The option doesn't exist yet in 2.6.31 which I'm running on this box
because 2.6.32-rc has massive regressions for my workload. I booted
into it again anyway to test the option - and interestingly enough
qemu with -enable-kvm boots just fine even without ignore_msrs=1.
Looks like the problem only happens with older kernels.
