Abstract
Management of access to input/output devices by a virtual machine (VM) includes executing a hypervisor, and instantiating the VM to execute under supervision of the hypervisor. The VM is to include an I/O device-agnostic (IODA) driver that is configured to interface with the I/O device via a first path according to a set of operational parameters specific to the I/O device, and to interface with the hypervisor via a second path. The IODA driver is to configure the operational parameters to comport with an operational protocol of the I/O device based on device-description information provided to the IODA driver via the second path.
