Thanks. Using bypass_guest_pf=0 and irqchip_disable() brings things
back to -41 level of functionality.

kvm not expecting both guest and host app changing pagetables could
explain other problems I'm seeing though, so maybe i better fix that.
Long term it isn't planned to stay that way anyway, it's just handy for
proof-of-concept because userspace is very easy to hack and debug ...

thanks,
