We can add two virtio-gpu devices, but these devices can't interact with each other efficiently. They won't be able to share host blob resources without proper UUID implementation. > A new subsection should also be added for migration compatibility; see: > docs/devel/migration/main.rst Will update the docs, thanks. -- Best regards, Dmitry
