I think what i understood from you is two points: * You are trying to make grub boot your virtual machines. First you must understand grub is just a bootloader it has nothing to do with VMs. Virtual machines are managed by the kernel, qemu also is just helper. * You are trying to load external Grub module that isn't compiled with the one booting. If that is the case then this is unfortunetly not possible as i know, even if it does not stable (you already saw misaligment issue). The best way is to compile modules with at least grub source compiled. Those distributions maybe have there own fork and do the same, which is compiling with it and ship Grub with there modules.
