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.
I have scheduled live migration with shared storage (nfs),
looks like
that is only not working properly.
I have turned on the verbose it goes to 99% and sometimes even reaches
100% again comes back 96%
very inconsistent. I will update the result by tomorrow.
