Agenda item:  Domain n= ame service for nested virt and disaggregation

(text based on draft by Daniel Smith, who will speak to this ag= enda item)

If a futu= re, minimal "L0 Xen" hypervisor can be optimized for nested virtualization i= n greenfield deployments (i.e. no requirement to maintain existing hyperviso= r-guest interfaces), then PV driver mechanisms other than grants, events and= xenstore could be considered.  This was discussed in a Xen Summit 2019= design session:

For some OpenXT use cases, we a= re in the process of further disaggregating the platform.  We need a na= me service to enable the disaggregated service domains to discover the other= service domains with which they need to communicate.  Xenstore is not s= ufficient, as we would like to use Flask to control the data flow, as well a= s applying mandatory access control to service calls. 

We are reaching out to the Xen Community to= elicit input on approaches, such that we might be able to submit an upstrea= m RFC based on our early work:

- For a communication channel we are looking to leverage Argo, which is c= urrently in experimental status. Its predecessor (v4v) is already being used= in a similar fashion by Bromium uXen (https://github.com/openxt/uxen), which functions well across neste= d hypervisors.  uXen v4v includes a mechanism to control information fl= ow.

- An open question is h= ow to address the domains. Xen domain ids are reused and have no guarantee f= or uniqueness.  UUIDs are available and can provide better guarantees f= or uniqueness. Another approach is to use the name string which allows the a= bility for punctuation characters, eg. : or /, to create namespaced names fo= r the domains.
