Hello, I've noticed this strange networking behavior while running kvm-59 modules and qemu on a custom-compiled 2.6.24-rc5 kernel on x86_64 (2 x Opteron 2210). When I ping a VM from the host it's running on, I get the following result:
talithaA ~ # ping 10.0.1.1 PING 10.0.1.1 (10.0.1.1) 56(84) bytes of data. 64 bytes from 10.0.1.1: icmp_seq=1 ttl=64 time=850 ms 64 bytes from 10.0.1.1: icmp_seq=2 ttl=64 time=389 ms 64 bytes from 10.0.1.1: icmp_seq=3 ttl=64 time=0.353 ms 64 bytes from 10.0.1.1: icmp_seq=4 ttl=64 time=0.366 ms 64 bytes from 10.0.1.1: icmp_seq=5 ttl=64 time=0.361 ms 64 bytes from 10.0.1.1: icmp_seq=6 ttl=64 time=739 ms 64 bytes from 10.0.1.1: icmp_seq=7 ttl=64 time=740 ms 64 bytes from 10.0.1.1: icmp_seq=8 ttl=64 time=741 ms 64 bytes from 10.0.1.1: icmp_seq=9 ttl=64 time=1742 ms 64 bytes from 10.0.1.1: icmp_seq=10 ttl=64 time=731 ms 64 bytes from 10.0.1.1: icmp_seq=11 ttl=64 time=0.373 ms 64 bytes from 10.0.1.1: icmp_seq=12 ttl=64 time=0.380 ms 64 bytes from 10.0.1.1: icmp_seq=13 ttl=64 time=0.383 ms --- 10.0.1.1 ping statistics --- 14 packets transmitted, 13 received, 7% packet loss, time 13005ms rtt min/avg/max/mdev = 0.353/456.630/1742.288/509.780 ms, pipe 2 On the other hand, when I ping something on the network from the VM, I get: talithaA-v00 ~ # ping 172.16.1.1 PING 172.16.1.1 (172.16.1.1) 56(84) bytes of data. 64 bytes from 172.16.1.1: icmp_seq=1 ttl=64 time=1011 ms 64 bytes from 172.16.1.1: icmp_seq=2 ttl=64 time=2.81 ms 64 bytes from 172.16.1.1: icmp_seq=3 ttl=64 time=1000 ms 64 bytes from 172.16.1.1: icmp_seq=4 ttl=64 time=1.37 ms 64 bytes from 172.16.1.1: icmp_seq=5 ttl=64 time=1000 ms 64 bytes from 172.16.1.1: icmp_seq=6 ttl=64 time=1.37 ms 64 bytes from 172.16.1.1: icmp_seq=7 ttl=64 time=1000 ms 64 bytes from 172.16.1.1: icmp_seq=8 ttl=64 time=1.37 ms --- 172.16.1.1 ping statistics --- 9 packets transmitted, 8 received, 11% packet loss, time 8007ms rtt min/avg/max/mdev = 1.375/502.390/1011.591/500.668 ms, pipe 2 The two networks above (10.0.0.0/8 and 172.16.1.0/24) are on seperate Qemu VLANs. The hardware is a Dual Quad-Core Opteron 2210 server and I'm using the default (NE2000) virtual NICs. The host machines have no networking problems. If anyone could offer any advice, I would be most grateful. Thanks, Peter -- Peter Osuchowski Hosting Operations Engineer Turtol, LLC.
