Unless I'm mistaken, e1000 is a conventional PCI device, with
e1000e being the PCI Express equivalent.

Most VirtIO devices, including virtio-net, show up as either
conventional PCI or PCI Express based on the slot they're plugged
into, so if you have

  -device virtio-net-pci,bus=pci.0

it will show up as a conventional PCI device but if you have

  -device pcie-root-port,id=pci.1,bus=pcie.0 \
  -device virtio-net-pci,bus=pci.1

instead it will show up as a PCI Express device.
