Description Daniel Berrange 2007-08-08 15:22:42 EDT
Description of problem:
There have been a number of messages on community mailing lists saying Xen 3.1
HVM networking does not work with Vista. Upstream XenSource have just confirmed


"32bit Vista's RX path didn't work at all with the emulated rtl8139 before about
three weeks ago (cset 15596 of xen-unstable)."

changeset:   15596:d99903a98ad0

[HVM] Qemu rtl8139: correct rx CRC calculation
Signed-off-by: Tim Deegan <Tim.Deegan@xensource.com>

We need to double check this in RHEL-5.1 since our QEMU binary is based on Xen
3.1 and thus does *not* have this fix.

Version-Release number of selected component (if applicable):
Any xen prior to changeset 15596
