These are minor robustness enhancements on top of v8 of the patchset [PATCH v8 00/50] linux: towards virtio-1 guest support http://mid.gmane.org/1417449619-24896-1-git-send-email-mst at redhat.com As that one seems stable and actually seems to work well for people, I'm not respinning it anymore. The main motivation is to prevent us accidentally supporting bad configurations, such as legacy

virtio 1.0 support for virtio-pci isn't ready yet. Therefore, this patchset doesn't make any functional changes. Instead, this simply refactors virtio-pci, splitting legacy device support code out to a separate file: virtio_pci_legacy.c For virtio 1.0, all that's left is to add virtio_pci_modern.c supporting get_features finalize_features get (config) set (config) get_status
