What about /var/log/libvirt/qemu/rhel64-64.log? That is the QEMU
command-line and stderr log.
Also can you try without copy-storage-all just to see if migration
completes successfully? The guest will act weird once it migrates since
the disk is zeroed but it will isolate the failure to
--copy-storage-all.
