Incus-agent in OpenWRT VM

tregubovav · January 8, 2025, 3:03am

I need prepare managed OpenWRT VM running in the Incus deployment.
I have built custom OpenWRT image, converted it and import to the Incus as VM, but I need some help to debug communication between Incus daemon and and incus-agent in the VM.

What is done:

Custom OpenWRT image with vsock.ko kernel module and custom network setup built and imported as incus VM.
VM run, incus-agent virtual disk mounted into the VM (mount -t 9p config /mnt)
incus-agent started with debug and verbose options (incus-agent -dv)
However, there is no evidence that the incus daemon can communicate with the incus-agent in this VM. The incus-agent output is below

./incus-agent -dv
INFO   [2025-01-08T02:35:21Z] Starting
INFO   [2025-01-08T02:35:21Z] Started vsock listener

It does not log any other messages even I execute any incus commands which require communication between incusd and incus-agent.

For example:

$ incus exec wrt-test
Error: VM agent isn't currently running

I would appreciate any help.

Hmm, I wonder if you’re maybe missing virtio-serial support too or if it’s just the specific /dev path being missing due to openwrt not using udev.

I forgot to mention this in the distrobuilder issue, but the agent uses /dev/virtio-ports/org.linuxcontainers.incus to notify the host system that an agent is running and can be reached over vsock.

Thank you Stéphane!

Yeah, OpenWRT builds very limited set of kernel modules. Do you mean the virtio_console.ko module is required to kick-off /dev/virtio-ports/org.linuxcontainers.incus ?

By the way, I made the last build without distrobuilder (simply converting OpenWRT image to qcow2 image). Distrobuilder do not allow to inject incus-agent to the OpenWRT now. Do I need to make the /dev/virtio-ports/org.linuxcontainers.incus symliynk before starting incus-agent?

P.S.
What additional modules are recommended? As I see the debian VM inculdes vmw_vsock_virtio_transport_common,vmw_vsock_virtio_transport modules as well.

I have just checked - the Virtio console feature has been compiled into the OpenWRT kernel I built.
Corresponded char devices exist:

crw-------    1 root     root      249,   1 Jan  8 02:24 /dev/vport5p1
crw-------    1 root     root      249,   2 Jan  8 02:24 /dev/vport5p2
crw-------    1 root     root      249,   3 Jan  8 02:24 /dev/vport5p3
crw-------    1 root     root      249,   4 Jan  8 02:24 /dev/vport5p4

I made a link:

lrwxrwxrwx    1 root     root            11 Jan  8 06:29 /dev/virtio-ports/org.linuxcontainers.incus -> ../vport5p1

and then started incus-agent again. Nothing has changed.
However, I see the error in the log:

daemon.err modprobe: failed to find a module named 9pnet_virtio

But this feature is compiled into the kernel as well.

Yeah, that part is fine, it’s just in the loader and it’s an optional step of it.

Any chance you can run incus-agent under strace to see what it’s doing?

Okay, it looks like it started and told Incus that much through the serial device…
Are you sure this ends up on the correct virtio serial device?

Normally Incus will connect to the incus-agent to push it some information once that write of STARTED has happened, but we’re not seeing that in your trace.

Can you do an incus export of your VM and ship me the file somewhere so I can poke at it here?

You can pick it up here.

VM architecture is aarch64.
I have removed eth0 device as I use custom networking setup. Please add eth0 device after importing the VM. You can get access to the console via ssh root@192.168.0.1. 192.168.0.1/24 assigned to the eth0 interface.

Much appreciate ,Stéphane, for your involvement!

I’m going to build x86_64 image to compare behavior with aarch64.
This needs some time.
