Migration attack 

is an attack on the network during VM migration from one place to another. This attack is an exploit on the mobility of virtualization [Lococo09]. Since VM images are easily moved between physical machines through the network, enterprises constantly move VMs to various places based on their usage. For example, VMs from a canceled customer may be moved to a backup data center, and VMs that need maintenance may be moved to a testing data center for changes. Thus, when VMs are on the network between secured perimeters, attackers can exploit the network vulnerability to gain unauthorized access to VMs. Similarly, the attackers can plant malicious code in the VM images to plant attacks on data centers that VMs travel between.
