Dear Wolfgang, Erol and rest of WG members,
As new subscribers to the GridVirt WG mailing list, we would like to
introduce ourselves. We are part of the Distributed Systems Architecture
group (http://asds.dacya.ucm.es) at UCM. As you can see in our web page, we
are involved in different grid technology projects and infrastructures (as
well as in other OGF working and research groups). Our main technology
product is Gridway (http://www.GridWay.org) now a Globus project, a widely
used meta-scheduling technology for Globus based Grid.
We are highly interested in this working group as we have just started a new
project on virtualization and grid. The GridHypervisor
(http://www.GridHypervisor.org) project aims to enable the large-scale,
reliable, efficient and dynamic deployment and re-allocation of virtual
machines on physical resources belonging to different administrative
domains. As in other projects developed by the group, the technology will be
released as open-source software under the Apache license. The
GridHypervisor engine will be based on the GridWay technology for job
metascheduling in grid infrastructures. The main objective is to extend our
expertise and technologies on job metascheduling to VM metascheduling.
GridHypervisor will rely on Globus components, mainly on the Virtual
Workspaces Service (VWS).
Please let us know if you are meeting at OGF20, as we would like to
participate in the sessions.
Thank you for your time in the coordination of this WG,
Ignacio

Hi Paul,
thanks for pointing to the EGA reference model. I have briefly browsed
through the papers.
Here are some initial thoughts from my side.
Grid components:
I think that virtualization does not add new components. Rather it adds a
virtualized flavor in addition to the physical one ... as already pointed
out in the EGA reference model.
Accordingly, the DMTF SVPC working group has extended CIM to show virtual
and physical systems/resources side by side with associations between both
side.
Service Level Management:
System Virtualization definitely has an impact here. Monitoring, metering,
workload management needs to be aware of virtualization.
So far applications play a passive role w.r.t. virtualization. (This is
surely good to ensure compatibility.) Service level management is usually
done from outside. An inside-out view could provide new options, e.g. a
job asking for more CPU capacity.
Use cases
Indeed here I see additional use cases. The paper (2nd part) already lists
some "Future Use Cases".
By OGF20 we want to describe use cases which are specific to system
virtualization.

RE: Overlap?
Paul,
thank you for reaching out to our new GridVirt group. I characterize the
scope of this WG as a vertical thin slice of the virtualization space.
Simply stated, this thin slice has to do with grid infrastructures driving
virtual machines resources (whether it's memory quotas or "computons" or
infiniband queue pairs). Other worthy aspects of virtualization (e.g.,
network virtualization) are out of this group's scope (some other OGF
groups, like GHPN-RG and NM-WG, have gone or are going down this path).
So said, the EGA Ref Model can be quite useful to frame the lifecycle of a
VM. I very much like its being crisp and intuitive. Thus far, we have had
some loose interaction with the DMTF SVPC group around their modeling work
(see their presentation at our DC meeting). I expect that the GridVirt and
its nascent constituency will start off by building an appreciation of
which model can best serve the GridVirt WG.
What we do know today is that the GridVirt will abstain from rolling out
yet a new model.

Hi,
I just wanted to touch base with you guys re your scope and the potential
to perhaps leverage the work the Reference Model group is doing (see
https://forge.gridforum.org/sf/projects/rm-wg) The EGA Ref Model (which
we are in the process of refining in UML) describes virtualization quite a
bit, relates it to Grid (see
https://forge.gridforum.org/sf/docman/do/listDocuments/projects.rm-wg/docma…
) and describes the life cycles of all components (virtual and physical)
and how they relate to each other. It would seem that the model may
provide you with a useful basis for moving forward. I think it would be
good to discuss via email and perhaps to meet at OGF20 to discuss. I have
cc?ed Franco, now working here at eBay.

Paul
