With some tweaks that maybe possible, but IMHO it is not adequate. Lxc is not like QEMU/KVM or Virtualbox, the hardware is not virtualized, so you may have conflicts with the differents X server because they will share the same hardware (eg. different resolutions in different containers). I use ssh with X forwarding and that works like a charm. Another solution, maybe to use a ltsp server within a container, so the different client will have their own desktop environment (these ones have to be diskless). > I have read various things via google on the subject and believe that the > container needs access to the graphics hardware device (in my case, > /dev/nvidia0), /dev/input/mice and /dev/mem. > > I have been unable to set up access to the latter two via cgroups in the > container configuration file and I have been unable to create device files > in the container for them. > > lxc.cgroup.devices.allow = c 195:* rwm # dev/nvidia* > lxc.cgroup.devices.allow = c 1:1 rwm # dev/mem > lxc.cgroup.devices.allow = c 13:63 rwm # dev/input/mice > > If the last two are present, the container will not start.
