Abstract:
1. A computer implemented method for synchronizing changes in virtual machines (VMs) between two or more systems, the method comprising: obtaining, by a first system, a virtualization snapshot of a source VM; receiving, by the first system, instructions for execution, wherein the execution is performed using the source VM; executing, by the first system, the received instructions resulting in modifications of the source VM, wherein the virtualization snapshot stores modified portions of the source VM separate from the source VM, sending, by the first system, the modified portions of the source VM to a second system comprising a destination VM, wherein the destination VM matches the source VM before the modifications; receiving, by the second system, the modified portions from the first system; and applying, by the second system, the modified portions to the destination VM to obtain a modified destination VM that matches the modified source VM.
