this might help mysterious reboots that I get (daily it seems) from my 2003server guest (XP host).

so do we change the host or guest registery?

Sorry for not being clear there - you make the change in the guest registry.

Cheers,

So that's why VirtualPC doesn't work right on my (Centrino) laptop!

Also, rather than wondering around in the registry, you're better off using "SC" command (included with Windows XP/2003), like this:
sc config processor start= disabled
sc config intelppm start= disabled
This is in the guest OS, of course.

Thanx, Ben & Jonathan. We just slammed into this issue with one of our [Avanade's] clients, but it's going the other way from what you described. A W2k3 image created and sysprep-ed on a Centrino notebook tanked when run on a desktop P4 w/ HT... The processor service couldn't be found on the image, but the "sc config intelppm start= disabled" cured it AFTER I copied the image to the P4 BEFORE running sysprep. Thank you!! Note that it didn't work when I disabled intelppm and sysprep-ed on the Centrino and then tried to run it on the PCs...

Ben,

FYI, I have the problem consistently on my DELL XPS Gen 4 (Intel P4 3.6 GHz, hyperthreading on) running Windows XP Media Center 2005.

Cheers,

Brian

Note: I had to use the SC commands at a Safe Mode with Command Prompt because my VPC Instance couldn't even login without blue screening. After applying the two changes in Safe mode everything works fine.
