Your jpg takes up a lot of bandwidth; it would be more efficient if you 
copy and paste the text from your console, rather than a screenshot of 
the console.

As to the actual error, I'm not sure if I can offer advice until I try 
to reproduce it, but I do know that --copy-storage-all hasn't received 
as much testing.  Make sure that an empty file exists on the destination 
prior to the migration attempt, in case the error is stemming from qemu 
on the destination unable to open the file with SELinux permissions in 
force.

Also, what version of libvirt are you using?  Newer libvirt tries harder 
to avoid the lame error messages from qemu being unable to start a 
migration without giving any reasons why.
