Abstract
Virtualization technologies are widely used, and include Live Migration which moves running virtual machines between different physical hypervisors for dynamic load-balancing. In addition, Global Live Migration with IP mobility is also proposed. It enables migration among distributed sites and provides continuation even if the network of the virtual machines was changed. However, it supports only IP unicast communication, not IP multicast communication. In this paper, we propose a mobility support mechanism for IP multicast on virtual machines, and evaluate its basic performance using prototype system. As a result, the proposed method can provide migration function continuously receiving multicast stream stopped same as ordinary Live Migration.
