[SOLVED] when pinging VM which is on the same host i get DUBs

[offerlam]

Hi all

3 prox nodes..
bond0 is balance-rr
vmbr0 is management
vmbr0.2 is vlan 2 for some VMS

As soon as i ping from two VMs on the same host i get DUP! alerts

^C
--- 192.168.253.4 ping statistics ---
13 packets transmitted, 13 received, +21 duplicates, 0% packet loss, time 11997ms
rtt min/avg/max/mdev = 0.141/0.174/0.267/0.035 ms

and it doesn't matter if they are on vmbr0 or bmvr0.2

has anyone experinced this?
