3.0.12 not playing nice with Centos 5.4?

I have a VM I built yesterday using VB 3.0.10 and Centos 5.4 64 bit on a Ubuntu 9.04 64 bit host. Everything worked fine.

This morning I upgraded to 3.0.12 on the host machine, and the Centos VB now won't start. The error message is:

NMI Watchdog detected LOCKUP on CPU 0

Two other VB machines (one host with Ubuntu and one with Debian) on the same host built seem to work fine. Has anyone else run into this problem? I searched the forum for the error message, but found no results. A google search found a blog entry for one person who has the same problem, but no solution was posted.

Any suggestions? Should I just downgrade to 3.0.10?

Thanks!

You can add "nmi_watchdog=0" to the kernel boot parameters. That worked for me. Maybe this will be fixed for 3.1.0.

That's a little over my head. How do I access the kernal boot parameters if I can't get the VM to start? Or is that a setting for the virtual machine itself, and I just add that with a command line on the host?

In the meantime, I uninstalled 3.0.12 and reinstalled 3.0.10. The Centos VM works fine.

Thanks!

At the boot screen for CentOS 5.4, press 'a' to append to the kernel boot line. This occurs very early in the boot sequence and you only have a few seconds to do this.

Then type "nmi_watchdog=0" and press RETURN to resume the boot sequence.

I had this same problem, I'm on a Win 7 host running a CentOS 5.4 guest.
I have used the Kernel Parameter method, which worked perfectly, thank you Exillis :D

I also have XP and Fedora 11 guests, none of which have had any problems after the upgrade.
:mrgreen:

Exillis, thanks a million, this did fix it for me too. The problem started after my first boot since I upgraded from 2.2.2 to 3.0.2. Until I rebooted it was running fine.
