FYI: fixing Vista networking with rtl8139 + KVM
A Fedora user reported that Vista networking isn't working with KVM[1] and pointed to the Wiki
http://kvm.qumranet.com/kvmwiki/Vista_Networking_Workaround
FYI, a patch from Xen was merged into upstream QEMU to fix this problem with rtl8139 a week or two back and works nicely with KVM+Vista...

..avoiding need for messing around with ne2k drivers as mentioned in the wiki

does this means that in general use the ne2k driver is a better choice? anyway is there a suggested network driver for the guests?

No, it means I need to merge qemu-cvs.
rtl8139 performs faster than ne2000.

But adding CRC computing in RTL839 should have some impacts on performance.

It's probably negligible since the copy has placed the packet in the cache.

No, ne2k is an awful choice. It has worse performance than rtl8139 and does not do link state reporting so things like network manager won't be able to automatically configure the NIC in a guest. rtl8139 is the preferred choice and in Fedora we have patched Xen, QEMU & KVM so they use rtl8139 by default
