[libvirt-users] Does libvirt support attach volume to linux container now?

Hi all, I am playing with linux container and using libvirt to manage linux container. I find I fail to attach volume to linux container via libvirt and I got the following error message: Failed to attach volume: data-111 to VM: lxc-111; org.libvirt.LibvirtException: unsupported configuration: Can't setup disk for non-block device. My question is that does libvirt support attaching volume to linux container? If it supports, what version should I use? Thanks, DuJun
