9. The IHS of claim 1 , wherein the VM is executed on behalf of a client IHS, and wherein the program instructions, upon execution, further cause the IHS to: (a) determine that the VM file is designed to be moved during runtime, wherein the context information comprises a user's presence before the client IHS, and wherein the modification of the usage classification comprises an upgrade in the usage classification; or (b) determine that the VM file is designed to be moved during runtime, wherein the context information comprises a user's absence from the client IHS, and wherein the modification of the usage classification comprises a downgrade in the usage classification.
10. The IHS of claim 1 , wherein the VM is executed on behalf of a client IHS, and wherein the program instructions, upon execution, further cause the IHS to: (a) determine that the VM file is designed to be moved offline, wherein the context information comprises a user's absence before the client IHS, and wherein the modification of the usage classification comprises an upgrade in the usage classification; or (b) determine that the VM file is designed to be moved offline, wherein the context information comprises a user's presence before the client IHS, and wherein the modification of the usage classification comprises a downgrade in the usage classification.
