January 14, 20242 yr Hello Can anyone recall what is needed to be able to use passthrough devices, GPUs etc directly attached to a guest VM hypervisor such as vmware ESXi 8 running as a guest in UNRAID? I have created the VM, installed ESXi and managed to power on a nested VM. However, my Radeon GPU is greyed out and not available for passthrough. I know this is a niche set up but I thought it might be possible since you can nest esxi inside esxi and pass through IOMMU and vt-d for such a set up. The screenshot below is how ESXi sees the UNRAID IOMMU grouping at the 'guest' level. The AMDGPU is greyed out as you can see. I have added the following my ESXi VM xml. <hyperv> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> <vendor_id state='on' value='123456789ab'/> </hyperv> What else have I missed?
