Technologies are generally described for the secure live migration of virtual machines. The migration may take place in the context of, for example, public clouds. In various embodiments, by using a hidden process incorporated in a virtual machine's kernel and a trusted wireless and/or wired positioning service, a cloud provider and/or cloud user may be alerted about possible virtual machine hijacking/theft. The provider or user may also be provided with an approximate physical location of the platform running the compromised virtual machine for further investigation and enforcement measures.
