Managing virtual clustering environments according to requirements

A computer hardware system configured to manage a cluster of a plurality of devices that are used to host a virtual machine, comprising:

• a hardware processor configured to initiate the following executable operations:
• identifying an operating parameter of a device within the cluster that is associated with a requirement for the virtual machine;
• performing a comparison of the requirement for the virtual machine within a current value of the operating parameter while the virtual machine is being hosted by the device;
• displaying a view of the virtual machine operating within the device;
• providing, within the view, a visualization of a result of the comparison;
• generating a capability score for each of the plurality of devices within the cluster;
• generating a device score for each of the plurality of devices within the cluster;
• and
• providing a recommendation of an alternative device to host the virtual machine based upon the capability score and the comparison, wherein
• the visualization indicates the capability score and whether the requirement for the virtual machine is being met by the device hosting the VM,
• the capability score includes:
• a capability value that indicates an amount of capability that is being provided by a capability device, and
• a trend value that represents a direction in which the capability value is changing, and
• the recommendation is based upon a comparison of a trend value of the device that is currently hosting the virtual machine and a trend value of the alternative device.

A computer program product, comprising:

• a computer-readable storage medium having program code stored thereon for managing a cluster of a plurality of devices that are used to host a virtual machine,
• the program code, which when executed by a computer hardware system, causes the computer hardware system to perform:
• identifying an operating parameter of a device within the cluster that is associated with a requirement for the virtual machine;
• performing a comparison of the requirement for the virtual machine within a current value of the operating parameter while the virtual machine is being hosted by the device;
• displaying a view of the virtual machine operating within the device;
• providing, within the view, a visualization of a result of the comparison;
• generating a capability score for each of the plurality of devices within the cluster;
• generating a device score for each of the plurality of devices within the cluster;
• and
• providing a recommendation of an alternative device to host the virtual machine based upon the capability score and the comparison, wherein
• the visualization indicates the capability score and whether the requirement for the virtual machine is being met by the device hosting the VM,
• the capability score includes:
• a capability value that indicates an amount of capability that is being provided by a capability device, and
• a trend value that represents a direction in which the capability value is changing, and
• the recommendation is based upon a comparison of a trend value of the device that is currently hosting the virtual machine and a trend value of the alternative device.
