RE: [Xen-devel] Live Migration Error

[Andrés Lagar Cavilla <andreslc@xxxxxxxxxxxxxx>]

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.
Thanks
Andres
