Overview
This template ships a clean ubuntu-24.04 image, ready to reference from any vm block. vmlab keeps one copy of the backing file on the host and boots each guest as a qcow2 linked clone, so a lab of ten machines costs little more than one base image on disk.
Reference it in a lab

vm "guest" {
template = "riscv64/ubuntu-24.04"
nic { segment = "lan" }
}
