Re: [Xen-users] VM nic not taking IP address (fwd)

[Tom Brown <tbrown@xxxxxxxxxxxxx>]

I wouldn't normally send a generic sys admin type response to the list,
but when people install broken challenge/response systems, there isn't
much alternative.

Subject: Re: [Xen-users] VM nic not taking IP address


sounds like the domU doesn't know it is supposed to configure the extra
two nics... I do all my config by hand and would be looking for

   [root@cf2 /etc/sysconfig/network-scripts]# ls ifcfg-eth*
   ifcfg-eth0
   [ on your box there should be an ifcfg-eth1 and ifcfg-eth2
   files]

but you may admin your system differently .... on redhat there tends to be
an ifup script, does ifup eth1 do anything? and what does the output from
"/etc/rc.d/init.d/network start" look like?
