Re: [libvirt PATCH] qemu: format 'ramfb' attribute for mediated devices

It's possible to use ramfb as the boot display of an assigned vgpu device. This was introduced in 4b95738c, but unfortunately the attribute was not formatted into the xml output for such a device. This patch fixes that oversight and adds a xml2xml test to verify proper behavior. https://bugzilla.redhat.com/show_bug.cgi?id=1847791 Signed-off-by: Jonathon Jongsma <jjongsma(a)redhat.com&gt; ---
