Second NIC inside lxd

SeventhSon · August 17, 2018, 1:22am

I installed u18 in VirtualBox, added 2 network adapters, want to use second network card inside lxd container(s) directly. How to add physical network card into lxd?

First get VB to use exclusively the NIC, then in LXD use a nic device (lxc config device ... nic ...). With this LXD nic device, you get a single container to use exclusively the network card.

Could you please clarify what does it mean-“get VB use exclusively…”?
lxc config device add … nictype=? (ethernet or what?) I cand find full description of all parametres for “lxc config device add” command with full list of all the options.

For the first part see for example

The VB documentation should cover this as well.

For the second part, see

github.com

lxc/lxd/blob/master/doc/containers.md#type-nic

# Container configuration
## Properties
The following are direct container properties and can't be part of a profile:

 - `name`
 - `architecture`

Name is the container name and can only be changed by renaming the container.

Valid container names must:

 - Be between 1 and 63 characters long
 - Be made up exclusively of letters, numbers and dashes from the ASCII table
 - Not start with a digit or a dash
 - Not end with a dash

This requirement is so that the container name may properly be used in
DNS records, on the filesystem, in various security profiles as well as
the hostname of the container itself.

Use nictype=physical.
