You don't mention what your OS is ?  Some OS vendors patch QEMU
to have different machine types than upstream QEMU provides, and
I guess that's what you've hit.

If you look in your libvirt XML 'virsh dumpxml $GUESTNAME' you'll
see a machine type listed - probably "pc-$SOMETHING" or "q35-$SOMETHING".

If you simply delete the "-$SOMETHING" part to leave just "pc" or
just "q35", then libvirt will expand the machine type into the
latest one available with your self-built QEMU
