Computing instance migration

A computer implemented method, comprising:

• obtaining specifications for a source computing instance located on a source physical host, using one or more processors of a computing system, in preparation to migrate the source computing instance to a destination physical host;
• identifying a computing resource of the source physical host used by the source computing instance that is capable of being emulated on a candidate physical host, using the one or more processors of the computing system;
• identifying a destination physical host for hosting a destination computing instance modeled on the source computing instance, using the one or more processors of the computing system, the destination physical host having a core feature set of hardware resources that are capable of supporting the destination computing instance modeled on the source computing instance and the destination physical host is capable of emulating the computing resource of the source physical host;
• and
• comparing a source model of the source computing instance as hosted on the source physical host with a destination model of the source computing instance as hosted on the destination physical host to identify a conflict between the source model and the destination model using the one or more processors of the computing system, the conflict indicating an incompatibility between the source model and the destination model that is resolvable by emulating the computing resource of the source physical host on the candidate physical host.

A system comprising:

• a processor;
• a memory device including instructions that, when executed by the processor, cause the system to:
• analyze a source computing instance located on a source physical host to identify source computing instance specifications in preparation to migrate the source computing instance to a destination physical host;
• analyze physical hosts to identify a candidate physical host as a possible host for hosting a destination computing instance modeled on the source computing instance, the candidate physical host having a core set of hardware resources determined to support the destination computing instance;
• create a source model of the source computing instance as hosted on the source physical host using the source computing instance specifications and source physical host specifications;
• create a destination model of the source computing instance as hosted on a selected candidate physical host using the source computing instance specifications and the core set of hardware resources of the candidate physical host;
• and
• compare the source model with the destination model to identify conflicts between the source model and the destination model indicating incompatibilities that are resolvable by emulating computing resources of the source physical host on the candidate physical host;
• and
• reconcile the conflicts between the source model and the destination model resulting in migrating the source computing instance to the destination physical host.
