Hi ,

We have been using qemu/kvm 0.12.5 (unchanged with stock kernel 2.6.32).

I just upgraded to qemu/kvm-1.0 and see noticable difference in packet I/O.

I want to understand the enhancements in 1.0 that leads to better performance.

Can you give me some pointers?

Off the bat I see new event code. From observation, I see that the
qemu-kvm process is
taking a whole lot less CPU.

Thanks
