You mentioned this on IRC, but you haven't actually given anything near a real bug report. :-) xl localhost migrate is tested in osstest, and we just had that bug with the timing for PVHVM guests that we fixed a few weeks ago -- that involved doing 100+ localhost migrates. Without some more specification, and/or someone else reporting the issue, I can only assume it's something local to your configuration. -George
