Is there a list of NIC models that I should use with various HVM guests in Xen 4.0? Is there even a list of possible choices for the model=field? I'm planning on running both Windows and FreeBSD guests on the particular Xen box that I'm configuring now, and ideally I'd like a setting that can work on both of them and get me gigabit speeds without a lot of extra hassle loading special drivers (similar to VMware's e1000 NIC option). Any suggestions?

The vif line I'm currently using in my config is:

vif = [ 'type=ioemu,bridge=eth0,model=ne2k_pci,script=vif-ovs' ]

This works in my Windows XP SP3 VM, but is only recognized as a 10Mbit interface. Changing to model=e1000 or model=i82557b resulted in Windows not being able to find a driver for the NIC.

Here is the answer for XEN 3.4 from the XEN-WiKi. If you read this you will find that it depends on the capabilities of qemu-dm - I hope this helps for 4.0.

For Windows I would recommend using a PV driver.

Thanks Nils. I've tried several of the different options for PV drivers, and have yet to find one that could in any way qualify as stable in Windows XP 32bit. – Jed Daniels Sep 13 '11 at 23:45
Propably this one? there was an article a while back in the german c`t magazine describing that driver in a 0.9 version. On Heise I found another link leading to XEN Cloud PV drivers for Windows. On Heise it seems that you can use that driver with the OpenSource XEN 4, too. – Nils Sep 14 '11 at 21:08
+1 for GPLPV drivers on Been using them for 3.5 years (really, first bootup was 01/2009) on some Windows XP 32bit HVM systems without a single itch. – Luke404 Aug 6 '12 at 21:00
@JedDaniels it seems I am not the only one who used the GPL-PV-drivers in production. – Nils Aug 6 '12 at 21:11
