Abstract

A mechanism for inter-cloud live migration of virtualization systems is disclosed. A method of the invention includes receiving notification that live migration of a virtual machine (VM) has completed, wherein the VM is migrated from a source host computing machine on a source cloud to a target host computing machine on a target cloud, receiving requests sent to a previous IP address of the VM associated with the source cloud, the requests routed over a layer-2 (L2) network tunnel established between the source cloud and the target cloud, configuring a new network interface with a new Internet Protocol (IP) address for the VM to receive requests directly via a communication connection of the target cloud, and simultaneously handling the requests at both of the previous IP address received via the L2 network tunnel and the new IP address via the communication connection of the target cloud.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a virtual machine (VM) migrated from a source host computing machine on a source cloud to a target host computing machine on a target cloud, notification that live migration of the VM has completed;
receiving, by the VM, requests sent to a previous IP address of the VM corresponding to the source cloud, the requests routed to the VM via a layer-2 (L2) network tunnel established between the source cloud and the target clo…
