A Red Hat training course is available for Red Hat Virtualization

9.5. Network Devices

Red Hat Virtualization is able to expose three different types of network interface controller to guests. The type of network interface controller to expose to a guest is chosen when the guest is created but is changeable from the Red Hat Virtualization Manager.
  • The e1000 network interface controller exposes a virtualized Intel PRO/1000 (e1000) to guests.
  • The virtio network interface controller exposes a para-virtualized network device to guests.
  • The rtl8139 network interface controller exposes a virtualized Realtek Semiconductor Corp RTL8139 to guests.
Multiple network interface controllers are permitted per guest. Each controller added takes up an available PCI slot on the guest.
