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.
