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.
I appologize for this. I ca paste the text version.
In the destinaiton host's /var/log/libvirt/qemu/vm.log
It is described as:

qemu: warning: error while loading state section id 2
load of migration failed
2011-10-28 11:29:32.401: shutting down
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.
I have created the right image file on the destination host.I have already
reardown the apparmor. I want to know how to shut down the selinux on the
ubuntu server.
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.
The version of libvit I am using is:
Compiled against library : libvir 0.8.8
Using library: libvir 0.8.8
Using API : QEMU 0.8.8
Runing hypervisor: QEMU 0.14.0
