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?
