The modification to do a checkpoint using the live migration mechanism of pre-copying is a trivial one and just something we're benchmarking against with our CoW solution. Here's a patch that changes 'xm save -c' to do the checkpoint using the live migration mechanism instead of the default way. Word of warning: it's a hack and I haven't made the changes necessary so that the checkpoint file won't contain the pages copied during the copy rounds so the checkpoint file will be much larger than necessary. I'm not sure why a checkpoint with pre-copying mechanism hasn't been enabled in Xen yet as the necessary code is all there.
