WhereTF does the IP come from?!?!
At the beginning, I added 192.168.200.112 to the VServer with --ipadd. But then I removed it with --ipdel and added a veth with --addif_net, as you can see in the config.
I grepped through everything in /etc and /vz but I simply can't find any reference to this **** IP.
Does anybody have an idea where the configured veth devices come from, including the IP?
Maybe I do not understand the concept yet...
Thank you,
divB
