Methods and systems for seamless virtual machine changing for software applications

A method comprising:

• receiving, by a virtualization server, a request to provide a virtual machine (VM) to a client device;
• instantiating a first VM on the virtualization server;
• intercepting a request to the first VM to execute an application;
• determining, based on a comparison of a resource consumption profile of the application with a resource configuration profile of the first VM, whether the application is to be executed on the first VM or not;
• upon determining that the application will not be executed on the first VM:
• determining, based on a comparison of the resource consumption profile of the application with resource configuration profiles of a plurality of second VMs, whether the application is to be executed on a second VM of the plurality of second VMs or not;
• upon determining that the application will not be executed on any of the plurality of second VMs:
• establishing a new resource configuration profile to support execution of the requested application;
• instantiating a new second clone VM where the new second clone VM is a linked clone of the base VM with the new resource configuration profile;
• instantiating the application on the new second clone VM;
• and
• causing the application instantiated on the new second clone VM to be accessible.
