I try to get working together vlan and bonding both for dom0 and domU. I
lost packets sent to dom0 while domU is OK.

Nightly stats for dom0:
52879 packets transmitted, 45293 received, 14% packet loss, time 52879599ms
rtt min/avg/max/mdev = 0.144/0.224/717.306/5.129 ms

Nightly stats for domU:
52952 packets transmitted, 52952 received, 0% packet loss, time 52952554ms
rtt min/avg/max/mdev = 0.157/0.209/3.166/0.048 ms

Alsow I ping dom0 on production server (which have no bonding) in same
rack and switch and see no packet drop. I see nothing strange in logs.

System config:
CentOS 5, Kernel 2.6.21, Xen 3.1.0

message this mornining and still did not receive it back.
