Automatic self-adjusting software image recommendation

A non-transitory computer readable medium comprising instructions that are executable in a computer system, wherein the instructions when executed cause the computer system to carry out a method of updating a desired state of a virtualization software to be installed in a cluster of hosts, wherein the virtualization software includes at least a base image and an add-on image, said method comprising:

• in response to a notification of a change associated with the cluster, determining versions of the base image that are compatible with the cluster;
• for each compatible version of the base image, determining versions of the add-on image that are compatible with the compatible version of the base image and the cluster;
• presenting as a recommended image a complete image of the virtualization software, the complete image containing a first version of the base image that is compatible with the cluster and a first version of the add-on image that is compatible with the first version of the base image and the cluster;
• and
• upon acceptance of the recommended image, updating a software specification to include the recommended image, the software specification expressing the desired state of the virtualization software.

A computer system comprising:

• a plurality of hosts;
• and
• a management server executing instructions to manage the hosts as a cluster and to update a desired state of a virtualization software to be installed in the hosts, wherein the instructions cause the management server to carry out a method comprising:
• in response to a notification of a change associated with the cluster, determining versions of the base image that are compatible with the cluster;
• for each compatible version of the base image, determining versions of the add-on image that are compatible with the compatible version of the base image and the cluster;
• presenting as a recommended image a complete image of the virtualization software, the complete image containing a first version of the base image that is compatible with the cluster and a first version of the add-on image that is compatible with the first version of the base image and the cluster;
• and
• upon acceptance of the recommended image, updating a software specification to include the recommended image, the software specification expressing the desired state of the virtualization software.
