Learn how to implement Hyper-V Live Migration in Windows Server 2022 to move running VMs between hosts with zero downtime, including CPU compatibility and storage requirements.
Production checkpoints give Hyper-V Generation 2 VMs an application-consistent recovery point via guest VSS, but they are not backups and require healthy writers, correct VM settings, and awareness of fallback behavior.
Dynamic Memory lets Hyper-V reclaim idle RAM from guests via the Integration Services balloon driver, enabling safe overcommit. Learn how minimum, maximum and buffer settings work, how to monitor with Get-VMMemory, and the limits to watch.
Hyper-V Replica provides asynchronous VM replication for disaster recovery without SAN or clustering. This post covers prerequisites, configuration choices, a SQL VM example, and the RPO and bandwidth trade-offs to plan for.
Stop wasting host RAM with static allocations. Learn how Hyper-V Dynamic Memory uses ballooning to optimize resource distribution and when to avoid it for high-performance apps.
An architecture note on Hyper-V Dynamic Memory: requirements, a minimal working configuration, how the balloon driver preserves guest memory boundaries, operational checks, failure modes, and when static memory is the better design.
Stop wasting RAM on idle VMs. Learn how to use Hyper-V Dynamic Memory to increase VM density and automatically scale resources based on real-time demand.
Nested virtualization lets a Hyper‑V guest host its own VMs, enabling test labs or CI pipelines on a single server. This post covers enabling the feature on Windows Server 2019+, configuration steps, performance caveats, and a practical example. Test it before production.
A decision guide for Hyper-V live migration on Windows Server 2022: compare shared storage, SMB 3.0, and combined moves, check generation and switch compatibility, then validate the result.
