From ef4b722d19cab845eaa0d1f912018b09a9d8288b Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Thu, 11 Jun 2015 18:17:28 +0100 Subject: Fail more cleanly in mismatched RAM cases If the number of RAMBlocks was different on the source from the destination, QEMU would hang waiting for a disconnect on the source and wouldn't release from that hang until the destination was manually killed. Mark the stream as being in error, this causes the destination to die and the source to carry on. (It still gets a whole bunch of warnings on the destination, and I've not managed to complete another migration after the 1st one, still progress).
