Starting a VM without a network device works, the problem is that as soon as I add one (doesn't matter what kind), the system throws following error:

interface activation failed
kvm: -netdev type=tap,id=net0,ifname=tap135i0,script=/var/lib/qemu-server/pve-bridge,downscript=/var/lib/qemu-server/pve-bridgedown,vhost=on: network script /var/lib/qemu-server/pve-bridge failed with status 3328
start failed: QEMU exited with code 1

I made sure that the script is where the path points to but that's about everything I was able to come up with because I can't seem to find anything related to this matter.
I tried creating a new VM from scratch, problem still persists.
I tried the different device models that are available for selection (Virtio, Intel, Realtek), doesn't change anything.

I'm on PVE 8.1.4 and the same error exists on all three of my nodes.

Has someone stumbled upon this before?
Any help would be greatly appreciated. :)
 
I think if you provide the output of the following commands - it would help the community :
cat /etc/network/interfaces
ip a
qm config [vmid]
Can you start a VM without network device?
pveversion
Have you rebooted any of the servers and retried?
What type of NIC do you have?

Rebooting is not possible atm
 
When I spam the start button, the machines will eventually start with a working network connection but 9 times out of 10 it will throw the error mentioned above. Strange.

Though it's kinda working now, I'd nevertheless like to get to the bottom of this, so I'll keep this post open.

After you try to start a VM and receive a failure, run "journalctl -n 500" and examine the log for anything out of the ordinary.

Good luck

Found out that the culprit was actually the installed WatchGuard epdr software which blocked a script under /bin/, thanks for your help.
