The following emulated network interface cards are available for Xen HVM guests in Xen 3.4:
- e100
- e1000
- rtl8139
- ne2k_pci
- pcnet
Emulation is done by Qemu-dm running for each Xen HVM guest. Intel e1000 is known to be the best performing emulated NIC. Even faster is to use PV-on-HVM drivers, which totally bypasses emulation.
