I have been testing converting working openvz guests to lxc without
success. I have two basic problems.
1. The lxc guest is taking over the virtual terminals of the host.
2. The lxc guest pauses randomly for a few seconds.
I am using gentoo as the host (under virtualbox for testing so I do
not disturb the real openvz host) and guest using containers that work
under openvz specifically 2.6.27 openvz kernels.
