I am using the OpenVZ 2.6.16-026test012 kernel patch on a x86_64 Debian host system.

When trying to run Xorg from within an Debian Unstable virtual machine I get the following error (Complete Xorg log at the bottom of the message) :

Quote:

Fatal server error:
xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)

(WW) xf86CloseConsole: KDSETMODE failed: Bad file descriptor
(WW) xf86CloseConsole: VT_GETMODE failed: Bad file descriptor

When I look for the different TTY devices I get the following (ls -al /dev/tty*) and I can not change the permission on tty0.

Quote:

crw-rw-rw- 1 root tty 5, 0 Jun 27 15:05 /dev/tty
crw-r--r-- 1 root root 4, 0 Jun 26 13:48 /dev/tty0

Can anybody give me a hint on how to proceed getting xorg working inside the virtual machine?

regards,
RUben

Just to be clear, I have read the following page on the wiki :
http://wiki.openvz.org/X_inside_VE

The difference is that I need to start X within the virtual machine to enable remote access using the nx ( http://www.nomachine.com ) libraries.

from your quote it follows that your X is trying to access hardware, which looks really strange for me.

1. are you sure, that NX does the same as Xvnc? it should not require any direct hardware including tty's then. Also this should imply some limitations imho.

2. You can try to grant access to /dev/ttyX devices to VE. To do so, use:

host# vzctl set VEID --devnodes /dev/tty:rw
host# vzctl set VEID --devnodes /dev/tty0:rw

3. I recommend to update to 014 kernel Smile

It should be much better and more stable.

4. you can try to give me an access and instruction on what you run/how to connect etc. I can try to help a bit.

1. I believe NX really needs to start up the entire X environment on the server. As if you were really working on a screen and keyboard attached to that machine. So for the moment I actually try to start the X server using GDM.

2. Next week (after my short holiday Cool

) I will try to grant the VE access to the /dev/tty0 device the way you describe. I assume it is possible to grant multiple VEs access to the the hardware this way.

3. As for upgrading to test014, this will be also done after my holiday. Just need to remember how to get the 3ware 9550X-8 raid module in place to boot correctly.

4. I will first try to get it working myself. Need to learn a little bit more on OpenVZ VEs, X in OpenVZ VEs and X in general anyway. If I can not solve this problem anytime soon I will gladly accept your offer.

thx for the hints,
Ruben

vzctl set <VEID> --devices c:4:7:rw --save

Makes tty7 working, but there is then the another problem

X :0 vt7

outputs

xf86PciVideoInfo is not set
Could not get primary PCI info
Aborted
