Ah, libvirt does have support for specifying one machine type.

I mean that libvirt set default according to QEMU's default setting,
and management tools are dependent on this default setting without
users' specified setting.

I tried to change the default setting according to ppc64 platform
in libvirt, but it is not accepted.

I see.  Thanks for your suggestion. :)
