This reset may be necessary if a device driver is restarted or the device is handed off between (for example) SeaBIOS and the OS. Iff the vhost-user-scsi backend reports that it supports a new "reset device" feature, QEMU will send a VHOST_USER_RESET_DEVICE message when the guest resets the virtio device. Existing backends are unaffected. David
