第二计算装置
第二计算设备
after execution of a virtual machine by a first computing device has stopped, wherein the virtual machine is communicatively coupled to a virtual private network (VPN) via a first attachment circuit using a first set of network parameters while executed by the first computing device, receiving, by a second computing device, checkpoint data for the virtual machine, wherein the checkpoint data represents state information for the virtual machine
In one example, a system includes a first computing device configured to execute a virtual machine, wherein the virtual machine is communicatively coupled to a virtual private network (VPN) via a first attachment circuit using a first set of network parameters, stop execution of the virtual machine, and create checkpoint data for the virtual machine, and a second computing device configured to execute the virtual machine, using at least some of the checkpoint data, and to cause the virtual machine to become communicatively coupled to the VPN via a second attachment circuit using a second set of network parameters different from the first set of network parameters.
In another example, which may be implemented in addition to the example above, the system further includes a first provider edge (PE) routing device communicatively coupled to the first computing device via the first attachment circuit, and a second PE routing device communicatively coupled to the second computing device via the second attachment circuit.
In another example, which may be implemented in addition to the example above, determining that the virtual machine has migrated comprises receiving information from a network management system (NMS) indicating that the virtual machine has migrated to the second computing device.
executing, by the second computing device, the virtual machine using at least some of the checkpoint data to move execution of the virtual machine from the first computing device to the second computing device; and
Moreover, the system may include a network management system configured to cause the virtual machine to migrate from the first computing device to the second computing device and to send a message to the second PE routing device indicating that the virtual machine has migrated to the second computing device.
in response to determining that the virtual machine has migrated to the second computing device, sending a message from the routing device to the second computing device including a second set of network parameters for causing the virtual machine to become communicatively coupled to the VPN via a second attachment circuit, wherein the second set of network parameters are different from the first set of network parameters, and wherein the second attachment circuit couples the virtual machine to the routing device.
In another example, which may be implemented in addition to any of the examples above, the instructions that cause the processor to determine the second set of network parameters comprise instructions that cause the processor to receive a message from a provider edge (PE) routing device to which the second computing device is communicatively coupled, wherein the message includes data specifying the second set of network parameters.
In another example, a method includes determining, by a provider edge (PE) routing device, that a virtual machine has migrated from a first computing device to a second computing device, wherein the virtual machine is communicatively coupled to a virtual private network (VPN) via a first attachment circuit using a first set of network parameters while executed by the first computing device, and wherein the PE routing device is communicatively coupled to the second computing device, and in response to determining that the virtual machine has migrated to the second computing device, sending an Internet control message protocol (ICMP) router advertisement message to the second computing device including a second set of network parameters for causing the virtual machine to become communicatively coupled to the VPN via a second attachment circuit, wherein the second set of network parameters are different from the first set of network parameters, and wherein the second attachment circuit couples the virtual machine to the PE routing device.
In another example, which may be implemented in addition to any of the examples above, the system further includes a network management system (NMS) configured to cause the virtual machine to migrate from the first computing device to the second computing device and to send a message to the second PE routing device indicating that the virtual machine has migrated to the second computing device, wherein the second PE routing device is configured to send a message to the second computing device, the message including the second set of network parameters for causing the virtual machine to become communicatively coupled to the VPN via the second attachment circuit.
