The simplest way that I have found to accomplish this is with a simple bridge. I am assuming that you are using Ubuntu and have an Ethernet connection on the host. The bridge can easily be setup in /etc/network/ interfaces (there is tons of documentation). The resulting br0, or whatever you chose to call it, would then be used as the bridge device in containers config. You can than set up in the containers /etc/network/interfaces to have IP assigned by the router DHCP or assign your own static IP in the same subnet. Keep in mind that I have only done this with nested containers as I use a laptop primarily and wifi adds a level of complexity that I have not felt the need to deal with. But it did work perfectly in assigning IPs to the nested containers in the same subnet as the host container.

I'm really new to LXC/LXD as well as with macvlan setup, so bear with me. I'm having all kinds of trouble getting the macvlan setup to work on my Ubuntu 16.04 VM. The documentation isn't terribly clear, or at least it seems to be missing something that is keeping my containers from being accessible inside my office network directly. I'm hoping it's something simple, but as I've run out of good Google searches, I'm not sure what else to try. Here's my problem (and setup): I've been able to get containers of various distros running file with bridging, but I'd like to be able to access them as part of my LAN directly. The IP of the 16.04 host: 10.42.204.50 (gw 10.42.204.1) Now, I went through the docs to setup macvlans as this appeared to be the simplest (best?) method of setting up the containers to access my LAN. So, I ran dpkg-reconfigure lxd and removed the bridging. Then set the macvlan according to the docs <https://www.stgraber.org/2016/03/19/lxd-2-0-your-first-lxd-container-312/> : lxc profile device set default eth0 nictype macvlan lxc profile device set default eth0 parent ens160 The second command might not be correct, as the documentation doesn't specify precisely what the 'parent' is, though I believe it's the host interface name (in my case ens160). Regardless, this seems to have worked, at least partly because, when I launched an image of Ubuntu 15.10, the eth0 interface was correctly given a DHCP address from my LAN (10.42.204.153) and a default gateway (10.42.204.1). However, I cannot ping anything on my network from the container with a 'Destination Host Unreachable' message. IP forwarding is enabled, but I don't think I need that for this setup. The problem is, none of the docs say I need to do anything else to get macvlans working, which is why this is so frustrating. Is this just a case of I'm missing something the docs assume I have knowledge of? Or an actual problem. I'm no Linux slouch, I've been using them since the RH3 days, but macvlans are new to me, so is LXD. Any ideas? -- Mark Haney ::: Senior Systems Engineer *VIF* *International Education* P.O.
