My openvz kernel 2.6.16-026test015.2 publishes a permanent arp entry for my VE:
daves.isp2dial.com (69.60.124.123) at <from_interface> PERM PUB on eth0
My colo provider gives me 3 IPs, and publishes their own arp entries for my 3 IPs.
I have a problem where packets to the VEs are lost, intermittently throughout the day. By running tcpdump when the problem occurs, I can see the packets to the VEs are not reaching my ethernet card, while packets to the HN are.
I discussed this with the colo provider, and they don't think it's their problem. However, based on what the tcpdump reveals, I believe it is their problem. But since I can't get them to fix it, I need to work around the problem. I wonder if my published arp entries are confusing their router, since they publish their own arp entries.
Can I prevent the openvz kernel from publishing arp entries for the VEs? I don't need them, since the provider publishes an arp entry for each of my 3 IPs, and I want to experiment, to see if that might solve the problem.
