Yes, it's been happening for a long time, and it appears to be a 
problem with the Vista driver for the RealTek 8139(?) network adapter 
and the compatibility with the QEMU implementation of 8139. Someone 
reported that Win2K3 driver can be made working, but I've not tested 
this myself.

What issues are you having?  And what version of Xen?  32bit Vista's RX
path didn't work at all with the emulated rtl8139 before about three
weeks ago (cset 15596 of xen-unstable).

There is a CRC bug in the RTL8139 implementation in the QEMU used in 3.1
There have been discussions of this on the QEMU list, as well.

We have a patch for 3.1, but have not ported it forward to unstable yet, 
since unstable is using a newer version of QEMU.

If there is interest in seeing the 3.1 patch, I'd be happy to post it.

I was trying on a 3.04 based system with a lot of post 3.04 features backported. Tim, is the problem fixed on cset 15596. Would you know which cset fixed the problem?

Yes, 15596:d99903a98ad0 fixes the Vista issue.  You should probably take
15595 as well, which fixes an issue for older Windows versions.  They
should backport easily to older qemu-dm versions.

Cheers,

Tim.

Yes; I fixed it in unstable and sent the patch upstream to qemu-devel.

If your patch covers more than the one in -unstable, I'd be very
interested in seeing it.

It looks like its the same patch as 15596.
We must have pulled the patch from the qemu list, without realizing it 
was in unstable.
