I have two Linux (Ubuntu 12.04) VM (running on KVM) that networked together using two Linux bridges as shown above. The network interfaces are Linux TAP devices.
The problem that I am facing is that when I ping from one host to another I see the following
root@ubuntu1204-template:~# ping 192.168.53.42
PING 192.168.53.42 (192.168.53.42) 56(84) bytes of data.
64 bytes from 192.168.53.42: icmp_req=1 ttl=64 time=1.12 ms
64 bytes from 192.168.53.42: icmp_req=1 ttl=63 time=1.13 ms (DUP!)
Any idea what am I doing wrong ?
I installed arping on the Linux vms and arping does not seem to exhibit this problem.
