Fedora Single Node

The lab runs in a Docker container with two QEMU VMs inside.
The VM has three interfaces:
- br1 (191.0.0.0/24): For ssh.
- br2 (192.0.0.0/24): For testing.
- br3 (193.0.0.0/24): For testing.
Each VM has the below disks:
- /dev/sda: (Fedora Server QCOW) Boot and filesystem.
- /dev/sdb: For testing.
- /dev/sdc: For testing.
