[virt-tools-list] Unable to migrate guest: operation failed: migration to 'tcp:ubuntu-Clound.wmct.edu:49157' failed: migration failed

[Luengffy XUE]

Hi all,
Migration fail .  I got the  log in the destination hosts.
The belief information is in the error.jpg.
There is no error but the vm shutdown.

The error1.jpg is the virt-manager show the error.

PS: the Port in the iptables is open for the TCP live migration. I think
that the iptables is not the problem.

Waiting for solutions
Thanks in advance.
