[one-users] The virtual machine failure migration！

[David]

Hi， All
     I used OpenNebula3.2.1 version.
     When I execute VM migrate operation，Occasionally the VM appears a  migration failure,
     following log：

execute command : chmod +x *
but ，receive the following error message：

This is what causes problems ?

Thanks! Hope after
