Hi everybody,

In case of multithread TCG what is the best way to handle qemu_global_mutex?
It shouldn't need any changes I think. You're basically bringing
TCG into line with what KVM already has -- one thread per guest
CPU; and qemu_global_mutex already works fine in that model.

Hi Peter,

Thanks for your reply.
True that makes sense, I still think we need to synchronize vcpu when they exit?
