Hi,
I''m having a problem getting Xen networking (bridging) to work with my
domUs. I am using Xen 3.0.2 with Gentoo 2006.1 as dom0 (2.6.16.28-xen).
The machine is a newer Dell with a Pentium D (VMX enabled) processor. It
has one physical ethernet interface (Tigon3). The networking works fine in
dom0 (I''m using SSH right now), but I can''t get anything in my
domUs. I
can''t obtain an IP address in any of the domUs and setting the IP
manually
doesn''t help. I''ve even tried setting a static ARP entry on
dom0 to one of
the domUs and I can''t get to any of them that way either. All of the
domUs
are HVMs and some are running Windows XP and some are running OpenBSD. All
of the domU config files have ne2000=0 (using pcnet NIC).
It seems all of the virtual interfaces for the domUs are dropping all of
the TX packets:

And the bridge looks okay:
xen_test ~ # brctl show
bridge name bridge id STP enabled interfaces xenbr0
8000.feffffffffff no vif0.0
peth0
vif23.0
vif10.0
vif11.0
vif12.0
vif24.0
All of the domUs are similar to this (just different IDs of course):
xen_test ~ # xm network-list 24
Idx BE MAC Addr. handle state evt-ch tx-/rx-ring-ref BE-path 0 0
?? 0 1 -1 -1 /-1
/local/domain/0/backend/vif/24/0
Also, when doing a ''brctl showmacs xenbr0'' it doesn''t
show any of the
domU''s MAC addresses (maybe this is normal):
xen_test ~ # brctl showmacs xenbr0
port no mac addr is local? ageing timer

I guess I''m a bit stumped. I don''t have iptables installed.
I''d like to
get this bridging method working. I''ve seen that you can also do
networking using the routing method, but I guess I''d still like to find
out why this isn''t working. This has gotta be something simple
I''m
missing. I''ve attached my dom0 Linux kernel .config just in case.
Any help is greatly appreciated.
Thanks for your time.
