Abstract

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.

Dependent claims

A system comprising:

at least one processor;
a memory device including instructions that cause the system to:
launch a computing instance in a computing service environment using a machine image;
receive from a hypervisor virtualized resource information for a virtualized resource utilized by an operating system for the computing instance, wherein the virtualized resource emulates computer hardware utilized by the computing instance;
identify the virtualized resource associated with the virtualized resource information;
load a driver interface layer that accesses a driver operational layer that executes driver functionality enabling the operating system to interact with a virtualized resource;
present the driver interface layer to the operating system;
identify a driver image that is associated with hardware and software used to implement the computing instance, wherein the driver image provides functionality that permits the computing instance to interact with the virtualized resource via the hypervisor;
obtain the driver image for the virtualized resource;
load the driver image into the driver operational layer;
and
register the driver image with the driver interface layer.
