[Xen-users] Network problem with HVM Windows

[Maximilian Wilhelm <max@xxxxxxxxxxx>]

Hi!

I've setup a HVM domain running Windows[tm] Server 2003.
The installation was no problem and when connecting from Dom0 to the
Windows machine via rdesktop everything is fine.

The problems show up when connecting from others host of the network
to the Windows server or from the Windows server to the internet.
Most times the connection failed totally, sometimes it's boring slow.

When trying to open any website on the Windows machine while sniffing
on the bridge or real ethernet interface, I can see packets going out,
but no answers coming in.

---snip---
kernel = "/usr/lib/xen-3.0.3-1/boot/hvmloader"
device_model='/usr/lib/xen-3.0.3-1/bin/qemu-dm'
builder='hvm'

memory = 512

name = "win_2k3"

vif = [ 'type=ioemu, mac=00:de:fa:ce:d0:23, bridge=br1' ]

disk = [ "phy:/dev/vg_shsserver2/lv_win2k3,hda,w",
         "file:/home/win2k3.iso,hdc:cdrom,r" ]

boot="c"

sdl=0
vnc=1
vncviewer=0

localtime=1

apic=0
acpi=0
---snip---


I'm a bit surprised that this configuration brings up two interfaces
associated with the windows machine which than are connected to the
bridge:

---snip---
shsserver2:~# brctl show
bridge name     bridge id               STP enabled     interfaces
br1             8000.00304835cd62       no              eth0
                                                        tap0
                                                        vif19.0
---snip---

The IP of the Dom0 machine is also configured on the bridge interface
as both belong to the same small network. All services offered from
Dom0 are running fine.

Any hints welcome!

Ciao & Thanks
Max
