I'm running a couple of LXC guest on an Ubuntu 12.04.2 host. The 10.04 guests can access the VT's(text) just fine. However, the 12.04 guest cannot. The only thing I can find in syslog which looks relevant is:
Feb 2 22:52:11 lts console-kit-daemon: WARNING: Could not determine active console Feb 2 22:52:11 lts console-kit-daemon: WARNING: Error waiting for native console 21 activation: Invalid argument Feb 2 22:52:11 lts console-kit-daemon: WARNING: Error waiting for native console 25 activation: Invalid argument ... ...
I've followed the same routine as for the 10.04 guest and double checked it several times for errors. The only difference I noticed with the config files is the 12.04 file has this line:
lxc.devttydir = lxc
Whereas the 10.04 config file has this line
I tried changing it and it made no difference.
All guests were created using the Ubuntu templates.
Any help greatly appreciated.
