Upgrade Orchestrator for Virtual Machine Component Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtualization systems lack a reliable method for pre-validating upgrades in virtual environments, leading to inefficiencies and downtime, as they do not provide mechanisms for detecting and validating components that require upgrades or ensuring the success of these upgrades, and existing APIs are insufficient for planning updates or reporting upgrade statuses.
Innovation Solution
The implementation of an upgrade service, referred to as an 'upgrade orchestrator,' which performs pre-upgrade component detection and validation on hosts, allowing for parallel processing across multiple hosts, and coordinates upgrades by initiating the upgrade process on a peer host while the VM is powered off, thereby reducing downtime and enhancing upgrade management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional virtualization systems perform upgrades without pre-validation, then the upgrade process is simple and quick, but the reliability of the upgrade is poor and downtime cannot be avoided
Solution Approach 1:
The system performs pre-upgrade validation by detecting component versions and validating upgrade compatibility before the actual upgrade occurs. The upgrade service initializes APIs that detect current component versions (VM, hypervisor, BIOS, firmware) and validate whether the planned upgrade is compatible, preventing failed upgrades and reducing downtime.
2Loss of time
If the VM remains powered on during upgrade, then service continuity is maintained, but upgrade coordination becomes difficult and downtime increases
Solution Approach 1:
The system performs validation and detection operations before powering off the VM for upgrade. By initializing APIs and validating upgrade compatibility while the VM is still running, the system prepares everything in advance, allowing the actual upgrade to proceed quickly once the VM is powered off, thereby minimizing downtime.
3Adaptability or versatility
If existing APIs are used for upgrade management, then the system architecture remains simple, but the ability to detect and validate upgradeable components is insufficient
Solution Approach 1:
The upgrade service initializes separate APIs for different detection and validation functions: one API detects VM version, another detects hypervisor version, another detects BIOS/firmware version, and separate validation APIs check upgrade compatibility. This segmentation allows comprehensive component detection while maintaining clear, organized API structures.

AI summary
The disclosure provides for systems and methods for performing upgrades in virtual environments. Some implementations are directed to using an upgrade service to provide pre-upgrade component detection and validation on host(s). A software package may be submitted to an existing software upgrade procedure of a host. The software package may include an upgrade executable that, when launched, provides a new software service, including initializing one or more new public-facing APIs to provide pre-upgrade host component detection and validation. Some implementations are directed to coordinating the upgrade of a first host using an upgrade service launched on another networked machine or second host. While running an upgrade service, the first host may make a request to the second host to coordinate the upgrade of components of the first host while the first host or a VM of the first host running the upgrade service is shut down.
