Hi Folks,
I''ve tried to compile/install the xen-unstable-src.tgz from today
and it works fine (at least xend start) but I can not start the network,
not even for Domain-0! I''m using the Broadcom Corporation NetXtreme
BCM5782 Gigabit Ethernet controller.
(I''ve recompiled the xen kernel after the ''make
world'' to get the
smbfs module, but I don''t think the kernel is bad since it works fine
if I start it outside from xen)
What could I try next?
My settings are:

It won''t help you communicating with the outside world. Configure xen-br0 instead (you broadcom is probably eth0, belonging to that bridge) like you did with veth0 before, and UP it. ip addr del 15.136.125.167/21 dev veth0 ip link set veth0 down ip addr add 15.136.125.167/21 dev xen-br0 ip link set xen-br0 up ip route add default via 15.136.127.254 /nils.> end of dmesg output: > > device vif0.0 entered promiscuous mode > xen-br0: port 1(vif0.0) entering learning state > xen-br0: topology change detected, propagating > xen-br0: port 1(vif0.0) entering forwarding state > bridge: can''t decode speed from eth0: 65535 > device eth0 entered promiscuous mode_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hi Nils, Thanks for your help. Still it did not work with xen-unstable-src.tgz but I''m fine with it since I''ve now got it running with xen-2.0-testing-src.tgz Yes I''ve compiled my tg3 network module otherwise I would not even be able to ping my own IP. Configuring xen-br0 did not help anything. Actually the problem was already before I started xend so even without the bridging stuff. With my plain eth0 and lo in the ifconfig output I already miss the ''RUNNING'' flag for eth0. I''ve tried to add my gateways MAC into /etc/ethers then a ping on it looked like this: # ping 15.136.127.254 PING 15.136.127.254 (15.136.127.254) 56(84) bytes of data. ping: sendmsg: No buffer space available ping: sendmsg: No buffer space available Don''t know what is wrong with my network, but I can live with it as long as xen-2.0 works now. I''ll try xen-unstable again some day in future..
