Aha I didn't know about that one. I don't think it's nitpicking, that's
a good suggestion, thank you.

Sure.

Yeah I will. That was the option used by some scripts here but it
doesn't seem to work for me here, whereas the default IIRC sungem
does get networking up. Could be a QEMU regression so I was meaning
to try a bisect.

Thanks for the feedback on these. I'll leave the MacOS and AIX ones
out of the next ppc PR so there is more time for thought and
discussion about them.

Thanks,
Nick
