I disagree here. 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.
