# 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 KubeVirt (enp2s0) and the same
|
|
# device ordering.
