Comment 7 for bug 1936831

Thank you for your report. From the comments it has yet to be clarified whether there is a bug here, or missing support in libvirt/qemu for your particular requirements which might be considered a Wishlist feature request.

Either way this seems like "unusual end-user configurations or uncommon hardware" so I'm setting Importance to Low. Accordingly I wouldn't expect the Ubuntu Server Team to find the time to look into this soon, but feel free to use this bug to coordinate with others also affected.
