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...

Tailscale: A Simpler, Smarter Way to Connect All Your Devices

on




Tailscale creates a private, encrypted network between your devices using WireGuard under the hood. Instead of “a VPN but complicated,” it acts more like:

  • a mesh of private tunnels
  • with identity-based access (your Google / Microsoft login = your authentication)
  • and automatic NAT traversal (no port-forwarding nightmares)
  • plus support for basically every platform on Earth

Everything becomes part of your personal tailnet, your own secure space.

1. Create your tailnet

  1. Go to https://tailscale.com/
  2. Click Sign Up
  3. Choose the identity provider you want (Google, Microsoft, GitHub, Apple ID, etc.)

That’s it. Your tailnet exists.

2. Install Tailscale on your first device

On Windows

  1. Download the installer from:
    https://tailscale.com/download
  2. Run the .msi
  3. Sign in
  4. Approve the device
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up

Then sign in via the browser page that opens.

3. Add your second device

Once signed in, both devices will now appear in your tailnet dashboard.

You can access the admin page here: https://login.tailscale.com/admin/machines

You’ll see a list like:

Jason-PC
Pixel8Pro
LinuxServer
Tablet
RaspberryPi

Each device gets a private IP like:

100.x.x.x

Tap or click a device — you can now connect to it directly.

From one device, open a browser and type the other device’s Tailscale IP, e.g.:

http://100.80.0.12:3000

or ping it:

ping 100.80.0.12

5. Enable "MagicDNS" (Optional but Recommended)

MagicDNS lets you access devices by name instead of IP addresses.

Example:

http://jason-pc.tailnet
http://pixel8pro.tailnet

Enable it:

  1. Go to https://login.tailscale.com/admin/dns
  2. Toggle MagicDNS ON
  3. Save

6. Set Up an "Exit Node" (Optional)

To turn a device into an exit node:

On Linux:

sudo tailscale up --advertise-exit-node


7. Network Sharing and Subnet Routers

If you have a home LAN with devices you can’t install Tailscale on (smart TVs, NAS units, printers), you can expose the whole subnet.

Example:

sudo tailscale up --advertise-routes=192.168.1.0/24

Then approve the route in the admin page.

It’s a clean way to access your whole home network from anywhere.
