Hi All,
trying to start the xorg server in the container I receive the following
messages:
[ 61645.425] (II) NVIDIA dlloader X Driver 340.65 Tue Dec 2 08:47:36 PST 2014

startx /usr/bin/startx -- :10 vt10
fails as we do not have /dev/tty10 yet:
Fatal server error:
(EE) xf86OpenConsole: Cannot open virtual console 10 (No such file or directory)
mknod -m 666 /dev/tty10 c 4 10
startx /usr/bin/startx -- :10 vt10
gives again:
Fatal server error:
(EE) xf86OpenConsole: VT_ACTIVATE failed: Inappropriate ioctl for device
the lxc config has lxc.cgroup.devices.allow = c 4:10 rwm
one difference between the container and the host system is that major numbers
for tty devices are different:
inside container:
ls -l /dev/tty*
crw-rw-rw- 1 root root 5, 0 Jan 16 11:44 /dev/tty
crw------- 1 root tty 136, 1 Jan 16 12:06 /dev/tty1
crw--w---- 1 root tty 136, 2 Jan 16 11:44 /dev/tty2
crw--w---- 1 root tty 136, 3 Jan 16 11:44 /dev/tty3
crw--w---- 1 root tty 136, 4 Jan 16 11:44 /dev/tty4
where on the host system they have MAJOR number 4.
I've tried templates with ubunty trusty, debian jessie and wheezy with no
luck, the startx fails on xf86OpenConsole.
LXC version on the host system: 1:1.0.7-1
System Debian Jessie, kernel verision: 3.16.0-4-amd64
Any hints will be greatly appreciated.

Have you tried to use a login-shell (ie. /bin/bash -l)?:
lxc-execute -n vm3 -f vm3/lxc.conf -- /bin/bash -l
In this case /etc/profile will be executed.
And there one can export some needed environment variables.
I'm not sure if the following can be relevant in your case, but it was for me:
For example in my case (GUI desktop with LXDE already running on host)
I must after each starting of a container do "export TERM=xterm"
to be able to use other text editors than vi (for example joe, nano),
because w/o this, TERM gets set to "dumb" or "unknown" and the said editors
cannot start.
