  • Migration of virtual machines
    Patent number: 8875133
    Abstract: To migrate two or more virtual machines in a source hypervisor to a target hypervisor, a list of active and connected virtual machines in the source hypervisor is acquired. Connections between the source virtual machines are rerouted to a buffer so that data flowing between the source virtual machines is captured. The source virtual machines are migrated to a target hypervisor and are connected in the same manner as in the source hypervisor. The buffered data is migrated to the respective migrated virtual machines, and the target virtual machines are activated. The virtual machines can be migrated in order of data flow dependency such that the least dependent virtual machine is migrated first.
    Type: Grant
