PXE Boot problem

[Katarzyna Myrek]

Hello

I am trying to install FAI (version 4) for the first time. I did everything
according to the manual but I have problem booting clients with pxe.
Error in client: Could not chain image: Operation not supported".

I have DHCP configured with demohost:

cat /etc/dhcp/dhcpd.conf
deny unknown-clients;
option dhcp-max-message-size 2048;
use-host-decl-names on;


subnet 192.168.10.0 netmask 255.255.255.0 {
  option routers 192.168.10.1;
  option domain-name "FAI4";
  option domain-name-servers 192.168.10.250;
  option time-servers 192.168.10.2;
  option ntp-servers 192.168.10.2;
  server-name FAI4;
  next-server FAI4;
  filename "fai/pxelinux.0";
}
**
host demohost {
  hardware ethernet 52:54:00:17:8f:0e;
  fixed-address 192.168.10.11;
  option host-name "demohost";
}


But when I try to run *fai-chboot *I get an error:
fai-chboot -IFv demohost
Booting kernel vmlinuz-2.6.32-5-amd64
 append initrd=initrd.img-2.6.32-5-amd64 ip=dhcp
    FAI_FLAGS=verbose,sshd,createvt

fai-chboot: unknown host: demohost

I am missing something??

Thanks,
Olivia
