Topics to Discuss, Code, Work on, ... at the Hackathon
Instructions
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
| Date of insert: 2014-04-08; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: David Scott, Daniel Berrange |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: N/A |
| Skills Needed: N/A |
| 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 |
|
QEMU and SeaBIOS regression testing
| Date of insert: 2014-04-08; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Konrad Rzeszutek Wilk |
| 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:
- We don't test or track how QEMU/SeaBIOS upstream works with Xen.
- We need a way to track so if somebody in the QEMU/SeaBIOS upstream breaks we can immediately notify them.
- We need a plan.
|
| Outcomes: Plan and roadmap |
|
KVP (Key value pair) in Linux with Xen
| Date of insert: 2014-04-08; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Konrad Rzeszutek Wilk |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: N/A |
| Skills Needed: N/A |
| Description: Microsoft drivers have a mechanism for host (and guest) to communicate IP addresses, and a family
of keys and values that can be exported in user-space. The user-space daemon (that every distro has nowadays)
can act on them (see in the Linux kernel tools/hv/hv_kvp_daemon.c). There are out-of-source tools that do
something similar (or better) in different products, but if we can piggyback on what is there and
expand to automatically work under Xen the better. |
| Outcomes: Plan |
|
NFV on Xen
| Date of insert: 2014-04-10; Verified: Not updated in 2020; GSoC: n/a |
| Technical contact: Joao Martins |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: N/A |
| Skills Needed: N/A |
| Description: A discussion on open issues regarding using Xen as an efficient NFV platform: fast packet I/O, network backend and our recent optimizations as part of developing ClickOS. We would further like to discuss how to go about mainstreaming our changes. |
| Outcomes: Discussion, Plan |
*  Jbeulich 07:12, 7 May 2014 (UTC) What is NFV? Please don't use acronyms unexplained unless it is clear that everybody knows them.

| Description: Figure out what we want in Xen 4.5. |
| Outcomes: Roadmap |

Using Docker to deploy driver domains, service VMs, Mirage OS VMs, and friends - Can it be done?
| Date of insert: 2014-04-23; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Raised by Lars, but does not have the technical depth to really lead it (happy to take notes though) |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: N/A |
| Skills Needed: N/A |
Description: 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 [1] 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 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.
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.
Maybe relevant References:

| Outcomes: Is it feasible to do this? Would anyone be interested? Are there next steps? |

Dealing with XSA-77 fallout
| Date of insert: 2014-05-07; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Jan Beulich |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: Moderate |
| Skills Needed: hypervisor internals |

| Outcomes: Determine set of people willing (and having time) to help. |

Further memory scalability
