OpenSUSE 12.3 dom0 does not see cpus.

English Virtualization

Hello,

I have used earlier releases of OpenSUSE with xen and have not encountered any problems (yet). I have access to one of them now which has helped me diagnose this problem to a degree.

Recently I acquired an HP ENVY dv7 with an intel 3630qm and 8mb of ram.

I installed OpenSUSE 12.3 and the virtualization tools via Yast.

Using the standard procedure I have used in the past, I have not been able create any virtual machines.

Upon further investigation, I realized that the virtual machine manager was not connected to Dom0.

When I attempted to connect to Dom0, the application disappears from the desktop.

Investigating further, I compared the log files contained in

/var/log/xend.log

In the machine which is functioning properly, 8 cpus are noted. (log segment next reformatted for readability)

In this machine only 1 cpu is seen (log segment?)

I have attempted to find the reason for this and in the course of my reading I found that YAST had not installed qemu (same as 13.1), but installing that didn’t help.

What is the problem here?

Is there any other information needed to diagnose this problem?

What do I need to do to fix it?

Thanks in advance

update:

This problem was solved by a fresh install on the laptop.

I installed 12.3 on the desktop and of course Xen ran fine. (There was never any doubt in my mind, but I had to confirm it.)

I used the same procedure on the laptop which was:

1) Install taking most defaults
2) Set up wired connection to network
3) Install all recommended updates rebooting when directed.
4) Install Xen setting up the suggested default bridge and rebooting when directed into Xen.
5) Start virtual machine manager which reflects dom0 running.
6) With dom0 running assume everything is hunkydory.

Hope this helps someone.

Regards
