Re: [Xen-devel] Q: How to find own domid or uuid from domU?

If it's only management tools looking to obtain info about other

Is there any reason a domain needs to know its *own* uuid?

It's management tools looking to obtain info about their own domain.

Consider a network-enabled stat-gathering, managing, or monitoring
tool running on domU.  It wants to uniquely identify itself to the
peer.  IP or MAC can work in some environments, but in others they're
ephemeral.  UUID would be much better.  It's the only thing that known
never to change, isn't it?

Ok makes sense.

Adding a new op to the version hypercall will be fine.
