MirageOS (http://openmirage.org) is a type-safe exokernel written in OCaml which generates highly specialised "appliance" VMs that run directly on Xen without requiring an intervening kernel. A MirageOS application typically runs via several communicating kernel instances on the cloud. Today these instances are difficult to manage; we would like to explore strategies for managing these distributed computations using common public cloud APIs such as those exposed by Amazon EC2 and Rackspace. |
||
These API bindings can be used to provide operating-system-level abstractions to the exokernels. For example, |
First we need to create pure OCaml API bindings for (e.g.) EC2 and Rackspace (purity is needed to ensure portability). These API bindings can then be used to provide operating-system-level abstractions to the exokernels. For example, a traditional VM might hotplug a vCPU; while a MirageOS application would request a "VM create" using the cloud API and "connect" the new instance to the existing network. We should be able to spin up 1000s of "CPUs" by using such APIs in a cluster environment. |
||
As well as helping Xen/Mirage, the public cloud API bindings will be very useful to other people in other contexts-- a nice side-effect. |

This page lists various Xen related development projects that can be picked up by anyone! If you're interesting in hacking Xen this is the place to start! Ready for the challenge?
To work on a project:
- Find a project that looks interesting (or a bug if you want to start with something simple)
- Send an email to xen-devel mailinglist and let us know you started working on a specific project.
- Post your ideas, questions, RFCs to xen-devel sooner than later so you can get comments and feedback.
- Send patches to xen-devel early for review so you can get feedback and be sure you're going into correct direction.
- Your work should be based on xen-unstable development tree, if it's Xen and/or tools related. After your patch has been merged to xen-unstable it can be backported to stable branches (Xen 4.2, Xen 4.1, etc).
- Your kernel related patches should be based on upstream kernel.org Linux git tree (latest version).
xen-devel mailinglist subscription and archives: http://lists.xensource.com/mailman/listinfo/xen-devel
Before to submit patches, please look at Submitting Xen Patches wiki page.
If you have new ideas, suggestions or development plans let us know and we'll update this list!
