Alan, the subject brought me to a question I have in mind for some time.
There seems to be a feature on z/VM's (4.4 to 5.2) which prevents the guests on the same VSWITCH to talk to eachother. This is what happens on our system with every VSWITCH I create. Every guest can't talk to other guests by default and I don't know how to enable it. Is there something I have to enable ?
