Suricata unable to start (proxmox ?)

[toxic]

Hello.
Seems I have a similar issue as in this thread :https://forum.opnsense.org/index.php?topic=22942.0

I'm running the latest opnsense all updates done, inside a VM running on latest proxmox.
Trying to start suricata (Intrusion Detection) I get this in the logs :

Code: [Select]

opening devname netmap:vtnet0/R failed: Invalid argumentAnd the service stops.

I am using a "virtio (paravirtualized)" as the model of networking card for this VM.
I do not wish to pass the real underlying physical NIC (an intel E1000) as I configured it nicely in proxmox (was painful enough once) and I expect to upgrade the machine and the NIC in the future...

Do you believe it's a NIC issue with this paravirtualized model ?
I could choose a "VMWare vmxnet3" model easily in proxmox, but doing this the name of the interfaces in opnsense will change and I'm having issues to re-map them, especially since I have many VLANs and such.

Maybe someone can give me a trick to take a backup, manually rename vtnet0 and vtnet1 to whatever it's new name will be when it's a vmxnet3, that I could do, but without networking, how to pass the file to the opnsense VM, and how to reload the backup without networking...

Thanks in advance for any kind of help.
