Turns out that libvirt 3.9.0 hardcodes the boot partition to (hd0,msdos1) or allows overriding it completly using . I hacked together a patch that allows overring just the --root argument to grub-bhyve and updated the documentation: https://github.com/problame/libvirt/commit/5fd1265c05987d907d9f1d9913dbee83= 2a227889 Obviously, this does not meet quality standards and should not be merged as= is, but maybe spawn some discussion (if anyone is actually using bhyve + libvir= t).
