I had some time on my hands lately and tried to debug this a little. I found that there's actually something showing in dmesg: [ 3872.221039] emulation failed but !mmio_needed? rip 9a12 0f 09 66 25 Does that help? I'm running kvm-24 now, but the exception still happens. I've been looking through x86_emulate.c and kvmctl.c trying to print more information but with no success yet.
