[Qemu-devel] [Bug 688085] Re: Guest kernel hang during boot when KVM is active on i386 host

[Froggy]

Change proposal for Maverick (2.6.35) based on kernel patch in description:
   * kvm_emulate.h:
      * Change struct operand so that val and orig_val will be changed from 
unsigned long to union like this:
            union {
                  unsigned long val;
                  u64 val64;
            }

   * emulate.c:
      * in emulate_grp9() change all occurences of c->dst.val to c->dst.val64.
      * In x86_emulate_insn() change line "c->src.orig_val = c->src.val" to 
"c->src.orig_val64 = c->src.val64".

The MeeGo qemu will start work then.

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.
