Yeah, I've been struggling quite a bit with this myself. Writing a custom version that runs in the guest means we have to create 1) extboot 2) input backdoor Or implement virtio in that custom version. That sounds like a pretty huge project. So I decided to go for the easy way for now and hopefully migrate to an in-guest version later. Alex
