Virtual Desktop Provisioning via Offline Domain Join
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional virtual desktop customization in VDI environments is time-consuming and inefficient, requiring multiple reboots, leading to boot storms, network traffic issues, and security concerns due to shared domain controller credentials, especially in large-scale deployments.
Innovation Solution
A method for provisioning virtual desktops without rebooting the VM by applying configurations and customizations to a virtual disk while it's powered off, using techniques like offline domain joining and modifying registry hives, allowing the VM to join a domain and power on without additional reboots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional virtual desktop customization methods are used with multiple reboots, then domain membership and system configurations can be established, but deployment time increases significantly to 12-15 hours for 1000 desktops
Solution Approach 1:
The patent applies preliminary action by performing domain membership configuration and system customizations before the virtual desktop is powered on for the first time. The composition service configures the virtual desktop offline, pre-joining it to the domain and applying all necessary customizations, so that when the desktop is powered on, it is already fully configured and ready for use, eliminating the need for multiple reboots during customization.
2Ease of operation
If multiple VM reboots are performed during customization, then configuration changes take effect, but boot storms occur causing network traffic issues and CPU overload
Solution Approach 1:
The patent eliminates boot storms by performing all configuration changes in advance before the virtual desktop is powered on. The composition service applies domain membership, system profiles, and customizations offline, so that when the desktop starts, no additional reboots are needed. This preliminary configuration approach prevents the concentration of reboot events that cause boot storms.
3Adaptability or versatility
If domain controller credentials are shared with all clone VMs for domain joining, then domain membership is established, but security is compromised
Solution Approach 1:
The patent improves security by performing domain joining in advance during the offline configuration phase. The composition service joins each virtual desktop to the domain before it is powered on and assigned to a user, using secure credential management. This preliminary domain joining eliminates the need for virtual desktops to share domain controller credentials during runtime, reducing security risks associated with credential sharing.
Data Source
AI summary
Techniques are disclosed for provisioning a virtual desktop. A VM hosting the desktop may be joined to a domain using offline domain join and customized by modifying contents of a virtual disk of the VM, as per the customization requirements, without powering on the VM. While the VM is powered off, a composer application customizes the VM by applying system and user profile configuration changes and network configuration changes, as well as optionally creating a user data disk and pushing to the VM a script for formatting said disk during the VM's first power-on. In addition, while the VM is powered off, the composer invokes a domain joining tool to join the VM to a domain controller without having to reboot the VM. A snapshot is then taken of the VM, after which the VM is then powered on and the script for formatting the user data disk executes.
