So I have the following problem. I would like to virtualise my pfsense in Proxmox and I try to do this on my "MSI MAG B550 TOMAHAWK" which has 2 network interfaces. The only problem is that when I try to integrate these 2 network interfaces and start the pfsense I get the following problem:

(The whole Proxmox server crashes...)

The Config of this VM looks as follows:

What I have already tried:

Starting pfsense without network interfaces = works
Starting the pfsense with only one of the two network interfaces = does not work
Integrating the network interfaces via the GUI = does not work
Integrating the network interfaces via the CLI = does not work

I really hope one of you can help me because I just can't find a solution, thank's in advance.
 
Hi,

I guess one network is in the IOMMU group of the SATA controller please send the output of this command.

Code:
find /sys/kernel/iommu_groups/ -type l
