Re: [Xen-devel] [Q] eth0 not up on dom0

[Bharadwaj Yadavalli <bharadwaj.yadavalli@xxxxxx>]

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.

Thanks for your help once again,

Bharadwaj
