[SOLVED] Weird problem: Lose all host WIRED network access when I pass through my WIFI/Bluetooth controller to a VM

[kevpatts]

Hey all,

I have proxmox on a machine with a single NIC and it's running pfsense and home assistant. All works well and all traffic is vLAN'd appropriately. the onboard wireless and bluetooth controller (Intel AX210) is unused as all wifi is being served via an OpenWRT AP.

I bought some bluetooth home automation devices so I decided to forward my bluetooth controller to the home assistant VM (vm 100) and start using them. BIG mistake!
I did:

lsusb | grep -i blu
 => Bus 003 Device 004: ID 8087:0032 Intel Corp. AX210 Bluetooth
qm set 100 -usb1 host=8087:0032

and then rebooted, only to find that ALL my networking was gone! Almost all of it anyway, it seemed that the pfsense VM was still accessible over WiFi on it's LAN interface. I couldn't even connect to it hardwired directly to a laptop using static IPs and the IP address it showed on the monitor console at the root login prompt!

Anyway I hooked up a keyboard and monitor, got into recovery mode, ran pmxcfs -l, found the config files in /etc/pve/nodes/, edited it and removed the usb1 line and rebooted and all was well again.

Any idea what happened? My theory is that the host NIC somehow got passed through to the VM along with the USB WiFi controller, but even this doesn't really make that much sense as I didn't pass it through to the pfsense VM!

Turned out to be a typo in the hardware address when I did the pm set command. I'm an idiot. Glad it's working now though.
