Currently the 'solution' I've found is to edit Guix to remove the two instances of '--enable-kvm' which works somewhat, though it's slower as there's absolutely no acceleration. > It would be nice to have a --no-kvm switch, because I'd really like to > make use of Guix's nice VM features! We should probably also blacklist kvm on Libreboot machines too somehow, though this could also break it on non-Libreboot machines. I wonder if there's a way to query the BIOS to see if Libreboot is enabled? > PS: Apparently in future revisions of Libreboot, this will be fixed. > For now though... Oh really? I was under the impression this was broken due to microcode issues. Jookia.
