Hello, These patches are an initial attempt at supporting hibernation for virtio drivers. The default configuration of event_index=on doesn't work; i.e. restore from a hibernated image only works if the devices have event_index support turned off. I have not yet dug into this, but is most likely due to some state not being sync'ed. This could be related to the hack that is patch 3. Each virtio driver has to be modif...
