Vista/rtl8139 broken?

[Alistair John Strachan <alistair-T7eSMZptz7IqdlJmJB21zg@public.gmane.org>]

Hi,

I've been using ne2k with BSD/Linux/WindowsXP just fine with 
KVM-35/2.6.23-rc2, but when I try to run Vista, which doesn't support the 
ne2k any more, I tried switching to the rtl8139 emulation.

I observed that the rtl8139 emulation works fine in WindowsXP, so it's not 
broken. But it does not seem to work in Vista (x86). The host is AMD64/SVM. 
The way that it doesn't work is that no packets are sent/received over the 
interface, so the device does not route.

The only difference between XP and Vista's KVM startup is that for Vista I 
enable ACPI (necessary to install).

WindowsXP -->
kvm -no-reboot -localtime -no-acpi -m 256 -hda $IMAGE \
    -net nic,model=rtl8139 -net tap,script=/etc/kvm/kvm-ifup $*

Vista -->
kvm -no-reboot -localtime -m 512 -hda $IMAGE \
    -net nic,model=rtl8139 -net tap,script=/etc/kvm/kvm-ifup $*

The problem seems to be similar to a QEMU endian bug from some time ago, but I 
don't think that's the problem here. It looks like it's some sort of 
incompatibility between Vista and the rtl8139 emulation.

Any ideas? Does ACPI have anything to do with it?
