Apologies if this is trivial and an FAQ. Google search
hasn''t helped.
I have been unsuccessful in getting eth0 interface up in
dom0. My linux installation is FC3 and I get my address via
DHCP. I am running Linux 2.6.11-xen0. I see the following
steps recommended in the bridge-utils HOWTO page
1. Zero IP the interfaces. The bridge needs the network
devices to be operational, but without TCP/IP running on
them.
# ifconfig eth0 0.0.0.0
2. Create the bridge interface.
# brctl addbr mybridge
3. Add interfaces to the bridge.
# brctl addif mybridge eth0
[I believe steps 2 amd 3 will be done by executing
xend start. I verified this by running ''brctl show''
after I ran ''xend start'']
4. Put up the bridge.
# ifconfig xen-br0 up
Now that I have the bridge up, I tried running
ifup eth0
to get an IP address.
I get the following:
"Determining IP information for eth0...PING
<my.dhcp.server.address> from
<what-I-think.is-the-IP.address.I-was-assigned>: eth0"
[usual ping statistics stuff]
failed.
I suspect I am close but not there. Can someone provide the
nudge please?
Thanks,
Bharadwaj

You''ll need to create an appropriate ifcfg-mybridge file then ''ifup mybridge''.

Hi Ian, Thanks for your reply. However, I am still unable to get my network interface up in dom0. Here is what I did: I created a /etc/sysconfig/network-scripts/ifcfg-xen-br0 as you suggested. # more /etc/sysconfig/network-scripts/ifcfg-xen-br0 DEVICE=xen-br0 BOOTPROTO=dhcp ONBOOT=no TYPE=Ethernet DHCP_HOSTNAME=<myhostname> USERCTL=no PEERDNS=yes IPV6INIT=no [I also needed to modify /etc/sysconfig/network-scripts/network-functions so that the device xen-br0 is not picked as xen but as xen-br0.] Anyway, once dom0 booted, I do the following : # ifconfig eth0 0.0.0.0 up # xend start # ifup xen-br0 I see dhclient running (ps) but I get ======Determining IP information for xen-br0... xen-br0 failed ===== What am I missing? I verified that eth0 interface would come up as expected and I get an IP address when booted with standard FC3 Linux kernel.
