OPNsense VM - BSD panic

[neoplayer]

Hi

New using Proxmox, I have been trying to run OPNsense in a VM, already tried both available bios and machine configuration but the BSD kernel always enters in panic mode. The closest I have gotten to finding the cause of the problem is this post in the lxc forum. But I have not been able to find a way to translate that set of instructions to Proxmox.

Last config file

boot: order=virtio0;ide2

Thanks in advance.

Hi, if I understand the linked thread correctly, you could try setting the CPU type for your VM to host (it is currently set to kvm64). See [1] for more details.

Thanks for the reply, tried what you suggested but unfortunately it did not solve the problem. The boot still stops at the same point.

Does it boot with CPU host and removing all the other flags ... flags=+pcid;+spec-ctrl;+ssbd

And without passthrough.

Without any flag other than host and without passthrough, still got the same bug. Reading this tutorial, I tried OPENsense 22.7, 22.1.2 and pfSense 2.6.0, with OPENsense both repeated the same bug, this contradicts that it was an issue with only FreeBSD 13.1 and with pfSense it get stuck in netmap queues/slots pfsense at 100% CPU in the VM. So I’m again at square one without any idea what’s happening. At least pfSense passes the CPU recognition, I’m going to debug the new ones, maybe it helps finding something that lets me pass the boot bug in OPENsense.

Well that tutorial is for hyper-v so a little bit different. What are the specs of your proxmox host? Obviously, many of us are running opnsense VMs and pfsense vms , I have been for a couple of years and just did a reinstall for 23.1 to confirm working before I updated my main opnsense router.

Currently using q35 and an efi disk but that's not required.

@neoplayer Does your proxmox host match up with those discussed here? https://forums.servethehome.com/ind...ke-proxmox-kvm-qemu-vm-guest-stability.38824/

@vesalius Hi! Sorry for not answering until today, I’m running Proxmox on an Intel i7-7700k. Didn’t have any luck making OPNsense pass the boot bug, but I was able to pass the bug of the pfSense VM, it didn't like having PCI Passthrough.

 

[fweber]

I reproduced the crash with the OPNsense ISO. For me, the culprit was memory hotplug -- could you try disabling it (via Options->Hotplug)?

For PCI passthrough, make sure to follow the admin guide [1].

@fweber thanks for the advice, it solved the problem, it's working perfectly right now.
