[http://lxc.sourceforge.net/ LXC] (Linux Containers) * Support in mainline kernel * relevant options enabled in default Ubuntu kernel * tap-style virtual interfaces, can be bridged * interfaces * userspace tool * raw syscalls * libvirt == Networking == Fully isolated kernel-level networking. Fits into VDE framework with bridging: [[Image(lxc_networking.png)]] Architecture alternatives: * one bridge per VLAN (pictured above) * reduces number of bridges * VLAN becomes hub-style broadcast domain (con) * one bridge per node * switch-style broadcast domain thanks to VDE switch * same interface as other vnodes * one bridge, one vde_plug2tap process, and one tap interface per vnode (con)
