A while back I reported a crash starting with kvm-29 with Windows XP guest on AMD processors.

kvm-33 still fails for me, so I tried to use the kvm git kernel module, (after using make sync LINUX=../../kvm.git from kvm-33 directory), but the compile fails with (on the 2.6.20 ubuntu feisty kernel)

/home/john/software/kvm/kvm-33/kernel/kvm.h:302: error: field ‘preempt_notifier’ has incomplete type

So I switched the kvm branch to "for-linus" and did a make sync. This compiles and runs, but Windows XP still crashes.

Then I notice that bac27d35cbbf7c641efcc75b5330df8717d6db65 shows up in linus's tree, but not in the for-linus kvm branch.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=bac27d35cbbf7c641efcc75b5330df8717d6db65

So applying that small patch on top of the for-linus kvm branch, and then doing make sync from kvm-33, the windows XP guest boots up and works fine.

It would be nice to get a kvm-34 that includes this (and the other changes)

This is fixed now, I think -- I'll check whether I forgot to push.

Note that for-linus is a temporary branch and is not maintained outside the merge window. The nearest equivalent is Linus' tree.

Due out real soon now. It was delayed by travel and by smp migration fixes.
