Ok. I compiled kvm-60, loaded the modules and tried something simple
as usual.

Unlike previously, the host didn't reboot, and kvm window stayed
blank. But now there's at least something in dmesg:

loaded kvm module (kvm-60)
emulation failed (pagetable) rip fff0 00 00 00 00

Is it something which can help?

Thanks!
