<br><br> Hum, I don't really see how swarming could work for migrating VM images,<br>swarming works on the princimple that a lot of (network) clients are interested<br>in large *immutable* sequence of data, so that you can spead the large
<br>sequence in a number of tiny sets and then use the aggregated bandwidth of<br>the network crossbar to diffuse the whole sequence to the whole set of<br>clients.<br> The problem is that VM state in a migration is of interest to only a single
<br>target machine, and that data sequence mutes extremely fast (see the page<br>refresh algorithm of Xen live migration, it still needs a number of cycles<br>and serious bandwidth to compensate live page changes).<br><br>
So my analysis is that swarming won't help for that specific bandwidth<br>need, but I might be wrong or have misunderstood your question.<br><br>Daniel<br><font color="#888888"><br>--<br>Red Hat Virtualization group
