Migrated Container to VM: Network will not start at Boot

I recently migrated my Container VM, which is running Debian 12 (Bookworm), over to a (libvert?) VM using the documented method. The disk / volume copied without issue, and I was able to create the new VM.

When I boot the new VM, the following messages are visible from the Serial Console, and the VM does not come online:

rootfs: clean, 440235/63936000 files, 11041793/131046139 blocks

I googled this, and it appears to be a driver issue? The only two NICs available are VirtIO and Intel e1000 - how can I get the VM to load the network and boot properly?

Thank you for your help!

Logs attached, if this helps:

Edit: I should note this is on 25.04.2.5, I have not moved to 25.10 yet.

Looking deeper into this, it looks like there is a package that needs to be installed prior to migrating the Incus container over to the VM volume.

apt install wireless-regdb

I had a backup of my Incus image, so I restored from that, got it up and running (I had to un-set the pool and re-set it under Containers before it would let me import it), then installed the package.

When I boot now, I no longer get the platform regulatory.0, but I’m running into other issues. I’ll make a new post (below) as it’s new information.

I was able to resolve the initial issue, but the migrated VM is still not attaching to the network when I boot it. After doing the migration from Container to VM Zvol, then configuring the VM, when I boot the VM, I get the following:

Loading initial ramdisk ...

It’s still not connecting to the network. I have a VirtIO NIC configured, connected to br0. Removing it and re-adding the NIC has no change. Not sure what else I can try to get the VM to connect to the network?

I have the Incus image restored and running again, so if I need to make any changes pre-migration, I can do that and try migrating it (again).

Is there anyone with Debian familiarity or experience that can help me figure out why my VM won’t attach to the network at boot, despite being configured to do so?

This is moot, I wound up creating a new VM and migrating to that instead.
