- In this paper, we propose a new remote USB architecture to support live migration of virtual machines in SoD (System on-Demand) service. The SoD (System on-Demand) service is the service that provides virtual personal computers which are optimized virtual machines using distributed u-computing devices around users when the users demand. The virtual USB technology for virtual machines is a kind of I/O virtualization to make users of virtual machines use remote USB devices as local USB devices. In a SoD system, a virtual machine can migrate among some SoD servers even when users use virtual machines due to resource reallocation mechanism of the system. In case of the live migration of the virtual machine, the connection of remote USB to the virtual machine will be broken, which means the break of I/O virtualization. For the seamless I/O virtualization of remote USB in spite of live migration of virtual machines, we propose a new remote USB architecture by adopt the virtual connection manager which sustains the virtual connection among the virtual machine and remote USB devices. With the proposed remote USB architecture, users of the virtual machine use remote USB devices seamlessly without noticing live migration of virtual machines. ©ICROS.
