[one-users] network boot with xen

[Michaël Van de Borne]

Hi again,

still about the network boot:
Correct me if I'm wring but the first thing to do when booting from the 
network is to send a DHCP request (to get an IP and the address of the 
TFTP server), right?

Unfortunately, using tcpdump, I cannot see any DHCP request getting out 
from my machine (either from the virtual NIC virbr0, nor from the 
physical eth0).

Here is the tcpdump command I use:
sudo tcpdump -i virbr0 -n port 67 and port 68
or
sudo tcpdump -i eth0 -n port 67 and port 68

Here is the very basic VM template I use:
CPU=0.5
NAME=centos-ks
DISK=[
   SOURCE="/srv/cloud/one/var/centos-ks/centos-ks.img",
   READONLY=no,
   TARGET=hda ]
FEATURES=[  ACPI=no ]
MEMORY=300
NIC=[ MAC    = "50:20:20:20:20:20",
         BRIDGE = virbr0 ]
OS=[  BOOT=network ]

Can anyone tell me how to get a DHCP request sent from the booting VM?

PS: the disk is empty cause I'd like to kickstart the VM from scratch at 
bootup, I don't know if it matters)

cheers,

michaël
