VIRTUAL FIREWALL MOBILITY

摘要

A cloud management device determines that a virtual machine should be migrated from a first host to a second host, the virtual machine being associated with a virtual service, such as a virtual firewall, in the first host. The cloud management device verifies if fonctionality corresponding to the virtual service is available in the second host if the required ninctionality is not available, a new virtual service is instaicted to be instantiated in the second host State synchronization can be performed between the virtual services in the first and second hosts. The cloud management device instructs the virtual machine to be instantiated in the second host.
