[libvirt] [PATCH 00/10] libxl: PVHv2 support

This is a respin of my old PVHv1 patch[1], converted to PVHv2. Should the code use "PVH" name (as libxl does internally), or "PVHv2" as in many places in Xen documentation? I've chosen the former, but want to confirm it. Also, not sure about VIR_DOMAIN_OSTYPE_XENPVH (as discussed on PVHv1 patch) - while it will be messy in many cases, there is libxl_domain_build_info.u.{hvm,pv,pvh} which would be good to not mess up. Also, PVHv2 needs different kernel features than PV (CONFIG_XEN_PVH vs CONFIG_XEN_PV), so keeping the same VIR_DOMAIN_OSTYPE_XEN could be confusing. On the other hand, libxl_domain_build_info.u.pv is used in very few places (one section of libxlMakeDomBuildInfo), so guarding u.hvm access with VIR_DOMAIN_OSTYPE_HVM may be enough. For now I've reused VIR_DOMAIN_OSTYPE_XEN - in the driver itself, most of the code is the same as for PV. Since PVHv2 relies on features in newer Xen versions, I needed to convert also some older code. For example b_info->u.hvm.nested_hvm was deprecated in favor of b_info->nested_hvm. While the code do handle both old and new versions (obviously refusing PVHv2 if Xen is too old), this isn't the case for tests. How it should be handled, if at all? First few preparatory patches can be applied independently.
