| | 10 | |
| | 11 | We have completed an initial research-grade implementation of sensor virtualization in Xen and released a |
| | 12 | technical report that applies the approach to Pan-Tilt-Zoom video cameras. The technical report can be found on |
| | 13 | the web at http://www.cs.umass.edu/publication/details.php?id=1575 and is also attached |
| | 14 | to this milestone report. As detailed in our quarterly status report we have faced challenges in applying the same |
| | 15 | techniques to the Raymarine radars in the ViSE testbed because their drivers do not operate by default inside of |
| | 16 | Xen’s domain-0 management domain. The problem affects other high-bandwidth I/O devices that use Xen, and |
| | 17 | is being actively worked on in the Xen community. As these problems are worked out, we have transitioned to |
| | 18 | using vservers as ViSE’s preferred virtualization technology, and developed vserver handlers for Orca. We are also |
| | 19 | porting VSense to work with vservers as well as with Xen; its modular design makes this port straightforward. Our |
| | 20 | demonstration at GEC5 in Seattle showed non-slivered VM access to radar control and data using vservers; once |
| | 21 | we complete our port of VSense we will be able to support slivered access. A more detailed description of these |
| | 22 | Xen, vservers, and sensors in ViSE is available in the quarter 2 quarterly report for ViSE. |
