I was using fedora core 8 with xen 3.0.3 with one guest running windows
2003 with paravirtual drivers.
Network performance was close to native performance when DOMU or DOM0
was talking to a different physical host.
DOMO to DOMU is around 160 MB/sec
DOMU to DOM0 is very bad. (In the order of 4 MB/sec)
I was using iperf tool to test the network performance.
Here are the details from ipconfig.
