Hey guys,<br><br>I have bunch of questions about virtualization. Please bear w/ me as I am a Linux novice, with only 9 months an Ubuntu user. Alot of my questions about virtualizing the XO image may be quite elementary.<br>
<br>As you may recall, I earlier posted an idea about a new distro that OLPC developers could use to develop for the XO on conventional hardware. You guys correctly disabused me of that idea. A package is the way to go. Marco noted that Sugar is still in too much flux to provide a stable development environment. I think developers here in Nepal and elsewhere need a learning environment to so they can eventually write great activities for the XO. We can encourage developers to learn Python and GTK but nothing will motivate them like seeing their activity run w/ in the Sugar interface - even if their activity breaks in two weeks or two days.
<br><br>For the foreseeable future, we won't be able to hand an XO to all of the interested developers. We would like to hand them some kind of package that lets them work on activity development without getting stuck in the details of qemu configuration.
<br><br>My friend Jon Sequeira and I discussed this issue and we decided that novice Sugar developers will need a virtualization package that will mimic the hardware as closely as possible. We put some of our ideas down on OLPC Nepal's wiki -- which should be migrated to the main olpc wiki shortly.
<br><a href="http://wiki.olpcnepal.org/index.php?title=Kantipur">http://wiki.olpcnepal.org/index.php?title=Kantipur</a><br><br>We would like to preconfigure qemu, bochs, vmware player or another emulator to mimic the XO hardware as closely as possible. We're thinking of how to emulate the mesh networking, sound, videocamera, and performance constraints. What would be the best way to accomplish this? According to Ivan, we can simply load Csound libraries and use qemu's TAP network interface for the sound and networking features. I've read up on that on the "Troubleshooting QEMU" wiki page.
<br><br><br><ul><li>Mimicking the videocamera -- perhaps we could just read in a video or image file w/ a simple file read?<br></li><li>Audio input -- How could we have multiple virtual microphones on the same machine? Say we want to stream audio between two qemu XO instances on the same machine.
</li></ul>We would like to distribute the emulator and olpc-specific configuration files to developers here in Nepal. Ideally we would like to package it w/ reference docs for Python, GTK, Squeak, etc. + a development IDE(s) for those tools. Eventually we would love to make that package or a new related package accessible to non-technical folks, like teachers. We would love to distribute tools that will allow teachers to build simple activities w/out coding, esp. building extensions to Gcompris (
<a href="http://www.gcompris.net">www.gcompris.net</a>). Some kind of ActivityBuilder program, if there isn't one already in the works. This could be a ways down the line but will be really needed.<br><br>Let me know what you guys think. If anyone has already done all or part of what i have described, please let me know.
