Not sure if this fits here, but I have an OpenVZ node currently running about 30 pure IPv6 containers. All of them are running fine, except for one of them.
This one container just doesn't work. If I ping it using an online IPv6 ping utility(I don't have IPv6 on my end), I get 100% packet loss.
If I do a ping6 google.com on the VPS, it stays blank for a really long while, but I haven't been patient enough to wait for any response, probably I'd get a timeout.
Alright, after waiting for like 5 minutes, I get this:
ping6 google.com
unknown host
Now all my other containers work absolutely fine, I get a latency of 5 ms from all other containers, but this one, don't know whats going wrong.
Here's the conf file of the container:
Code:
ONBOOT="yes"
CPUUNITS="1000"
CPUS="1"
CPULIMIT="50"
PRIVVMPAGES="32768"

VE_ROOT="/vz/root/$VEID"

OSTEMPLATE="centos-5.0-x86"

HOSTNAME="hostname"
IP_ADDRESS="The IPv6 addresses"
NAMESERVER="2001:4860:4860::8888 2001:4860:4860::8844"
Is there any problem in the config file anywhere? I don't see what could possibly be going wrong here.
Or if the config file's okay, any other suggestions/solutions?

The container config looks okay. Is the container running a virtual ethernet (veth) or virtual network (venet) configuration?

Would be helpful to see the output of ifconfig to determine whether the default route to the node is in place. Would also help to know any other troubleshooting you've done so I'm not repeating myself and taking up your time.

Is it the container config (thinking firewall) itself that is the problem?
