Yes. As I've written: this enables us to enhance the interface later without the need to modify it first. >> In order to reuse the Xenstore directory creation already present in >> hw/xen/xen_devconfig.c move the related functions to >> hw/xen/xen_backend.c where they fit better. > > Why Xenstore and not QMP? We need to communicate with qemu only once instead of each time a device is added to the domain. Doing the communication via Xenstore is much simpler.
