[one-users] onevm migrate error in opennebula-3.8.3;

[cmcc.dylan]

Hi!
    I meet an error when i execute the command - onevm migrate, and the error log as follows. I know migration action is consisted of three sub-actions: virsh save --> scp disk.0 and checkpoint --> virsh restore. Howerver, I cann't see logs of "scp disk.0 and checkpoint". what is that all about?
   Wether or not  i ignore something or i don't understand the source code well.
