Ran into a situation recently where I needed to set up provider_vlan within OpenStack as well as configure the VLANs on the underlying hosts. This being the first time I’ve done this in Ubuntu it needs to be written down: apt-get update && apt-get install -y vlan modprobe 8021q vconfig add bond0 100 vconfig add

Having stumbled on the new /etc/resolv.conf methods of Ubuntu 12.04 a number of times, I hope this is useful for you as well. The contents of /etc/resolv.conf in Ubuntu are now controlled by “dns-nameservers #.#.#.#” in your /etc/network/interfaces file, like this: # The primary network interfaceauto eth0iface eth0 inet static address 10.0.191.100 netmask 255.255.255.0 network
