Hi !
| Quote: |
the main problem is to achieve hardware from inside the VE.
Why don't you start additional X server inside VE0 (or inside external machine) and X applications (or complete X environment) inside VE?
|
I want to set up a machine with a LAN server, an internet server and a desktop. So I use openvz to separate the LAN server and the internet server and I thought it would be nice to separate also the desktop. I know that I can run the X server inside VE0 and X environnement inside VE, but I thought it would be nice to have no big application running on VE0. Perhaps that is a stupid assumtion, given that giving a VE enough capabilities to run X is perhaps not better than running X inside VE0. Anyway I began to investigate and would have been happy to find a solution.
Googeling the web I found nobody successfuly running X server on openvz, but lots of people doing that on vservers, so I think it's possible.

Could you possibly describe what has been done?
What kind of capabilities did you grant to VE, what kind of devices you had to create? What kind of xorg configuration file do you use?
|
What I tried on a testing machine (on which X runs also on VE0 and which is NOT my server) :
sudo aptitude install xserver-xorg udev_
vzctl set <VEID> --capability sys_rawio:on --save
vzctl restart <VEID>
vzctl set <VEID> --devices c:1:1:rw --save
vzctl set <VEID> --devnodes mem:rw --save
vzctl set <VEID> --devices c:4:0:rw --save
vzctl set <VEID> --devnodes tty0:rw --save
vzctl set <VEID> --devices c:4:8:rw --save
vzctl set <VEID> --devnodes tty8:rw --save
vzctl set <VEID> --devices c:10:1:rw --save
vzctl set <VEID> --devnodes psaux:rw --save
vzctl set <VEID> --devices c:13:63:rw --save
vzctl set <VEID> --devnodes input/mice:rw --save
A also tried these, which didn't changed anything, then I removed them :
vzctl set <VEID> --capability ipc_lock:on --save
vzctl set <VEID> --capability ipc_owner:on --save
vzctl set <VEID> --capability sys_admin:on --save
vzctl set <VEID> --capability net_admin:on --save
vzctl set <VEID> --capability net_raw:on --save
vzctl set <VEID> --capability mknod:on --save
vzctl set <VEID> --devices c:10:175:rw --save
vzctl set <VEID> --devnodes agpgart:rw --save
The Xorg.conf I use on the machine on which I run the tests (which have Xorg in VE0) is nearly exactly the same that works on VE0:
# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

Do you think that /proc/bus/pci/02/00.0 whould be sufficient? Could you please show the output while X server is starting inside VE?

I try to start X with :
