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

transports need to be able to detect legacy-only devices (ATM balloon only) to use legacy path to drive them. Add a core API to do just that. The implementation just blacklists balloon: not too pretty, but let's not over-engineer. Signed-off-by: Michael S.

This patchset tries to go towards implementing both virtio-1 compliant and transitional virtio drivers in Linux. Branch available at git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux virtio-1 This is based on some old patches by Rusty to handle extended feature bits and endianness conversions. Thomas implemented the new virtio-ccw transport revision command, and I hacked up some
