Setup:~

: Update System
➡️sudo apt update && sudo apt upgrade -y
Install KVM and Required Packages
➡️sudo apt install -y qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager
virtinst
✅ This installs:
👉qemu-kvm: the hypervisor
👉libvirt: for managing KVM
👉bridge-utils: for networking
👉virt-manager: optional GUI (can be skipped on headless)
👉virtinst: command-line VM creation tool
Verify KVM Installation
Check if your system supports virtualization
➡️egrep -c '(vmx|svm)' /proc/cpuinfo
Check KVM modules:
➡️lsmod | grep kvm
Check libvirtd is active:
➡️sudo systemctl status libvirtd
Add Your User to libvirt & kvm Groups
➡️sudo usermod -aG libvirt $(whoami)
➡️sudo usermod -aG kvm $(whoami)
👉 Logout and log back in to apply group membership.

Set up the cockpit :

Install & Enable Cockpit (Web UI)
➡️sudo apt install -y cockpit cockpit-machines
➡️sudo systemctl enable --now cockpit.socket
✅ cockpit-machines gives you GUI to manage KVM virtual machines.
Open Cockpit Web UI
Cockpit runs on port 9090.
Open in browser:
https://your-server-ip:9090
Log in with your Ubuntu user credentials (must be in sudo or libvirt group).
✅ Enable Bridge Network
need to create a Netplan File for bridge adaptor I past on down check ⬇️ at setup files.
Apply the New Network file
➡️sudo netplan apply
Confirm Bridge is Up
➡️ ip a
✅ : Use Host Bridge (recommended for real LAN access)
📁 1. Create XML file
Create a file kvm-bridge-br0.xml
---- I past that file at setup file section check ⬇️
📌 2. Define and Start the Bridge in libvirt
➡️sudo virsh net-define kvm-bridge-br0.xml
➡️sudo virsh net-start br0-net
➡️sudo virsh net-autostart br0-net
✅ Now this network br0-net is:
Using your host’s br0
Auto-starts on boot
Visible in Cockpit and virt-manager
Available in virt-install as --network network=br0-net
