Hi !

I'm trying to find out how to add entries in /proc of an openvz container, and I found no documentation at all. A only find information on adding /dev entries (with vzctl --devnodes).

What I'm tring to do is to add /proc/bus/pci in a container. Is it possible ?

Thanks by advance !

Hello,

why do you need to get such information from inside the VE?

Because I'd like tu run X. Please don't tell me it's stupid, I know it could be, I just wanna do it fore some reason. If that's a problem for you just don't waste your time to answer.

I hope anyway that some people will answer me !

Thanks by advance.

Thanks, but that was where I began and it does NOT cover the topic on how to run an X server inside a VE, it only covers "ways to run X applications inside your container" using another X server for the display.

I invesigate and I really think that I miss /proc/bus/pci/02/00.0 inside the VE.

Hello,

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?

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?

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 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.

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.

(II) Primary Device is: ISA
(EE) No devices detected.

Fatal server error:
no screens found

So I guessed that X didn't found PCI device. I compared strace of Xorg outside and inside openvz and I noticed that inside openvz that failed :

+stat0("/proc/bus/pci", 0)     = -0 ENOENT (No such file or directory)

And I guessed (error ?) that it especially needed the PCI 1:0:0 which is the one my craphic card is on.

I think that's all...

A crazy but workable advice (I was able to run KDE environment inside VE) Smile

Smile

:

Mount /proc from HN to VE. i.e.:

# umount -l /vz/root/$VEID/proc
# mount -t proc proc /vz/root/$VEID/proc

But seriously speaking you'd better run X server on the HN and all window stuff inside VE. It's not a big restriction but it provides isolation.

It isn't possible to configure which devices appears in a VE's proc, as it's possible to do in a VE's dev ?

well....

the easiest way to run the desktop in VE is to install for example KDE without X at all... I just install nxserver and access the VE desktop with little, remote X server from nxclient package.

regards.

PS. I see no reason to run Xorg inside VE, if I'm not able to login remotely.

Well, first things first. As far as I know, there is NO WAY you can run an X server inside a VE for various reasons.

But here is an idea: you can start gdm and run a full X desktop in the VE.

Put this in /etc/gdm/gdm.conf:

[daemon]
VTAllocation=false

[security]
DisallowTCP=false

[xdmcp]
Enable=true

[gui]

[greeter]

[chooser]

[debug]
[server-false]
name=false
command=/bin/false

[servers]
0=false

And then restart gdm.

On some another machine:

Xnest :1 -query VE_IP_ADDRESS -geometry 800x600

Be aware of the security impact of enabling XDMCP.

I tried this.

- With ati driver, X starts a little more, but "freezes" my display.

- With vesa driver, this works !

As you said, I'm not sure at all it's a good solution, but at least it works.

Thanks !

Hi, can you explain what you've actually tried and worked?

I have also wanted to be able to access some kind of display device from HN inside VE.

But the concept of displaying your HN and a VE from the same video card already sounds conflicting: which machine should your monitor display? (HN or VE)?

So I was thinking of using 2 video cards or video cards with 2 displays, and pass the second display access to one of the VE we want to run X. So please help me on what is already being tested. And you mentioned that people who use Vserver has already done things like this?

Just following up my own question. Doesn't the display get confused of which one to display?

The screen is showing VE0 or the container you have installed full X Server on?

What if I don't have full XServer installed , I just want to show the command line screen of the container on screen . Without doing vzctl enter VEID , can I still view the container by using the method in this thread?
What do I do after I have done the following:

Mount /proc from HN to VE. i.e.:
# umount -l /vz/root/$VEID/proc
# mount -t proc proc /vz/root/$VEID/proc
