So reboot mode; Can you explain which parts of this series are needed for reboot mode; I've managed to do a kexec based reboot on qemu with the current qemu - albeit with no vfio devices, my current understanding is that for doing reboot with vfio we just need some way of getting migrate to send the metadata associated with vfio devices if the guest is in S3. Is there something I'm missing and which you have in this series? Dave -- Dr. David Alan Gilbert / dgilbert@redhat.com / Manchester, UK
