Fuck, it says IOMMU disabled. But virtualization on Bios is enabled... BIOS update?

Hi Guis I wanted to pass through my tv tuner card (cine S2) But I get the following error, when I want to start up the VM: Error: unsupported configuration: host doesn't support VFIO pci passthrough.

How can i check if amd_iommu is enabled? Any other suggestions? BR Owel

I ask, because it is unclear for me, if only this script is slowed down by my application. or the parity check also? I read of scary out of memory errors. So my fear is, that when the script runs while everything else is stopped, it will come up with results , which will cause an error when the applications are running an parity starts ?! Can someone confirm that this fear is pointless?

Hi, I'm on v6b14 have two Dockers and two VMs running. Is it safe to run this script while these Application are running?
