This project provides a comprehensive, dialog-based Bash installer that automates the setup of a Rocky Linux 9.x server as a secure, VLAN-aware KVM virtualization host.

Validates and enforces static IP configuration
Configures Chrony NTP using up to 3 user-defined servers Updates the system to latest packaging via dnf Installs all necessary packages for KVM, libvirt, and Cockpit
Enables and starts libvirtd, fail2ban, and cockpit.socket
Prompts for trunk interface and VLANs to bind VMs
Sets up bridges for each VLAN with STP disabled (switch handles STP)
Migrates your static IP to a native VLAN bridge for management isolation If the /home directory has been set as a separate mapper by the OS installation, the script will remap and reclaim space from home into root, and recreate the /home directory
Removes auto-run installer from .bash_profile
Cleans up installer files. If running from the console will reboot. If from SSH you must manually reboot on the console (due to network changes)

Result: You get a fully-functional, secure KVM server ready for virtual machine deployment, with VLAN isolation and management separation.

You should only be using (1) physical interface that will be configured for trunking by your network swtich equipment, by deafult. You do not have to run any updates on the server, just a simple install from the ISO (Install, reboot). The Script/Installer will take care of the rest.

Open the EASY_INSTALL File and run the contents inside from the REPO itself Or copy this line from here and run in terminal or SSH session:

dnf -y install wget && cd /root && bash <(wget -qO- https://raw.githubusercontent.com/fumatchu/KVM/main/KVMInstall.sh)

This will download and bootstrap the installer to the system

Network changes will disconnect your active session at the end of the script if using SSH

Use the "Virtual machines" navigation option on the left and make sure you are directly attaching the machines to the VLANs you want
