Ok, I did some quick and dirty testing. I set up a CentOS 5 server
with kvm and vde. On that host I installed Ubuntu 8.04 server. I then
run iperf from my desktop box to the ubuntu guest. The speeds were 80

I then redid the host machine and installed KVM without VDE installed
the same Ubuntu 8.04 server and ran the iperf test again. I was able
to get 94.0 Mbits/sec

The preformace hit is not that bad, in fact it is basically nothing in
the scheme of things. I don't understand quite how it would solve the
network issues that I am running into, could you explain your ideas on
