RE: [Xen-devel] Live Migration Error

It's unlikely that I caught that fix on my last code pull, more than 3 hours ago. However, live migration didn't work and after tweaking the timeout it did work, so the timeout solution deserves some credence.
I'll make sure I get that fix, recompile, re-run and report.

I'd be really surprised if increasing the timeout actually made a difference. Are you sure you're not just using the shadow mode fix that was checked in a couple of hours ago?
