`multipass networks` command

Same issue in my case, running on Pop!_OS 20.04:

  • as the instance does not have access to the Internet (DNS resolution works fine, though)
  • tried also to use this LXD, as being Linux specific (and only? option)

So, installed LXD:

$ sudo snap install lxd
[sudo] password for dxps: 
lxd 4.15 from Canonical✓ installed
$ 
$ sudo lxd init
Would you like to use LXD clustering? (yes/no) [default=no]: 
Do you want to configure a new storage pool? (yes/no) [default=yes]: no
Would you like to connect to a MAAS server? (yes/no) [default=no]: 
Would you like to create a new local network bridge? (yes/no) [default=yes]: 
What should the new bridge be called? [default=lxdbr0]: 
What IPv4 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: 
What IPv6 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: 
Would you like the LXD server to be available over the network? (yes/no) [default=no]: 
Would you like stale cached images to be updated automatically? (yes/no) [default=yes] 
Would you like a YAML "lxd init" preseed to be printed? (yes/no) [default=no]: 
$ 
$ sudo multipass set local.driver=lxd
$ 
$ sudo snap connect multipass:lxd lxd
$ 

And then:

$ sudo multipass set local.driver=lxd
$ sudo snap connect multipass:lxd lxd

Unfortunately, the result is the same:

$ multipass networks
networks failed: LXD object not found
$

The same error is thrown when trying to multipass lauch-ing with the --network flag.

Any idea, please?
Thanks.

Hi @dxps, could you please open a bug report and fill in the details here? What does lxc network list say? Thank you.

Hi folks,

I wrote down the steps to get it working because maybe some of you are having the same problem.

Instructions for running multipass on a bridge network

I would be happy to help you.

Hi folks,

I have created a new operating procedure that runs in Multipass 1.7.0.

If you have any suggestions for this document, feedback is welcome.

It works for me on Ubuntu 20.04.4 LTS Desktop, but it fails on Ubuntu 22.04.1 LTS Server:

$ multipass launch --network eno1 
Multipass needs to create a bridge to connect to eno1.                          
This will temporarily disrupt connectivity on that interface.

Do you want to continue (yes/no)? yes
launch failed: Could not create bridge. Could not reach remote D-Bus object: The name org.freedesktop.NetworkManager was not provided by any .service files

and after installation of network-manager:

$ multipass launch --network eno1 
Multipass needs to create a bridge to connect to eno1.                          
This will temporarily disrupt connectivity on that interface.

Do you want to continue (yes/no)? yes
launch failed: Could not create bridge. Failed DBus call. (Service: org.freedesktop.NetworkManager; Object: /org/freedesktop/NetworkManager; Interface: org.freedesktop.NetworkManager; Method: ActivateConnection): No suitable device found for this connection (device br-eno1 not available because profile is not compatible with software device (mismatching interface name)).

With:

$ multipass networks
Name     Type      Description
docker0  bridge    Network bridge
eno1     ethernet  Ethernet device
mpbr0    bridge    Network bridge for Multipass

$ snap list multipass lxd
Name       Version        Rev    Tracking       Publisher   Notes
lxd        5.0.0-b0287c1  22923  5.0/stable/…   canonical✓  -
multipass  1.10.1         7689   latest/stable  canonical✓  -

I guess it’s related to that Ubuntu server uses systemd-networkd and not network-manager to control the network interfaces by default. And just installing network-manager does not enable it.
