That wasn't obvious since it didn't mention libvirt in the heading as all the other libvirt columns did ! Sorry for not copying across your data then.

Ok, so in this page https://wiki.openstack.org/wiki/HypervisorSupportMatrix#Features The 'PowerKVM' column doesn't mention libvirt and it links to this page www.ibm.com/systems/power/software/linux/powerlinux/powerkvm 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 only thing I'd say about the pKVM support in the in-tree matrix is what > it's distro support is, i.e. if I have latest Fedora ppc64 will nova > libvirt/qemu work with it? How about Ubuntu? 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 MIN_LIBVIRT_PARALLELS_VERSION = (1, 2, 12) 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 that. These min version numbers aren't something I've attempted to capture in the context of the feature matrix.

The new as of last week PowerVM driver in stackforge [1] (and older PowerVC driver in stackforge [2]) are different and shouldn't be in the hypervisor support matrix wiki or the in-tree hypervisor support table. I can't wait for the day when there will be one power driver to rule them all and Frodo will have to destroy it in Mount Doom to avoid confusion. The only thing I'd say about the pKVM support in the in-tree matrix is what it's distro support is, i.e. if I have latest Fedora ppc64 will nova libvirt/qemu work with it? How about Ubuntu?
