Virtual machine device access
First Claim
1. A computer-implemented method comprising:
- running, on an operating system of a device, a virtual machine, a scheduler and a service provider;
identifying, by the scheduler, a first asynchronous request from the virtual machine, where the first asynchronous request is for accessing one or more of the device'"'"'s information or services;
retrieving, by the scheduler, the first asynchronous request from the virtual machine;
scheduling, by the scheduler, the first asynchronous request to be provided as a second request to the service provider on the device, where the service provider is operable to handle the second request;
providing, by the scheduler, the second request to the service provider;
invoking, by the service provider, an operating system call to the operating system of the device based on the second request;
receiving, by the service provider, an operating system response;
receiving, by the scheduler, a first response from the service provider;
providing, by the scheduler and to the virtual machine a second response;
selecting, by the virtual machine, first code in the virtual machine from a plurality of code to receive the second response and providing the second response to the selected code.

Abstract
The present disclosure includes, among other things, systems, methods and program products for virtual machine device access. A first asynchronous request from a virtual machine executing on a device is identified, where the first asynchronous request is for accessing one or more of the device'"'"'s information or services. The first asynchronous request is retrieved from the virtual machine. The first asynchronous request is scheduled to be provided as a second request to a service provider on the device, where the service provider is operable to handle the second request. The second request is provided to the service provider and a first response is received from the service provider to be provided to the virtual machine as a second response. First code is selected in the virtual machine from a plurality of code to receive the second response and providing the second response to the selected code.
