{{project
|Project=Using Docker to deploy driver domains, service VMs, Mirage OS VMs, and friends - Can it be done?
|Date=2014-04-23
|Contact=Raised by Lars, but does not have the technical depth to really lead it (happy to take notes though)
|Desc=Docker is making a lot of waves in open source communities. There are really two functional aspects to Docker:
* Linux Containers as lightweight hypervisor (with all the security drawbacks)
* Application Containers as a packaging and deployment format - this part is really exciting as it is a ''gamechanger in application design, system deployment, and, critically, versioning''. Slides 1-15 of [http://www.slideshare.net/dotCloud/docker-intro-november] make this case quite compellingly.
What is not clear is how tightly the two are coupled and interdependent. I heard (but can't find references) that there are, or it is possible to write '''Docker Engines''' for other hypervisors. At least in theory.


Now, if you look at [http://www.slideshare.net/dotCloud/docker-intro-november/16 slide 16], you notice that the architecture diagram is very similar to a Xen based system with service domains, driver domains, and the likes of Mirage OS, OSv, ErlangOnXen (also see Voxoz which seem to be working on something similar), ... BUT: of course we have the added benefits of isolation and thus more security and the flexibility of running traditional fully fledged VMs with different Guest OS’es on the same host.
<br>

At least in theory, this should make it possible to use the deployment capabilities of Docker to deploy service domains, Mirage OS & friends. If this was possible and could be implemented easily we could be in for a winner. Aka getting all the benefits for the deployment part of Docker, while not suffering any of the drawbacks. And we could piggyback onto the Docker hype. Of course I don’t know whether this is technically feasible at all and how hard it would be to do this.

Topics

Please add topics you want to discuss in this section


Various process/infrastructure issues: xen-devel list traffic, devel IRC channel, personal repos, maintainerships

Date of insert: 2014-02-27; Verified: Not updated in 2020; GSoC: N/A
Technical contact: Lars Kurth
Mailing list/forum for project: xen-devel@
IRC channel for project: #xen-devel
Difficulty: N/A
Skills Needed: N/A
Description: I think we have a few issues:
  • Traffic on xen-devel has doubled in the last 2 years and is getting hard to handle. I would like to discuss different options and then make a proposal to the community
  • Reviews: seems we have a bottleneck of review capability in some areas - how to resolve?
  • We need a more open approach to devel IRC
  • We had a few requests for hosting team branches and personal repos : we need a document outlining when we would give someone a repo and how to request one
  • Maintainership : I believe there is a mismatch between our governance and what maintainers/committers expect. Maybe we can clarify
Outcomes: Draft proposal on developer lists, more open devel IRC and personal and team/integration repos


VirtIO and Xen

Date of insert: 2014-18-03; Verified: Not updated in 2020; GSoC: N/A
Technical contact: Daniel Kiper
Mailing list/forum for project: xen-devel@
IRC channel for project: #xen-devel
Difficulty: N/A
Skills Needed: N/A
Description: Discuss the technical issues related to make VirtIO work on Xen.
Outcomes: Use information for the VIRTIO-46


Merging PVH into HVM

Date of insert: 2014-03-27; Verified: Not updated in 2020; GSoC: Unknown
Technical contact: Tim Deegan
Mailing list/forum for project: xen-devel@
IRC channel for project: #xen-devel
Difficulty: Moderate
Skills Needed: Hypervisor internals
Description: I would like to make 'PVH' a special case of 'HVM' inside the hypervisor rather than a third VM type, removing some special cases and simplifying code. Much of that will be mechanical but there are some open questions around IO handling, CPUID etc.
Outcomes: A plan, and hopefully some code!


Incubation project proposals

Date of insert: 2014-03-28; Verified: Not updated in 2020; GSoC: N/A
Technical contact: Lars Kurth
Mailing list/forum for project: xen-devel@
IRC channel for project: #xen-devel
Difficulty: N/A
Skills Needed: N/A
Description: Two incubation project proposals are currently being worked on. I am still waiting for drafts:
  • One for Windows PV drivers
  • One for automotive / android (where the bulk may be userspace driver front-ends) and possibly some code/drivers specific to a few proprietary guest OS'es
As we are all there, it makes sense to review, propose changes and if we feel the proposals are good, to vote on them
Outcomes: Review (and vote on proposals), if they are ready in time


Libvirt and Xen integration / co-operation

Description: We would like to sync-up with other community members on libvirt + xen and to help make the default experience on Linux distributions better. References, see
Outcomes: Investigate designs, patches, approaches to improve Xen integration in Libvirt

Request Invite

As spaces at the Xen Project Hackathon are limited, we are asking attendees to request an invitation. If you did, you will be notified by email within 5 business days with instructions on how to confirm your invitation.

As last year, we will be asking for a small registration fee of $15. This fee will be given to a charity or open source organisation. You will need to cover your own travel, accommodation and other costs such as evening meals, etc. We do have limited travel stipends available for individuals who cannot afford to travel: please contact community dot manager at xen dot org if you need to make use of it.
