Abstract

Embodiments of the present disclosure call for a method, a system, and a computer program product for managing virtual resources for a virtual machine of interest on a physical server. The method includes monitoring a plurality of physical servers, on a computing system. Each physical server provides an initial level of virtual resources to a plurality of virtual machines. The method also includes receiving a requested level of virtual resources for a virtual machine of interest hosted by a first physical server from the plurality of physical servers. The method also includes determining whether the first physical server is able to host the requested level of virtual resources for the virtual machine of interest. The method also includes determining, in response to the first physical server not being able to host the requested level of resources for the virtual machine of interest, a path.

Claims

1. A system comprising:

a plurality of physical servers operating in a computing environment, a physical server configured to provide virtual resources at an initial level to a plurality of virtual machines;

a cloud controller that manages virtual resources for the plurality of virtual machines, the cloud controller further configured to;

monitor the plurality of physical servers that provide an initial level of virtual resources to the plurality of virtual machines;

receive a requested level of virtual resources for a virtual machine of interest hosted by a first physical server from the plurality of physical servers;

determine whether the first physical server is able to host the requested level of virtual resources for the virtual machine of interest;

determine, in response to the first physical server not being able to host the requested level of resources for the virtual machine of interest, a path to accommodate the virtual machine of interest involving a schedule of actions for a plurality of secondary virtual machines on the plurality of physical servers, the path determined by;

resizing the plurality of secondary virtual machines to create unallocated virtual resources,

measuring unallocated virtual resources in the plurality of physical servers, and

migrating the plurality of virtual machines to the plurality of physical servers with sufficient unallocated virtual resources to accommodate the virtual machine of interest; and

implement the path for the secondary virtual machines on the plurality of physical servers.

2. The system of claim 1, wherein the cloud controller is further configured to:

increase, in response to the first physical server being able to host the requested level of resources for the virtual machine of interest, the virtual resources to the requested level for the virtual machine of interest on the first physical server.

3. The system of claim 1, wherein migrating the plurality of virtual machines includes:

determining whether the virtual machine of interest is able to be migrated to a second physical server from the plurality of servers; and

migrating the virtual machine of interest to the second physical server in response to the virtual machine of interest being able to be migrated to the second physical server.

4. The system of claim 1, wherein resizing the plurality of secondary virtual machines includes:

determining an operating threshold of the plurality of secondary virtual machines; and

resizing the plurality of secondary virtual machines to the operating threshold.

5. The system of claim 1, wherein the cloud controller is further configured to:

increase the virtual resources to the requested level for the virtual machine of interest.

6. The system of claim 1, wherein the cloud controller is configured to determine the path by:

predicting the schedule of actions that define a path; and

determining whether the schedule of actions is within an action threshold; and

implementing the path in response to the schedule of actions being within the action threshold.

7. A computer program product comprising a computer readable storage device having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

monitor a plurality of physical servers, on a computing system, that each provide an initial level of virtual resources to a plurality of virtual machines;

receive a requested level of virtual resources for a virtual machine of interest hosted by a first physical server from the plurality of physical servers;

determine whether the first physical server is able to host the requested level of virtual resources for the virtual machine of interest;

implement, in response to the first physical server not being able to host the requested level of resources for the virtual machine of interest, a path to accommodate the virtual machine of interest involving a schedule of actions for a plurality of secondary virtual machines on the plurality of physical servers, the path implemented by;

resizing the plurality of secondary virtual machines to create unallocated virtual resources;

measuring unallocated virtual resources in the plurality of physical servers; and

migrating at least some of a resized plurality of secondary virtual machines to the plurality of physical servers with sufficient unallocated virtual resources to accommodate each secondary virtual machine so that the first physical server has sufficient unallocated virtual resources to accommodate the virtual machine of interest.

8. The computer program product of claim 7, wherein the computer readable program causes the computing device to:

increase, in response to the first physical server being able to host the requested level of resources for the virtual machine of interest, the virtual resources to the requested level for the virtual machine of interest on the first physical server.

9. The computer program product of claim 7, wherein the computer readable program causes the computing devices to implement the path by:

determining whether the virtual machine of interest is able to be migrated to a second physical server from the plurality of servers; and

migrating the virtual machine of interest to the second physical server in response to the virtual machine of interest being able to be migrated to the second physical server.

10. The computer program product of claim 9, wherein the virtual machine of interest is able to be migrated in response to the second physical server having sufficient unallocated virtual resources for the virtual machine of interest.

11. The computer program product of claim 7, wherein resizing the plurality of secondary virtual machines includes:

determining an operating threshold of the plurality of secondary virtual machines; and

resizing the plurality of secondary virtual machines to the operating threshold.

12. The computer program product of claim 7, wherein the computer readable program causes the computing device to:

increase the virtual resources to the requested level for the virtual machine of interest.

13. The computer program product of claim 7, wherein the computer readable program causes the computing device to implement the path by:

predicting the schedule of actions that define a path; and

determining whether the schedule of actions is within an action threshold; and

implementing the path in response to the schedule of actions being within the action threshold.
