Missing vhost_vsock kernel module in 5.15.0

[Dominic Schwarz]

[Impact]

$ sudo lxc launch images:ubuntu/focal ubuntu --vm

Creating ubuntu
Error: Failed instance creation: Failed creating instance record: Instance type "virtual-machine" is not supported on this server: vhost_vsock kernel module not loaded

[Fix]

Move module vhost_vsock from linux-modules-extra to linux-modules.

[Test Case]

See above.

[Where Problems Could Occur]

None expected, just moving a module between packages.

[Original Description]

Hey All,

I am new to the container, lxc, lxd stuff and I am at the end of my knowledge.
I have a fresh setup with a Raspberry PI 4 installed with Ubuntu 22.04 arm64.
So far everything works fine for containers but I can't get any vm to launch.

Seems like I am missing a kernel module, but I was not able to find or load it.
Already googled for it but was not able to find any matching problem with solution.

Additional Information:
>    ~  uname -r
> 5.15.0-1005-raspi

>    ~  dpkg -l | grep linux-image
> ii linux-image-5.15.0-1005-raspi 5.15.0-1005.5 arm64 Linux kernel image for version 5.15.0 on ARMv8 SMP

>    ~  modprobe vhost_vsock
> modprobe: FATAL: Module vhost_vsock not found in directory /lib/modules/5.15.0-1005-raspi
>    ~  lsmod | grep vsock

Status changed to 'Confirmed' because the bug affects multiple users.

[Juerg Haefliger (juergh)]

You probably need the extra package:
$ sudo apt install linux-modules-extra-raspi
$ sudo modprobe vhost_vsock

[Juerg Haefliger (juergh)]

We should move that module to linux-modules-raspi.

[Dominic Schwarz (dnic94)]

"sudo apt install linux-modules-extra-raspi" worked and installed the missing module.

Thanks!

This bug is awaiting verification that the linux-raspi/5.15.0-1012.14 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
