Hello am using Qemu and KVM i learned you had too isolate a “IOMMU group” but a problem is that in the group there is more then just my GPU and i was wondering if thats a problem?

Trying too Duel.

Hi, i tried GPU Paththrough a couple of years ago (got it running but the guest gpu had graphic glitches, so i twist it back)

to you question:
Yes it’s a problem, because you would pass ALL the devices in the group to the vm, which left your host without access to nearly everything.

With luck, you can try to put the GPU in a different pci slot and hope that it will end up in a different immo group, or maybe you can try Bypassing the IOMMU groups (ACS override patch) but there you have to run a special patched kernel.

I would therefore recommend running a new Linux baremetal in a separate partition, as I did back then.
Much less effort and you won’t destroy your running system.
