Interfaces not showing in Dataplane KVM

@lastactionhero I usually make an additional admin-level account but I never enable root. I generally log in using the tnsr user.

Installing using virt-manager works. I have no issues performing a install and interfaces are present for use right away. No errors.

Installing via my kvm host, using virt-install seems to be where the issue is. Reviewing the domain XML's for any difference, I cannot find any difference. Very strange. If I find what's missing I'll update the post, but it works fine as a VM and virtio installing using virt-manager.

So, destiny decided that I should have received a support ticket with Netgate about this. (I was very surprised about it)

The support experience was very impressive and the engineer identified the issue really fast.

Proxmox uses QEMU, which integrates KVM.
It happens that the default CPU Type, "kvm64", doesn't have all the instruction extensions required, such as SSE 4.2, as mentioned here:
https://docs.netgate.com/tnsr/en/latest/platforms/kvm/#creating-a-vm

I've changed the VM to use CPU Type "Nehalem" and it worked out of the box, with the steps I've shared before.

Hope it helps others in the future :)

Thanks.

I too was able to resolve my issue. I apologize for hijacking this thread thinking it was similar underlying issue.

The difference between working and not working was when using virt-install, I need to use --cdrom for specifying the install ISO. Using --location ends up not working. While the installation completes, network interfaces do not. Virt-manager worked because it was using cdrom and not location.

Works:

sudo virt-install --cdrom tnsr.iso

Does not work:

sudo virt-install --location tnsr.iso
