Abstract

Systems and methods for enabling a user space process of a guest operating system to initiate hardware operations in a security-enhanced manner. An example method may comprise: configuring a storage unit to store resource requests of one or more user space processes, wherein the storage unit is accessible to a hypervisor and to a user space process managed by a guest operating system; determining, by a processing device, that the user space process managed by the guest operating system is authorized to store a resource request at the storage unit; and receiving, by the hypervisor, a signal from the user space process, wherein the signal is associated with the storage unit and initiates execution of the resource request.
