[Xen-users] M2N32, suse 10.3 and network problem

[Chris Epicier <seuchato@xxxxxxxx>]

Hi 

I have an Asus M2N32 WS Pro, 4G Ram, AthlonX264 4600+.
I Installed SuSE 10.3 (64bit) on Dom0, LVM on Raid 5.
All domU's boot off LVM, using same Suse 10.3. 
I have a firewall (fw) domU running shorewall and a
domU name-dhcp-server (nds). Somewhere in between 10
and 16 hours the network stalls. In dns, I can see
dhcp queries and offers, but these never make it to
the clients in the lan. if I try pinging the domU's I
just get no reply at all. If I shutdown and boot the
domU's again everything runs again.

I considered running "ethtool -K eth0 tx off" on one,
all domU's without success. First I had delegated one
of the on board nics (mcp55, forcedeth) from dom0 and
forwarded to domU fw. That gave some mm.c
errormessages. Thus I now have a pci USB contrioller
with attached NIC delegated from dom0 to domU fw. 

Here are the configs for fw
Linux fw 2.6.22.13-0.3-xen #1 SMP 2007/11/19 15:02:58

kernel = "/boot/vmlinuz-xen"
ramdisk = "/boot/initrd-xen"

vif = [ 'mac=aa:cc:00:00:00:C2, bridge=xenbr0' ]
disk = [ 'phy:system/fw,sda1,w' ]

extra = "3 xencons=tty"

Can any one help me here? How can I trace/solve that
problem?
