Supporting USB Devices for the Global Migration

Virtualization has been also used as desktop utility and supports VM migration, which is a function to migrate a VM (Virtual Machine) from a physical host to another. However, it cannot migrate hardware configuration of peripherals. We focus on USB devices as peripherals and provide the USB device connection method by combination of MAT and USB/IP for the global migration. In our system, MAT is implemented into VM and solves mismatch of VM's IP address caused by VM migration. We define VM migration capable of migrating among distinct hosts over different network segments as the global migration. USB device connectivity between host and VM is ensured by USB/IP. Combination of MAT and USB/IP allows a migrated VM to connect a USB device attaching to any hosts after migration. This paper describes the proposed mechanism for the global migration supporting USB devices.
