Abstract:

The authors proposed a novel approach of virtual machine live migration in crossdomain virtual networks. A virtual network routing protocol was presented to support crossdomain communication between VMs. A VM migration protocol controlling the migration process was designed to enable dynamic management of virtual infrastructure. We implemented a prototype based on a typical virtualization tool, Xen. VM Live migration method presented in this work enables dynamic virtual infrastructures extending to widearea network.

Key words: virtual network, virtual machine, crossdomain live migration, routing protocol, VM migration protocol
