Copied from #11271 and #11378
Some findings of the QEMU-KVM issue on Ubuntu 10.10.
The QEMU-KVM hung during booting up meego-netbook kernel. The netbook kernel is
2.6.35 with some Intel patches. I did below test:
QEMU:
1, qemugl in MeeGo 1.1 SDK, which version is 0.12.4
2, qemu installed from Ubuntu 10.10 repo, which version is 0.12.5
Kernel:
a, handset netbook kernel in MeeGo 1.1 release, major version is 2.6.35
b, Ubuntu 10.10 kernel, major version is 2.6.35
Result
1 to boot a FAIL
1 to boot b SUCCESS
2 to boot a FAIL
2 to boot b SUCCESS
So the problem is quite like that MeeGo kernel has something special which
cannot work well with the KVM in Ubuntu 10.10 host kernel.

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