I am also having a similar issue. This is the first time I have looked at pass through as I’d upgraded to 6.10.3 and wanted to look at windows 11 on a VM and see how it performed, however I cannot for the life of me get my 1080ti to passthrough, have followed multiple guides, downloaded and edited the rom (removing the header), tried UEFI and legacy, tried editing xml to set multifunction etc.

Any ideas?
