Ok, so in this page


The 'PowerKVM' column doesn't mention libvirt and it links to this page


So I assumed that was referring to one of the stackforge drivers, and
that info on power-kvm-with-libvirt was simply missing entirely from
the wiki page.  So we'd need someone to update the new in-tree docs
with power-kvm-on-libvirt information from scratch.

If anyone still cares about the non-libvirt Power drivers they can
maintain a support matrix in stackforge for that.

The approach we've been trying to take with libvirt recently is that
each new platform we support (whether a new architecture, or new
libvirt hypervisor) would explicitly declare the minimum required
libvirt version for that platform.

eg the Parallels driver added


And in init_host()

        if (CONF.libvirt.virt_type == 'parallels' and
            not self._host.has_min_version(MIN_LIBVIRT_PARALLELS_VERSION)):

Given that Power support in libvirt requires some minimum version,
we'll need to add a MIN_LIBVIRT_POWER_KVM_VERSION and check for

These min version numbers aren't something I've attempted to capture
in the context of the feature matrix.
