Which network card type does Red Hat recommend to use for the guests running on RHEV?
Issue
- In the Administration guide there's mention of three different network card types that's possible to use with RHEV 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
- How does one decide which of the three cards to choose.
- Is it that different operating systems will perform better with one over the other?
- What are Red Hat recommendations on this?
Environment
- Red Hat Enterprise Virtualization 3.0, 3.1, 3.2
