Securing live migration of a virtual machine from a secure virtualized computing environment, over an unsecured network, to a different virtualized computing environment

A virtualized computing data processing system comprising:

• a secure virtualized computing environment comprising a host server including a hypervisor managing a plurality of virtual machines (VMs) within the secure virtualized computing environment;
• a different virtualized computing environment coupled to the secure virtualized environment over an unsecured computer communications network, the different virtualized computing environment comprising a host server including a hypervisor managing a plurality of VMs within the different virtualized computing environment;
• and
• live migration logic executing in a computer and communicating with each of the secure virtualized computing environment and the different virtualized computing environment, the logic comprising program code enabled to select one of the VMs in the secure virtualized computing environment for live migration to the different virtualized computing environment and to block data communications between the selected VM and other VMs in the secure virtualized computing environment, to live migrate the selected VM to the different virtualized computing environment and to restart the selected VM in the different virtualized computing environment, to establish a secure communicative link between the different virtualized computing environment and the secure virtualized computing environment, and to enable data communications between the restarted VM and the other VMs in the secure virtualized computing environment over the secure communicative link.
