I just didn't want it "lost". I don't always read git history's and others don't necessarily read code comments to get data such as this. Since it's not one of those every day tasks having it at least "somewhere" will hopefully help "someone". > I've applied this patch and build the qemu and rerun the regeneration of > capabilities and you are probably missing opengl virglrenderer and > usb-redir support in QEMU. > > I usually run "dnf builddep qemu" to ensure that I have all possible > dependencies and after that I build the QEMU, however this is not 100% > reproducible on a different system/OS/etc. Anyway, try to do it as well > in order to get as much as possible dependencies and reconfigure and > rebuild QEMU. OK did that and yep a few more things showed up.

Sure it could be, but I think that's overkill since I'm changing the DO_TEST as well. Still I can drop this since trying to keep things up to date in both places could be painful.
