Control VM Content Abstraction Layer for Offline Virtual Desktop Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual desktop solutions face challenges in providing uniform access to remote virtual desktop content across different devices and network conditions, particularly when the virtual desktop is not running, and in managing data access efficiently for offline usage.
Innovation Solution
The Enhanced Virtual Desktop Management Server employs a Content Abstraction Layer and a Control VM to abstract data access, allowing users to access their data and applications from various devices without needing a running virtual desktop, by mounting or accessing data disks on the fly, and utilizing a Control VM to retrieve data from non-running virtual machines or cloud storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a virtual desktop is not running, then energy consumption is reduced and device resources are saved, but data accessibility becomes difficult
Solution Approach 1:
A control virtual machine is introduced as an intermediary component that runs in the background and provides data access services to clients even when the main virtual desktop is not running. The control VM mounts virtual disks and exposes their contents through a content abstraction layer, enabling data accessibility without requiring the full desktop environment to be active.
Solution Approach 2:
The virtual desktop system is segmented into separate functional components: the main virtual desktop (which can be off) and the control virtual machine (which remains active for data access). This segmentation allows data accessibility to be maintained independently of the desktop's operational state, resolving the contradiction between energy savings and data accessibility.
2Ease of operation
If a control virtual machine is introduced to access data from non-running virtual machines, then data accessibility is improved, but system complexity increases
Solution Approach 1:
The control virtual machine is designed as a universal service provider that can access any virtual disk from any virtual machine in the infrastructure. Rather than creating separate access mechanisms for each VM type, the control VM provides a unified interface through the content abstraction layer, reducing overall system complexity despite adding a new component.
Solution Approach 2:
Instead of requiring clients to directly connect to complex virtual machine storage systems, a simplified copy mechanism is introduced where the control VM mounts virtual disks and serves their contents to clients through a standardized interface. This copying approach abstracts away the complexity of the underlying virtualization infrastructure.
3Quantity of substance
If virtual disks are mounted on-demand, then device resource usage is reduced, but access time increases
Solution Approach 1:
The control virtual machine proactively mounts virtual disks before clients need to access them, based on predicted or pre-known access patterns. This preliminary action ensures that data is ready for immediate access when clients connect, reducing perceived access time while maintaining resource efficiency by only mounting disks that are actually needed.

AI summary
Methods, systems, and techniques for facilitating access to content stored remotely, for example, as part of a virtual machine infrastructure or elsewhere in a networked environment, using a uniform mechanism are provided. Example embodiments provide an Enhanced Virtual Desktop Management Server/System with a Content Abstraction Layer which enables users to access their data stored as part of a virtual machine environment, or replicated otherwise on a network, using a generic API. The API can be incorporated into a web browser or other third party interface to provide access to the users' data without needing to remote a bitmap representation of a virtual desktop display. Accordingly, users can access their data, applications, and settings regardless of the type of access device and regardless of whether the corresponding virtual desktop is running in the data center, provisioned in the datacenter but running on a client device, or not running at all.
