Ubuntu 10.10 will update kernel to contain a back ported kvm fix, which
probably in the next version after 2.6.35.24. Meanwhile, it is possible
to manually build newer version of kvm to have the problem fixed.
The tar ball of kvm source code could be downloaded from below:
http://sourceforge.net/projects/kvm/files/kvm-kmod/2.6.37/
I tried the package on my Ubuntu 10.10 (kernel 2.6.35.23) T61 laptop
with Intel Core 2 due 32-bit CPU. Using the new kvm, I could boot up
meego kernel successfully. Hope that could help. Thanks!

Bug description:
Binary package hint: qemu
Guest kernel hang during boot when KVM is active on i386 host
See the patch.
http://www.spinics.net/lists/kvm/msg40800.html
How to reproduce:
1. install Maversick x86 (not amd64)
2. ensure you have kvm support in processor
3. kvm -kernel /boot/initrd.img-2.6.35-24-generic-pae
4. kvm -no-kvm -kernel /boot/initrd.img-2.6.35-24-generic-pae works OK.
SRU Justification:
Impact: Users cannot boot KVM guests on i386 hosts
2. How bug addressed: The upstream commit at
http://www.spinics.net/lists/kvm/msg40800.html fixed it
3. Patch: A kernel patch is attached to this bug.
4. Reproduce: boot an i386 kernel on a kvm-capable host. Try to boot a kvm
guest.
5. Regression potential: since this is cherrypicking a commit from a future
upstream which had already been changed, regression is possible. However if
there is a regression, it should only affect users of KVM on i386 hosts, which
currently fail anyway.
