<div>Sorry for the mail-flood but I finally got It working and I think someone else could find this useful.</div>
<div><br>The root of the problem was that no peth0 interface was created on Dom0, after reading xensources wiki and doing "brctl show" made it clear.</div>
<div>I still dont't know why this was happening but I think It was somehow related with SELinux or netplugd.</div>
<div>I reinstalled FC5 without SELinux nor iptables, and xenguest-install.py just worked as expected, and the DomU guest got DHCP and reached the NFS mount-point exported in the Dom0 Itsef.</div>
<div> </div>
<div>Maybe some smart developers should take look at this.</div>
<div> </div>
<div>regards.</div>
