Dear colleagues, i would like to run a vm with Ubuntu 14.04 server via incus. I was able to launch a vm and via the attached original ISO file boot and complete the install process. As to be expected I’m not getting any incus features because the incus agent is missing: the machine cannot be cleanly shut down from the supervisor, I cannot use the “shell” or “file” incus subcommands, etc. How would I go about enabling these features?
Hi!
Your best bet would be to generate the vm image for Incus yourself using distrobuilder
and the appropriate configuration file.
Ubuntu 14.04 (trusty
) is not supported anymore which means that you might have some difficulty finding the appropriate files. If that is the case, replace archive.ubuntu.com
with old-releases.ubuntu.com/ubuntu/
The last piece that you are missing, is the command-line parameters for distrobuilder
. You can have a look at https://jenkins.linuxcontainers.org/ which has the logs from the scripts that use distrobuilder
to generate the container/vm images found at http://images.linuxcontainers.org/
I am interested in the results of this investigation. Please report back how it all worked, especially the part about the old Ubuntu release.
You can install the agent manually through:
mount -t 9p config /mnt
cd /mnt
./install.sh
However this requires your Linux distribution:
- Supports 9pfs
- Supports vhost-vsock
- Uses systemd
The first point, you can workaround through the use of an extra disk using the agent:config
special driver.
The last point, you could workaround by making your own init scripts as needed.
The vhost-vsock part is likely the kicker for older distros as if that’s not supported, no amount of work will get the agent to function.
Thank you both, I will give it a try. I noticed that trusty was removed from distrobuilder in 2021, Drop Trusty that is EOL · lxc/lxc-ci@0143a6a · GitHub
I’ll experiment with bringing some of the configuration back and will report here.
If the agent won’t work, is there a way I can teach incus about connecting to the vm via ssh?
Sure. You can use cloud-init
to seed the VM with account details (such as your SSH public key).
You would need to use those images:debian/12/cloud
(note the cloud part) as those images have cloud-init
.
See the documentation on how to use cloud-init
or see How to customize Incus containers with cloud-init – Mi blog lah!
