NACK, libvirt queries QEMU to determine the default machine type:
$ qemu-system-ppc64 -M '?'
Supported machines are:
none empty machine
ref405ep ref405ep
taihu taihu
bamboo bamboo
mac99 Mac99 based PowerMAC (default)
^^^^^^^^^
g3beige Heathrow based PowerMAC
prep PowerPC PREP platform
pseries pSeries Logical Partition (PAPR compliant)
virtex-ml507 Xilinx Virtex ML507 reference design
ppce500 generic paravirt e500 platform
mpc8544ds mpc8544ds
So if you want to change the default, then you should modify QEMU
upstream
