From 8414ff3bd8bfafbcb632c670f4d81c8e4f15e703 Mon Sep 17 00:00:00 2001 From: Juan Quintela Date: Wed, 23 Feb 2011 19:56:52 +0100 Subject: migration: propagate error correctly unix and tcp outgoing migration have error values, but didn't returned it. Make them return the error. Notice that EINPROGRESS & EWOULDBLOCK are not considered errors as call will be retry later.
