So you really mean to run Qemu inside Oracle VM? For KVM, the module
needs to run on host kernel.
If you are in the VM kernel already, KVM does not provide you with
hardware acceleration.

Hi Folks,
We have some fundamental questions on vhost-net performance.
we are testing kvm network I/O performance by connecting two
server class machines back to back
(cisco UCS boxes with 32GB memory and 24 cores).
We tested with and without vhost-net.
Qemu version 0.15
latest libvirt
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
Side note: I am not using vhost-net yet. I am reading from the blogs
that vhost-net gives much better performance.
I am putting another system up with vhost-net support to measure this.
Appreciate the pointers for previous question.

Hi,
We are currently using 2.6.32 kernel and looks like the vhost-net
feature came in 2.6.34.
Using Qemu based I/O seems to be too taxing on our system (network I/O
is the primary application).
We are taking the vhost/net.c code from 2.6.34 kernel, but comparing
to 3.2 kernel, the new code
