Abstract
An approach is provided to apply a virtual machine (VM) image to a computer system. In the approach, implemented by an information handling system, a detection is made that a current VM image executing on the computer system is experiencing a problem. In response, prior VM images are analyzed, with each of the prior VM images being an image that was previously executed on the computer system. Based on the analysis, one of the prior VM images is selected and the selected image is used to replace the current VM image on the computer system.

An information handling system comprising:
- a plurality of processors;
- a memory coupled to at least one of the processors;
- a nonvolatile storage area;
- and
- a set of instructions stored in the memory and executed by at least one of the processors to apply a virtual machine (VM) image to a computer system, wherein the set of instructions perform actions of:
- detecting that a current VM image executing on the computer system is experiencing a problem;
- analyzing one or more prior VM images, wherein each of the prior VM images previously executed on the computer system;
- selecting one of the prior VM images based on the analysis;
- and
- replacing the current VM image with the selected prior VM image.
A computer program product stored in a computer readable medium, comprising computer instructions that, when executed by an information handling system, applies a virtual machine (VM) image to a computer system by causing the information handling system to perform actions comprising:
- detecting that a current VM image executing on the computer system is experiencing a problem;
- analyzing one or more prior VM images, wherein each of the prior VM images previously executed on the computer system;
- selecting one of the prior VM images based on the analysis;
- and
- replacing the current VM image with the selected prior VM image.
