libvirtError: internal error cannot determine default video type

I've tried lxc using the latest version. But the following error occured.

The version I used is 2011.2~bzr932-0ubuntu0ppa1~maverick1.

Yes, I hit that one as well, on Natty.

[Serge Hallyn (serge-hallyn)]

Please try adding:

lxc.cgroup.devices.allow = b 43:* rwm

to the container's config file, and let us know if that works.

[guanxiaohua2k6 (guanxiaohua2k6)]

I've tried, but it failed again. Maybe I made a mistake on the place of config file. Could you tell me where is the config file? and after make a change, does it need to restart some service?

Thanks.

This is due to the fact that lxc is trying to use vnc by default which is not supported by LXC, ill have a fix shortly.
