Unwanted network interfaces (virtual functions) in ubuntu-core-22

codingfreak · October 17, 2023, 3:32am

Hi All,

I am new to ubuntu-core and found following issue when I am playing with ubuntu-core-22 in a server.

I was adding and removing multiple VMs via LXD and after sometime it is observed that interface “enp113s0f0” is mapped with 63 virtual functions and physical interfaces which are not cleared off properly when the VMs are deleted (This is my assumption).

Is this expected behavior ?

Hi @codingfreak,

I have LXD running containers and VMs on my machine (Ubuntu Jammy), and I definitely don’t see virtual function being listed with ip link show. I think the first thing that needs to be done is establish who or what is creating those vf’s. You mentioned you’re running Ubuntu Core; could you provide steps to reproduce this behaviour? Thanks.

Hi @sergiodj

I do not have exact steps but this is what happened

I had a server which is provisioned with ubuntu-core-22 via MAAS-UI. Then I installed LXD and started adding and removing multiple VMs and Containers. Then I started observing the interfaces as shown in the logs.

Later on I rebooted the server and it comes up properly without these interfaces. After again adding/deleting VMs and containers using LXD observed the same behaviour.

By the way enp113s0f0 interface seems to be SRIOV capable according to MAAS
