[libvirt-users] How to give access to /dev/tty
Hello,
First I apologize because I sent this email on the lxc-users mailing
by error. So sorry for the double message.
I'm trying to run an X server inside a container. I was able to
achieve this with lxc-tools (and that is why I mixed myself between the
2 lists) by setting the option lxc.tty = 4 that allows access to 4 tty.
Now I want to use libvirt because my final goal is to create a
container with GPU capabilities from Openstack (that uses libvirt).
When I start an X server with "startx -- :1" in a container I have the error:
Fatal server error:
xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)
I also tried with :2 and :3 but I still have the same error (except
that the name of the log file changed between Xorg.{1,2,3}.log. I
copied the xml file of my container at the end of the email.
Thus my question is how can I give an access to /dev/tty0 to the
container? Or maybe it is not the right way to start an X server in the
container. Best regards,
Guillaume
