external module compat hard codes tsc_khz as 200 if KERNEL_VERSION
(2,6,23).
This breaks kvmclock on hosts with different frequency.
While tsc_khz was only exported on 2.6.23, the majority of relevant
older v2.6 based distros seem to have it

you can test kvm-84 bios with:

That will force qemu to look in the kvm-84 pc-bios dir
Hi Avi,
I spent some time today putting together an approximation of the KVM
stable release based on QEMU 0.10.x. In principle, it's not too bad at
all because it's just a matter of creating a branch in kvm-userspace
that's based a kvm commit sometime after the QEMU 0.10.x release but
IMHO, one thing you should keep in mind is how to isolate the guest space based
on your hardware MMU.
And then deal with the exceptions carefully,
some may be directly send to guest and some should be handled by hypervisor.
In powerpc BOOKE implementation, we have to hijack all exceptions,
