Topics
Xen on ARM "Portathon"
| Date of insert: 12/03/2013; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Ian Campbell |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: Not too hard if you are familiar with the hardware and have Linux running |
| Skills Needed: Mostly C |
Description: Xen on ARM has reached the point where it is becoming reasonable to port it to a wider set of hardware. The idea of this session would be to take advantage of the presence of the Xen on ARM developers to port Xen to your hardware. In order to participate you will need:
- Access to a hardware platform which supports the ARM virtualisation extension which you wish to port Xen to.
- Could be local access if hardware is portable, otherwise remote serial and power control will be required
- Software models could also be considered
- An existing functioning port of Linux >3.8 to the platform
- Access to datasheets and/or extensive knowledge of the hardware platform
|
| Outcomes: Xen running on some new ARM platforms |
|
Update toolstacks to make use of libxl and/or xl
| Date of insert: 12/03/2013; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Ian Campbell |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: Depends on the complexity of the toolstack which needs modifying |
| Skills Needed: Some C, perhaps knowledge of the C bindings for the language which the toolstack uses. |
| Description: There are various higher-level toolstacks which make direct use of the xend interfaces (either through xm, sxp or XML/RPC). This project offers an opportunity to collaborate on porting toolstacks to use xl or other modern toolstack interfaces.
This project also covers those who wish to use libxl directly to implement their own toolstack or to port an existing toolstack from other lower-level interface (such as libxc) to libxl.
It is expected that participants will be familiar with the internals of the toolstack the wish to port to libxl/xl |
| Outcomes: More toolstacks using xl or libxl. |
|
VMFUNC, grant table operations, Intel QuickData engines
| Date of insert: 12/03/2013; 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: Need to read dense Intel docs. |
| Skills Needed: Wielding a sharpie. |
| Description: Intel has released a new VMX type operations that allows one guest to switch in another guest page-tables. We could utilize this for a backend guest to
switch in the page-tables that the frontend has provided via the ring. Along with the Intel QuickData engine we could keep the contents of these
pages (aka grefs) in the LLC. This is all handwaving at this point and I am hoping to brain-storm the problem and issues we will face. |
| Outcomes: Faster performance. |
|
Close Security Vulnerability Process Changes as well as discuss possible mods to the Governance Process
| Date of insert: 29/03/2013; 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: We should take the opportunity of core developers present to close down the proposed Security Vulnerability Process discussion as much as possible. Also, I wanted to discuss whether we can be a little bit more open about membership of the Security Response team (i.e. who is on it, and what the process/mechanism is of becoming a member of the team). And maybe any other security related questions.
I would also like to take the opportunity of discussing possible changes to the governance process. |
| Outcomes: Not specified, project outcomes |
|
Update OpenNebula integration to use latest Xen version
| Date of insert: 11/04/2013; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Javi Fontan |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: Depends on how much code we can reuse from previous integration |
| Skills Needed: Bash and Ruby knowledge and perhaps some C++ to change deployment file generation. |
| Description: OpenNebula is a Cloud Computing Manager that has drivers to create and manage Xen VMs. The integration with Xen was done some time ago for version 3.x and even we are continuously bug fixing and updating it still uses xm command to perform all management. We want to change the way of interacting with Xen to new versions (libxl, xl) and explore new features that can be added. |
| Outcomes: OpenNebula is properly integrated with Xen 4.x |
|
Port Synnefo to Xen
| Date of insert: 18/04/2013; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Constantinos Venetsanopoulos |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: Not too hard if you are familiar with Ganeti internals wrt the hypervisor layer |
| Skills Needed: Python, knowledge of Ganeti internals and Xen networking |
| Description: Synnefo is open source cloud software. It is a complete cloud stack (Compute/Network/Storage/Image/Identity Service) with a unique design approach that keeps clear separation between the cloud and cluster layers. It exposes the OpenStack REST APIs to the outside world, but in the same time uses Ganeti for the low-level VM management part. Currently, Synnefo supports only KVM, but because of the fact that it uses Ganeti at the backend, it is easy to port it to also use Xen as the underlying hypervisor. The only part of Synnefo that needs to be ported is the networking component (snf-network). However, for this to happen, we first need to implement the corresponding feature in Ganeti, to be able to run a custom script with information in its environment every time a vif gets created. |
| Outcomes: Synnefo running with Xen as the underlying hypervisor |
|
Export information about the shutdown (or reboot) reason for an instance.
| Date of insert: 19/04/2013; Verified: Not updated in 2020; GSoC: N/A |
| Technical contact: Michele Tartara |
| Mailing list/forum for project: xen-devel@ |
| IRC channel for project: #xen-devel |
| Difficulty: ? |
| Skills Needed: C and some knowledge of the codebase to find the proper place where to implement this |
| Description: Currently, Xen is aware of the reason why an instance was shutdown or rebooted (as described in http://zhigang.org/wiki/XenVirtualMachineShutdown), but it only makes it externally available in its log file, which is extremely long and therefore inefficient to parse. External tools can be interested in obtaining such information. This project aims to find and implement the proper way to export it (for example, by invoking an optional external callback script and passing the name of the instance, the shutdown reason and some other useful information, such as the timestamp). A partial implementation was already proposed previously in http://lists.xen.org/archives/html/xen-devel/2012-03/msg02602.html and can be used as a starting point. |
| Outcomes: Xen provides externally the state change reason of instances. |
