LXD SR-IOV Network "Unavailable"

LXD
1

I created an SR-IOV network but it shows up as unavailable and I can’t figure out why. I’m using a Mellanox Connect-X 6, and I have 16 VFs enabled, and they work fine when used via a profile, or as a directly attached instance device:

devices:
eth0:
nictype: sriov
parent: enp76s0np0
type: nic

But when I create an “sriov” network with the exact same parameters, the network is created successfully, but it shows up as “Unavailable”.

❯ lxc network create sriov-net --type=sriov parent=enp76s0np0
❯ lxc network show sriov-net
config:
parent: enp76s0np0
description: “”
name: sriov-net
type: sriov
used_by: []
managed: true
status: Unavailable
locations:

  • none

Is there something I’m doing wrong or anyway to debug why it’s unavailable when the NIC and VFs clearly work fine?

Please can you show output of ‘ip a’ on host?

In case it’s still relevant, here’s my output of ip addr:
