use its user-space interfaces, however I can not execute the "virsh --connect lxc:/// define mycontainer.xml" after I have installed the libvirt (downloaded from CVS). I checked the libvirt.c and found there are only the "xen:///" support, not any codes to support LXC. Therefore, I am wondering whether LXC has been supported in libvirt mainstream and what should I do to get the result as your statement in maillist. Thanks, Ian
