So I was running on 2.6.18-53.1.4.el5.028stab053.4PAE up until 2.6.18-53.1.6.el5.028stab053.6PAE had been made available. After switching over, I found that the HN and the VEs all still had IPv6 configured and running on them, however even with the default route in place, they couldn't get out. I could ping the gateway, but anything beyond was "no route to host". I rebooted back into 53.4PAE and everything worked again.
I meant to bring this up earlier after the kernel had been released but have been busy. I'm still running on 53.4PAE because IPv6 connectivity is a requirement for my system.

Yes, otherwise I couldn't have gotten into the machine, as it is remote.
Quote: | you ping gateway from VE only, or ipv6 network in HN also didn't work?
|
I could ping the ipv6 gateway from the HN and VE.
I couldn't get beyond the ipv6 gateway when tying to reach www.kame.net, from either HN or VE.
Quote: | gateway on another machine?

The gateway address resides on a router upstream from the machine. The network topology is: server -> Cisco L2 switch -> Foundry Netiron router.
Obviously there is no issue with the switch or routers upstream of the server, since simply changing the kernel fixes the issue.
Quote: | what network card used?

Broadcom
eth0: Tigon3 [partno(BCM95704A6) rev 2100 PHY(5704)] (PCIX:133MHz:64-bit) 10/100/1000Base-T
No vlan used on the server. The only vlan in use is between the router and switch.

I verified that it was set correctly, however that setting shouldn't affect routing for eth0 on the HN, only the ipv6 connectivity for the VEs, correct?
