1. A method comprising:
receiving, by a first computer system and a second computer system, a request to migrate a virtual machine (VM) from a source host system to a destination host system, the request being sent by global mobility manager, the global mobility manager being configured to allocate virtual addresses and routes in a networking routing table;
creating, by the first and second computer systems, a virtual network path between the source and destination host systems, the virtual network path enabling the source and destination host systems to migrate the VM without exposing a physical Internet Protocol (IP) address of the source host system to the destination host system or a physical IP address of the destination host system to the source host system; and
once the VM has been migrated, tearing down, by the first and second computer systems, the virtual network path;
wherein the first computer system and the second computer system reside in different virtual infrastructure management domains and are connected via a wide area network.
