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 one or more resource requests, the storage unit being accessible to a user space process managed by a guest operating system and to a hypervisor; 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 transmitting to the hypervisor a signal associated with the storage unit comprising the resource request, the signal being initiated by a hypercall executed by the user space process.
