Actually, <bootloader> is used to signify a helper program that
runs in host context to acquire a kernel + initrd image to boot
a guest from. So that's not the right element to be using here

If you want to provide a guest BIOS image, then you want to use
the <loader> element instead. IIUC, for UEFI, we use this with

  <loader readonly='yes' type='pflash'>/usr/share/OVMF/OVMF_CODE.fd</loader>
