Abstract: Examples include techniques for input/output (I/O) access to physical memory or storage by a virtual machine (VM) or a container. Example techniques include use of a queue pair maintained at a controller for I/O access to the physical memory or storage. The queue pair including a submission queue and a completion queue. An assignment of a process address space identifier (PASID) to the queue pair facilitates I/O access to the physical memory or storage for a given VM or container.
