Additional IP configuration
I then configured my network using the instructions in the linode library.
I'm using clean Debian 5 install so I placed the additional IP address and gateway into /etc/network/interfaces as eth0:0
I restarted networking and eth0:0 appears in the list underneath eth0
However I think I'm missing a step as the new interface doesn't appear to be doing anything. I can't ping from it, nor can I configure sshd to listen on the IP.
I've not got a firewall setup that's blocking it.
Can anyone suggest what I'm missing please?
Now to get the new IP working with an OpenVZ container…
You really shouldn't be double-virtualizing; since the minimum linode size is $20, it's not expensive to just get additional linodes if you want isolation.
It was just a learning exercise though, I'm not really into virtualisation, but I was bored at work the last few days and thought I'd see how far I could take it
For virtualization-under-virtualization purposes, I'd say OpenVZ is probably one of the better ways to go, thanks to its memory management shenanigans. Purely academic, though.
