Cédric already posted information for these, thanks.
Cédric, could you also send me a patch to MAINTAINERS to add yourself
as a maintainer of the powernv machine type (I'm fine remaining
co-maintainer).

I'm hoping Hervé can answer this one.

I believe Zoltan should be able to answer this one.

I hope Edgar can answer this one, I have no idea.

Lots of ways to boot this. Modern RHEL, CentOS, Fedora, Debian or
Ubuntu for ppc64 should work. kvm-unit-tests also supports this
machine. Any other details you want?
This is actively maintained and tested downstream by Red Hat, possibly
amongst others.

I receive and merge occasional fixes for this, but I don't really know
how to use it. Alex Graf or Greg Kurz might know a bit more.

Mark, can you answer these ones.

I don't know much about these, though I receive and apply patches
occasionally, so presumably they work for someone. Alex Graf might
know more.
