1. A method comprising:

  • launching, by a processor, a first virtual machine running a first introspection daemon and a second virtual machine running a second introspection daemon;

    accessing, by the processor executing a kernel-based service integrated in a kernel of a cloud operating system associated with a set of host clouds, the first introspection daemon running on the first virtual machine in the set of host clouds;

    receiving, by the kernel-based service from the first introspection daemon, an introspection report comprising configuration state data of the first virtual machine, wherein the first virtual machine comprises a guest operating system hosting the introspection daemon, and wherein the configuration state data comprises an execution state of a thread associated with an application running on the guest operating system of the first virtual machine;

    generating, by the kernel-based service, a virtual machine image of the first virtual machine in view of the introspection report; and

    initiating a migration of the first virtual machine to at least one target cloud in view of the virtual machine image.
