Connecting LXC to the host network

There are three main modes of connecting LXC containers to the host network:

• Using a physical network interface on the host OS, which requires one physical interface on the host for each container

• Using a virtual interface connected to the host software bridge using NAT

• Sharing the same network namespace as the host, using the host network device in the container

The container configuration file provides the lxc.network.type option as we saw earlier in Table 5.1. Let's take a look at the available parameters for that configuration option:

Parameter	Description
none	The container will share the host's network namespace.
empty	LXC will create only the loopback interface.
veth	A virtual interface is created on the host and connected to interface inside the container's network namespace.
vlan	Creates a VLAN interface linked to the device specified with lxc.network.link. The VLAN ID is specified with the lxc.network.vlan.id option.
macvlan	Allows a single...
