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 results (> 4Gbit/sec). But if I run
iperf between guest RHEL 4.5 and either of the two RHELs 5.5 I get bad
network performance (around 140Mbit/sec).
Please try netperf, iperf known to be buggy and might consume cpu w/o
real justification
The configuration was made thru virtual-manager utility, nothing
special. I just added virtual network device to both guests.
Could you guys give me some tips on what should I check?
Regards,
Alex
