RE: [Xen-devel] Networking not working

["James Harper" <JamesH@xxxxxxxxxxxxxxxx>]

I had this problem when eth0 (tied to br0) was not in promiscuous mode.
The TLAN driver has a bug where PROMISC mode gets reset when the link
comes up (eg when you pull out the cable and put it in again). My
startup would go like this:

. modprobe tlan for eth0
. create bridge (sets PRMOMISC on eth0)
. tlan finishes initialisation, detects link, and resets PROMISC

I created a kernel patch to fix it but it seems to have been largely
ignored. I work around it by putting a sleep in the network interfaces
config and having a cron job set PROMISC every 5 minutes in the unlikely
event that it gets reset.

Try the following:
ifconfig eth0 promisc
(or whatever your Ethernet interface is)

If that fails, try
ifconfig eth0 -promisc
ifconfig eth0 promisc
in the case where the driver thinks it's already in promiscuous mode and
doesn't set the hardware accordingly
