Release Notes

I. Intro and Description

VCL, Virtual Computing Lab. The VCL can be many things, first and foremost it is an open-source system used to dynamically provision and broker remote access to a dedicated compute environment for an end-user. The provisioned computers are typically housed in a data center and may be physical blade servers, traditional rack mounted servers, or virtual machines. VCL can also broker access to standalone machines such as a lab computers on a university campus.

...

The release supports provisioning nodes using xCAT 1.3, xCAT 2.x, VMWare Server 1.x, VMWare Server 2.x, VMWare ESX 3.5, and VMWare ESXi with both purchased licenses and free licenses.

II. VCL Roadmap

VCL 2.2.1 (this release)

• removed frontend dependency on jpgraph
• remove any access control that is hard coded in frontend
• added support for VirtualBox hypervisor
• many bug fixes and improvements to VMWare support

...

With each release, we'll be working toward making VCL easier to install. As part of our move to development at the Apache Software Foundation, it is an obvious goal to create a community of users and more developers around VCL. Bringing in more developers should become easier as VCL becomes easier to install.

III. Getting Involved in the ASF VCL Community

There are five ways to become involved in the ASF VCL community.

...

• If you are interested in contributing something to the project, please discuss it on the vcl-dev list BEFORE starting work on it. This allows the community to be involved in decisions and allows current developers to provide some guidance.

IV. How to Submit Bugs and Feature Requests

If you find a bug, please submit a bug report to our JIRA bug tracking system at http://issues.apache.org/jira/browse/VCL (you will need to set up an account there if you haven't already done so - it's free to anyone). Also, we would appreciate it if you mentioned that you filed a bug on the vcl-dev list to make sure we don't miss it.

...

After you have created a JIRA issue, you have the option to vote on it to help us know how to prioritize issues. You can also "watch" the issue to see when activity related to it is submitted.
