KVM Bridge Networking Tutorial | Ubuntu 25.10 VM Gets Real LAN IP on Fedora 43
KVM bridge networking tutorial.
Ubuntu VM gets a real LAN IP using a bridge interface on Fedora host.
In this tutorial I demonstrate how to configure *bridge networking in KVM* so that a virtual machine receives a real IP address from the router.
The host system is Fedora 43 Workstation and the guest system is Ubuntu 25.10 running in KVM using virt-manager.

Do not run scripts on systems you do not own or manage.

In this video you will learn:
• how to create a Linux bridge (br0)
• how to connect a VM to the bridge network
• how to verify that the VM receives a LAN IP from the router
• how to test connectivity using ping and SSH
Host OS: Fedora 43 Workstation
Guest OS: Ubuntu 25.10
Virtualization: KVM + virt-manager
Commands shown in the video:
ip a show br0
ping -c 3 192.168.x.x
ip route
arp -a
The Ubuntu VM behaves like a real device in the local network and can be accessed via SSH from the host.
