Will release note for stable-9, as not enough resources to work it. Fixing this is of interest though.

Comment by on triage call: affects all PCI devices and can lead to host freezing.

Does this affect Windows 7 and Linux guests?

What were the target use cases for guest UEFI, i.e why was the feature added to OpenXT? e.g. was it added to support Windows 10 guests with GPU passthrough? If PCI passthrough is dropped from UEFI guests, what will be the remaining target use cases for UEFI guest + OS combinations?
