Hi,
I'm trying to get Xen running on 2 different systems and have massive packet 
losts independ from the system I use!
This are the results from an UDP-Benchmark-Test from an Xen-Server to another 
one. As you make notice, the
sending packets have a lost rate from &gt; 80% up to 99%. What the hell is 
going on? I have no ideas.
If I boot my 2 Xen-Servers with the normal kernel (without Xen) then all is 
running wonderfull and I have no packet lost! Therefore it must be a Xen 
problem!
NETIO - Network Throughput Benchmark, Version 1.23
