Hyper-V Dynamic Memory can double VM density on a host, but only if you size Startup, Minimum, and Maximum RAM against real peak behavior. A worked 64 GB host example shows how.
An architectural deep dive into Windows 11's WSL2, explaining the utility VM, the 9P protocol for cross-OS file access, and how to manage memory boundaries via .wslconfig.
The goal is to configure Hyper‑V Replica so that a retry of a failed replication pass does not cause the same write to be applied twice on the replica VM. When a replication pass encounters a transient network error, Hyper‑V may retry the transfer of the changed blocks. If the retry resends blocks that were already partially committed, the replica could see
I've created a windows Hyper-V VM on a Windows 10 (X64) 2004 Pro host. I'm using the Hyper-V manager console, and the VM is working fine and has internet connectivity when using the default switch. I'm trying to configure it so that the VM receives IP address and gateway from the network DHCP, not from the Hyper-V. I've used the Virtual Switch Manager to cre
Hyper-V Discrete Device Assignment (DDA) allows a virtual machine to directly control a physical PCIe device, such as an NVMe controller or GPU, rather than using emulated virtual hardware. The feature was introduced with Windows Server 2016 and Windows 10, and its supported device classes and management options can differ across later releases such as Windo
Live Migration of a small application VM with RDMA enabled I am planning to move a small application running in a Hyper-V VM between two hosts using Live Migration, with the goal of no perceptible downtime for users. The research available to me confirms that Live Migration is a documented zero-downtime feature, and that RDMA (SMB Direct) can be used to spee
Goal Determine the expected state of a virtual machine's network adapters after a Live Migration is cancelled—whether by explicit Stop-VM or an implicit timeout—so that automation can reliably restore connectivity without manual inspection. Constraints and uncertainty Microsoft documentation does not specify whether a cancelled migration rolls back adapter c
Goal I want to run a few VMs on a Windows machine with client Hyper-V and give them outbound internet access, without any of them becoming reachable from other devices on my LAN or, worse, from the public internet. I am trying to decide between attaching the VMs to an external virtual switch bound to my physical NIC versus leaving them on the Default Switch.
Goal Establish a development environment that can be reliably reproduced across CI pipeline runs, minimizing drift caused by host‑level changes. Constraints Hyper‑V hosts may receive OS patches or be upgraded to newer Windows Server releases. Checkpoints capture the entire VM state, but the Hyper‑V API does not guarantee deterministic consistency after a hos
