First thing, you dont want to have the virtual cpu in a different process than the hypervisor control code for that cpu. Otherwise communication has to be made via IPC. Secondly, Its not qemu/kvm that does the accouting. Its existing userspace code like top/snmp agents and clients! etc. that would require additional knowledge which thread is guest code. I personally like the approach Laurent has taken. Maybe it needs some polish and maybe we want an account_guest_time function, but in general I think he is doing the right thing.
