We will later use these to connect virtual disks and virtual network ports of our guest systems to real world storage and network. Here we first need to specify the physical device that needs to be exported by vdsdev to solarix guest domain and then we actually add the virtual disk thus created to the guest domain.


The vnts will later provide console connections to guest systems, very much like serial NTS’s do in the physical world. Bad magic number silaris disk label.
