This is version 2 of the modern virtio support for kvmtool. Since v1 [1]: * Repaired vhost-net for pci-modern, by adding patches 4 and 5 * Added patch 6 that extends the feature fields and simplifies modern features handling * Added patch 12, a small cleanup Since vsock and scsi devices have been broken for a while, this series doesn't attempt to make them work but I have another series [2] to fix the vhost support, that I will send later.
