Running Windows 11 on Linux with KVM/QEMU

on
This guide walks through the full process of running Windows 11 on Linux using KVM/QEMU and Virt-Manager,  the most robust and future-proof setup available today. While tools like VirtualBox still exist, KVM/QEMU has quietly become the gold standard on Linux. It offers: Near-native CPU performance Excellent disk and network throughput Proper UEFI, Secure Boot, and TPM support Long-term compatibility with Windows 11 updates Before starting, make sure you have: A Linux system with virtualization enabled in BIOS Intel: VT-x / VT-d AMD: SVM / IOMMU At least 8 GB RAM (16 GB recommended) Around 80 GB of free disk space A Windows 11 ISO The VirtIO drivers ISO Step 1: Check Virtualization Support Open a terminal and run: egrep -c '(vmx|svm)' /proc/cpuinfo If the result is 1 or higher , virtualization is enabled. If it returns 0 , you’ll need to enable it in your BIOS before continuing. Step 2: Install KVM, QEMU, and Virt-Manager On Ubuntu / Debian-based systems: sudo apt update sudo...

NVTOP

on



NVTOP is a powerful, real-time GPU monitoring tool for Linux that provides a dynamic, interactive terminal user interface (TUI) to monitor NVIDIA GPUs and other vendors’ accelerators. It functions similarly to the Linux process monitor htop but is focused on graphics cards, giving users live stats such as GPU utilization, memory usage, temperature, power draw, and active processes in a visually rich ASCII format within the terminal.

Unlike the static output of tools like nvidia-smi, NVTOP offers a constantly updating and interactive display, allowing users to sort, filter, and zoom without leaving the terminal. It supports multi-GPU setups by displaying all GPUs side-by-side, making it especially useful for data scientists, AI researchers, gamers, and administrators managing high-performance or multi-user GPU environments.

NVTOP is built in C and uses the ncurses library for its terminal-based UI. It queries the NVIDIA Management Library (NVML) to collect GPU statistics and presents the data with minimal performance overhead, suitable for use during remote sessions via SSH or in terminal multiplexers like tmux or screen.

The main benefits and use cases of NVTOP include:

  • Debugging performance bottlenecks by instantly revealing GPU utilization and memory consumption.

  • Managing multi-user GPU resources in shared environments.

  • Optimizing cloud GPU fleet costs by identifying idle GPUs.

  • Monitoring GPU inside Docker or Kubernetes containers (if device access is enabled).

  • Real-time visibility for home users or server admins who want detailed GPU status without leaving the terminal.

  • Integration with scripts or automated alerts based on GPU state changes.

Installation on Ubuntu and many Linux systems is straightforward with package managers or building from source, requiring dependencies such as cmake and ncurses development libraries. Running nvtop launches the interactive UI showing up-to-date graphs and process lists.

In summary, NVTOP is a lightweight, terminal-based, real-time GPU monitor tool that offers a user-friendly and highly interactive experience for tracking NVIDIA GPU and accelerator performance on Linux. It enhances system observability for professionals and enthusiasts working with GPU-intensive applications.
