Abstract

A system includes a number of server computing devices and a management server computing device. Each server computing device has a virtual host computer program running thereon to support one or more virtual machine computer programs. Each virtual machine computer program is able to execute an instance of an operating system on which application computer programs are executable. The management server computing device monitors the server computing devices, and causes the virtual machine computer programs supported by the virtual host computer program of a first server computing device to dynamically migrate to the virtual host computer program of a second server computing device, upon one or more conditions being satisfied. The conditions may include the first server being predicted as failure prone, the first server consuming power less than a threshold, and the first server having resource utilization less than a threshold.

Claims

1. An article of manufacture comprising:

a non-transitory computer-readable medium;

means in the medium for;

predicting a failure at a first server computing device, where prediction of the failure is performed by one of;

a network adapter of the first server computing device, or an agent computer program running on a virtual host computer program running on the first server computing device;

in response to predicting the failure at the first server computing device, communicating the prediction of the failure at the first server computing device to the management server by the one of the network adapter of the first server computing device or the agent computer program running on the virtual host computer program running on the first server computing device, where communication of the prediction of the failure occurs from the one of the network adapter or the agent computer program to the management server without passing through a coordinator server different than the management server;

in response to receiving the communication of the prediction of the failure, correlating the first server computing device with the virtual host computer program running on the first server computing device, by the management server, and sending an identity of the virtual host computer program from the management server to the coordinator server;

in response to receiving the identity of the virtual host computer program from the management server, correlating the virtual host computer program with one or more virtual machine computer programs supported by the virtual host computer program, by the coordinator server, and sending information regarding the virtual machine computer programs from the coordinator server to the management server;

after receiving the information regarding the virtual machine computer programs from the coordinator server, sending an instruction from the management server to the coordinator server to dynamically migrate the virtual machine computer programs from the virtual host computer program of the first server computing device; and

,

in response to receiving the instruction from the management server, dynamically migrating the virtual machine computer programs from the virtual host computer program of the first server computing device to a virtual host computer program of a second server computing device, by the coordinator server.

2. The article of manufacture of claim 1, wherein the means is further for specifying one or more conditions corresponding to the failure predicted at the first server computing device.

3. The article of manufacture of claim 1, wherein the means is further for:

stopping execution of the virtual host computer program of the first server computing device; and

,

turning off the first server computing device.

4. The article of manufacture of claim 1, wherein dynamically migrating the virtual machine computer programs comprises sending a command from a management server computing device to a coordinator server computing device able to control the virtual host computer programs of the first and the second server computing devices.

5. An article of manufacture comprising:

a non-transitory computer-readable medium;

means in the medium for;

detecting resource utilization at a first server computing device less than a threshold, where detection of the resource utilization as less than the threshold is performed by one of;

a network adapter of the first server computing device, or an agent computer program running on a virtual host computer program running on the first server computing device;

in response to the detection, communicating the detection of the resource utilization as less than the threshold to the management server by the one of the network adapter of the first server computing device or the agent computer program running on the virtual host computer program running on the first server computing device, where communication of the detection occurs from the one of the network adapter or the agent computer program to the management server without passing through a coordinator server different than the management server;

in response to receiving the communication of the detection, correlating the first server computing device with the virtual host computer program running on the first server computing device, by the management server, and sending an identity of the virtual host computer program from the management server to the coordinator server;

in response to receiving the identity of the virtual host computer program from the management server, correlating the virtual host computer program with one or more virtual machine computer programs supported by the virtual host computer program, by the coordinator server, and sending information regarding the virtual machine computer programs from the coordinator server to the management server;

after receiving the information regarding the virtual machine computer programs from the coordinator server, sending an instruction from the management server to the coordinator server to dynamically migrate the virtual machine computer programs from the virtual host computer program of the first server computing device; and

,

in response to receiving the instruction from the management server, dynamically migrating the virtual machine computer programs from the virtual host computer program of the first server computing device to a virtual host computer program of a second server computing device, by the coordinator server.

6. The article of manufacture of claim 5, wherein the means is further for specifying one or more conditions corresponding to the resource utilization at the first server computing device less than the threshold.

7. The article of manufacture of claim 5, wherein the means is further for:

stopping execution of the virtual host computer program of the first server computing device; and

,

turning off the first server computing device.
