I had to go all the way down to 7.8.0 to apply these (somewhere mid October). I believe libvirt is not the only project that mandates this. I've uploaded these patches to my gitlab: https://gitlab.com/MichalPrivoznik/libvirt/-/tree/sgx You'll find 'fixup' commits there which cover some of the points I am raising. Might be worth looking at it. I'll keep the branch there for a while. Michal
