Cambridge, UK is located approximately 45 minutes North of London by train, with easy access by bus or train to [St. Pancras International - Eurostar (45m rail), London Stansted Airport (40m rail), London Heathrow Airport (LHR - 2h rail), London Gatwick Airport (LGW - 2h rail), Manchester Airport (MIA - 4h rail), London Luton Airport (1h25m bus). European attendees may consider '''Eurostar''' or '''Stansted Airport''' preferred routes due to short transit time to Cambridge and lower prices. |

|||
Visitors from the US or elsewhere will likely need to travel into one of London's major international airports, such as Heathrow (LHR) or Gatwick (LGW). With the exception of Luton Airport, rail offers a more convenient but more expensive route to Cambridge than bus, but will require using a combination of Heathrow Express/Tube and Rail (cost is approx. GBP 50-60). There are also several car service companies which arrange transfers from London Heathrow to Cambridge. The trip takes about 1.5-2 hours depending on the time of day. |

We are identifying suitable hotel options as we speak. We will select a mixture of hotels in the city centre and near the railway station. Do note, that the distance between city centre/railway station is |

* city centre : 3.7 miles (or 15-25 minutes by taxi) |
|||
* railway station : 2.7 miles (or 10 to 20 minutes by taxi) |
|||
=== Visa Invitation Letters === |
|||

We do have a number of concrete issues regarding governance that we need to discuss |
|||
* Project Leadership : will we go for a committee or project lead based approach, if the former how does it look |
|||
* Review roles in the community : clarify boundaries and responsibilities |
|||
* Decision making |
|||
** Clarify Lazy Consensus and scope it (when does, does it not apply) |
|||
** Clarify voting: scope, how +2 ... -2 and do votes have to be unanimous |
|||
* Add some criteria for roles lapsing (right now, people retain their status forever, unless they formally step down) |
|||
* Etc |

The Advisory Board has funded the creation of a quite sophisticated dashboard that should help both contribitors and reviewers of patches to better understand and manage code reviews within the project |
|||
* [https://kibana.bitergia.com/xen/app/kibana The dashboard] |
|||
What I wanted to do is |
|||
* Walk through the fundamentals |
|||
* Demo some core use-cases |
|||
* Get some feedback on next steps |
|||
* Do a bit of hands-on / interactive usage with interested people |

|Desc= |
|||
Discuss our multiple approaches to security and further goals: |
|||
* Deprivileged of QEMU - and the leftover TODO (PCI passthrough?) |
|||
* xSplice for patching hypervisor with XSA updates (should xen-security send out instructions on how to build binaries)? Make sure that the patches function nicely with xSplice tool? |
|||
* Instruction parser in Xen hypervisor? Existing approaches to depriv it - other means to lower the performance impact? |
|||
* Spell out limits of security support for qemu-xen and/or make QEMU an external dependency to Xen (also see [https://www.mail-archive.com/xen-devel@lists.xen.org/msg58158.html] |
|||
* Hypervisor defence in depth |

* Other security related improvements |

|Date=Feb 15 2016 |

|Contact=Konrad Rzeszutek Wilk |

Discuss "lost patches" that have floated around and haven't been addressed: |
|||
* TLB flushing on grant table unmmap? |
|||
* Memory scrubbing workers? |
|||
* Various "worker" functions we want to run from cpu_idle |
|||
* Other distros patches? |
|||
* per-cpu tasklets to lessen the tasklet spinlock contention |
|||
Some of these had been posted 2 years ago and while the authors are still |
|||
around they have a huge TODO list that. Brainstorm: |
|||
* Can we put all of those in a 'outstanding' patch queue? |
|||
* Could we put some of those on an GSOC or Outreachy internships? |
|||
* Other ideas? |

|Date=April 17 2016 |

|Contact=Rich Persaud, Ross Philipson, Eric Chanudet, Christopher Clark |
|||
|Desc=Discuss topics related to endpoint virtualization and security, including https://www.qubes-os.org and http://openxt.org: |
|||
* Can OpenXT provide test data or sample policies to help XSM to be enabled by default in upstream Xen? |
|||
* There are two independent PV USB efforts, one focused on Linux and an OpenXT implementation for Windows (used in production for several years) and Linux (relatively new). Can code be shared between them? If not, can a common USB test framework be used to validate both sets of drivers? |
|||
* OpenXT is moving closer to upstream OpenEmbedded for dom0, driver VMs and service VMs. What benefits does OpenEmbedded offer to Xen developers? |
|||
* How can Xen-based projects reuse common code for measured launch and measured upgrade? Implementations exist in XenServer, Qubes and OpenXT. |
|||
* Current status of interactions between libxl and garbage-collected languages like Ocaml & Haskell. Options for moving Ocaml/Haskell toolstacks to service VMs while keeping libxl in dom0. |
|||
* Display manager and input virtualization techniques for client use cases, including graphics composition and multi-touch. |
|||
* VHD encryption and blktap2/3. |
|||
* If uXen source code becomes public, is there Xen Project interest in maintaining uXen for use as a Xen Type-2 VMM in native Windows, and as a nested hypervisor within Windows guests on Xen? |
|||
* Is there work in the NFV telco community on standardized packaging of network driver/service VMs that could be used in client virtualization? |
|||
* Is there community interest in collaborating on the implementation of Virtual TPM and Secure Boot support for Xen Windows guests? Windows requires early boot (emulated) access to the Virtual TPM, before PV drivers can be loaded. |

I want to attend
Request an Invitation
In previous years we have requested for attendees to fill out a form and request an invitation. This was overly complicated, so we will revert back to a simpler approach. Please add your name to the list below.
- If you are a maintainer or otherwise a core member of the community, just add yourself to the Confirmed Attendees section stating your name and
- If you are not a maintainer add yourself the Request invitation. If your email address is not known in the Xen Community, please also add the name of your employer and send your e-mail address to community dot manager at xenproject dot org using "Request for Hackathon 2016 Invite" as subject line. This is important, such that we can e-mail more information to you. We will monitor this page and confirm whether we have space for you to attend.
You can use ...
* Name, Org
Or
{{Invite|Name|Org|IRC handle}}
Or to be able to co-ordinate travel and find people staying in the same place as you, ...
{{Invite|Name|Org|IRC handle|arrival date|leave date|lodging}}
IMPORTANT: The cut-off date for registrations is April 8th.
Please read the text in the warning box below: it contains more detailed instructions.

To edit this page and thus to Request an Invitation, you need to be added to the wiki's editors group. To be added to that group:
