Unfortunately hacking on the code requires much poring over ancient 
manuscripts, a thorough understanding of the glorious history of the x86 
architecture, and much banging of heads against walls.  So unless you're 
prepared to spend quite a bit of time on kvm, your best bet is in testing.

Having a regression test of a real workload with timing measurements 
always helps, prefereably with multiple virtual machines running 
concurrently.

What guest are you running?  At what stage are you seeing the problem?  
Usually the workaround involves disabling the bootloader splashscreen or 
switching bootloaders.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
