Hi James, If the OS can detect the card then it can be passed-through. There's a very nice article on how to achieve that: https://lab.piszki.pl/cloudstack-kvm-and-running-vm-with-vgpu/
Let me know if it works for you, am quite curious about it.

Hi all, we have added some Ubuntu 20.04 hosts which have an AMD ATI Radeon Pro WX 5100 fitted inside. We would like to passthrough the Radeon PCI device to KVM guests. IOMMU has been setup correctly and the Radeon card is showing as a VFIO-PCI device. lspci -k shows: d9:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon Pro WX 5100] Subsystem: Advanced Micro Devices, Inc.

Is support for AMD coming? Has anyone managed to get AMD passthrough working? Does anything need to be specified perhaps in: /etc/cloudstack/agent/agent.properties ??? Thanks, Jim
