There was a bug in kvm that caused changes to memory mapped at 0xe0000-0xfffff to also be reflected in the "rom" image at 0xfffe0000-0xffffffff. It was my understand that this bug was fixed though.
You are great! Disabling KVM for the guest (/domain/@type='qemu') made the reboot work on both the RHEL-6 devel version of qemu and on upstream 1.3.1.
(I didn't try suspend/resume yet.)
Do you recall the precise commit that fixed the "reflection"? I've been eyeballing kvm commit messages for a few ten minutes now, but of course in vain. (CC'ing Gleb and Marcelo.)
I found this email thread:
