Host a Simple Python App on a Virtual Machine (Step-by-Step)

Serve a Python App from a VM: From Local Server to Public Access In this guide, we’ll deploy a simple Python HTTP server on an AlmaLinux virtual machine and explore how network traffic flows from the VM to the host machine and beyond. By the end, you’ll be able to access your app from your local network and from external devices using a public tunnel. Let's learn how to: Set up a Python HTTP server on a VM Access the server from the host machine Expose the VM to external devices via Localtunnel Understand the traffic flow from client to VM In this setup, the AlmaLinux VM runs a Python HTTP server, the Fedora host acts as a KVM/QEMU host and NAT gateway, and the smartphone simulates an external client. We’ll show how to make the server accessible locally and over the internet using a tunnel. 1️⃣ Environment Setup AlmaLinux 10 VM (Guest) IP: 192.168.122.88 Runs the Python HTTP server Fedora Host IP: 192.168.0.136 Acts as KVM/QEMU host and NAT gateway Smartphone / External Device Connecte
