The virtual machine can comprise a guest operating system hosting the introspection daemon. The configuration state data can comprise an execution state of an application running on the guest operating system of the virtual machine. The processor can generate a virtual machine image of the virtual machine in view of the introspection report. The processor can further initiate a migration of the virtual machine to at least one target cloud in view of the virtual machine image. ## Claims ### Claim 1 A method comprising: receiving, by a processor executing a kernel-based service integrated in a kernel of a centralized server that manages a set of virtual machines, from an introspection daemon running on a virtual machine in the set of virtual machines, an introspection report comprising configuration state data of the virtual machine for a migration of the virtual machine to at least one target cloud of a plurality of clouds managed by the centralized server, wherein the virtual machine comprises a guest operating system hosting the introspection daemon, wherein the configuration state data comprises an execution state of an application running on the guest operating system of the virtual machine, and wherein the centralized server manages another set of virtual machines in the at least one target cloud;
