Virtual Machine Mobility Using OpenFlow

A computer program product for migrating virtual machines (VMs), the computer program product comprising:

• a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• creating a temporary storage area, the creating by a controller in a network, the network in a first state;
• storing configuration data for a VM, the storing in the temporary storage area;
• provisioning the network from the first state to a second state, the provisioning by the controller and based on network locations of a source server and a target server;
• transmitting a message to the target server, the message including:
• a request to migrate the VM from the source server to the target server;
• and
• an address of the temporary storage area;
• determining that the migration has completed;
• and
• removing the temporary storage area based on the determining.

A system for migrating virtual machines (VMs) in a network, the system comprising:

• a controller configured to connect to the network, the controller comprising:

• and
• a processor for executing the computer readable instructions, the instructions including:
• creating a temporary storage area, wherein the network is in a first state;
• storing configuration data for a VM, the storing in the temporary storage area;
• provisioning the network from the first state to a second state, the provisioning based on network locations of a source server and a target server;
• transmitting a message to the target server, the message including:
• a request to migrate the VM from the source server to the target server;
• and
• an address of the temporary storage area;
