Hyper-V Replica Planned Failover: Zero Data Loss Handover With Auto-Reverse
You set up Hyper-V Replica in Part 1 and proved it works via a quarterly drill in Part 2. Now the moment comes: you actually need to move the workload…

Hyper-V Replica Test Failover: A Safe DR Drill With No Production Impact
You stood up Hyper-V Replica in Part 1. Bytes are flowing from the primary host to the replica host every five minutes. The replica VM exists on HVHost02 in a…
Hyper-V Replica in a Domain: Kerberos Setup, Walked End-to-End
Hyper-V Replica is the built-in DR layer in every Hyper-V install. Configure it once and Hyper-V asynchronously copies a VM’s disks to a second standalone host every few minutes; if…
Hyper-V Replica in a Workgroup: Self-Signed Cert Setup End-to-End
Hyper-V Replica is the built-in disaster-recovery layer that ships with every Hyper-V install. It asynchronously copies a VM’s disks (and optionally point-in-time snapshots) to a second standalone Hyper-V host so…
Hyper-V Shared Nothing Live Migration: Move a Running VM Between Hosts Without a SAN
Two standalone Hyper-V hosts. No SAN, no Cluster Shared Volume, no shared anything — each host has its own local storage. A VM on the source host needs to end…
Hyper-V Storage Migration: Move a Live VM Between Disks With Zero Downtime
Disk fills up. Storage gets retired. A workload outgrows its tier. Whatever the trigger, sooner or later you need to move a Hyper-V VM’s files off one disk and onto…
Hyper-V Lab Networking: A NAT vSwitch With One Outbound IP
You’ve got a Hyper-V lab on your laptop or a spare server. You want the guest VMs to reach the internet for Windows updates, package installs, license activation, and the…
Hyper-V Snapshots Part 3: Clone a VM From a Snapshot via Export and Import
Snapshots in Hyper-V are most often used as rollback points — create one before a risky change, revert if the change misbehaves. There’s a second use that’s less obvious but…
Hyper-V Snapshots Part 2: Merging the AVHDX Chain Back Into the Parent VHDX
Part 1 covered creating, applying, and managing snapshots. This post is the consolidation half — what happens when you delete a snapshot and the differencing-disk overlay has to be merged…
Hyper-V Snapshots Part 1: Create, Revert, and Manage VM Save-States
The Hyper-V checkpoint is a save-state of a running VM — configuration, optionally memory, and a differencing-disk overlay that captures every block the VM writes after the snapshot is taken.…
Enable a Virtual TPM on a Hyper-V VM: GUI, PowerShell, and the Prerequisites
The Trusted Platform Module is the small chip on every modern motherboard that handles cryptographic operations the OS doesn’t want to do in plain memory — key generation, key storage,…
Flip a Hyper-V VHDX Between Pre-Allocated and On-Demand: GUI and PowerShell
VHDX disks come in two allocation modes. Pre-allocated reserves the full configured size on the host filesystem at creation time; on-demand allocates space as the guest writes. Each has a…
