Virtual machine mobility using OpenFlow
First Claim
1. A system for migrating virtual machines (VMs) in a network, the system comprising:
- a network controller configured to connect to the network, the network controller comprising;
a memory having computer readable computer instructions; and
a hardware processor for executing the computer readable instructions, the instructions including;
creating a temporary storage area in the memory of the network controller, wherein the network is in a first state;
storing configuration data for a VM, the storing in the temporary storage area, the temporary storage area dedicated to the VM and not shared with other users, the temporary storage area sized based on an amount of space required to store the configuration data;
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;
determining that the migration has completed; and
removing the temporary storage area based on the determining.

Abstract
A method for migrating virtual machines (VMs) that includes creating a temporary storage area. The temporary storage area is created by a controller in a network that is in a first state. The configuration data for a VM is stored in the temporary storage area. The network is provisioned from the first state to a second state. The provisioning is by the controller and based on network locations of a source server and a target server. A message is transmitted to the target server. The message includes a request to migrate the VM from the source server to the target server, and an address of the temporary storage area. It is determined that the migration has completed and the temporary storage area is removed based on the determining that the migrant has completed.
