Hi guys,
I have the following configuration:
1. host is RHEL 5.5, 64bit with KVM (version that comes out of the box
with RHEL 5.5)
2. two guests:
2a: RHEL 5.5, 32bit,
2b: RHEL 4.5, 64bit
If I run iperf between host RHEL 5.5 and guest RHEL 5.5 inside the
virtual network subnet I get great

Thanks for the suggestion.
I tried with the netperf. I ran netserver on host and netperf on RHEL
5.5 and RHEL 4.5 guests. This are the results of 60 seconds long
tests:
RHEL 4.5 guest:
Throughput (10^6bits/sec) = 145.80
RHEL 5.5 guest:
Throughput (10^6bits/sec) = 3760.24
The results are really

At least it bought you
I tried with 'notsc divider=10' (since it's 64 bit guest), but the
results are the still same :-(. The guest is idle at the time of
testing. It has 2 CPU and 1024 MB RAM available.

Hmm, are you using e1000 or virtio for the 4.5 guest?
e1000 should
virtio...I think :-).
How could I confirm that?

Thank you a lot for the tip - you were right. The 5.5 guest is using
virtio, but 4.5 is not. So, this is the reason.
Adding model type='virtio' / to the config file unfortunately
doesn't help - the network card is not recognized by the guest. Do I
need to install something extra on the guest RHEL
