# Generate a libvirt domain XML for a VM that behaves like a real machine
# (BIOS/q35, virtio disk, bridged NIC, VNC display).
#
# The NIC is pinned to q35 PCI bus 0x02 and the disk to bus 0x04 so the guest
# sees the same interface name it did under the former KubeVirt (enp2s0) and the same
# device ordering.
