US Patent 10095537 Driver version identification and update system

A technology is described for a load time updatable driver. An example method may include presenting a driver interface to a computing instance launched in a computing service environment that enables the computing instance to interact with a virtualized resource, where the driver interface is an interface to driver functionality that enables the computing instance to interact with the virtualized resource via a hypervisor. Context information for the computing instance may be obtained and the context information may be used to identify a driver image for the virtualized resource that enables the computing instance to interact with the virtualized resource. The driver image for the virtualized resource may be obtained and the driver image may be loaded into computer memory and registered with the driver interface.
