Xen on Ubuntu 8.10 64bit problems

[Chromium]

After performing the following commands on the latest 8.10 Desktop 64bit:

sudo aptitude install ubuntu-xen-server
sudo apt-get install xen-tools
sudo reboot

The Xen kernel does not load:

admin@356835794:~$ sudo xm list
ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
Traceback (most recent call last):
  File "/usr/sbin/xm", line 8, in <module>
    from xen.xm import main
  File "/usr/lib/python2.5/site-packages/xen/xm/main.py", line 61, in <module>
    xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')
adminuser@356835794860:~$ sudo uname -r
2.6.27-7-server
admin@356835794:~$

Does anyone have an idea why?

On Ubuntu 8.10, the Xen kernel is only for domUs, but not for dom0 - there's no dom0 kernel because the Xen project didn't create any patches for the latest kernels...

Yeah, figures...

It's alright though, that VirtualBox works great. Very impressed with it, took me all but 10 minutes to get that going

I've written a tutorial for Xen on Ubuntu 8.10. Will publish it in the next days.

Hey!

I need some help on this. I am running:

Ubuntu 9.10 and
Kernel 2.6.31-15-generic-pae

When I try to run any xm command, I have the same error as mentioned above, namely:

pbhat@pbhat-acis:~$ xm list
ERROR Internal error: Could not obtain handle on privileged command interface (2 = No such file or directory)
Traceback (most recent call last):
File "/usr/sbin/xm", line 8, in <module>
from xen.xm import main
File "/usr/lib/python2.6/dist-packages/xen/xm/main.py", line 61, in <module>
xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')



I understand that my kernel not being able to support Dom0. However I do not know how to go about solving the problem. Could someone elaborate on where I need to put the earlier kernel (hardy) version so that dom0 can use it to boot and which files I need to edit?

Thanks
