Hi,

I am trying to use iPXE in a VM running in VirtualBox. The problem is
that iPXE can not get DHCP.
I am using the latest version of iPXE (b6cad3c0eb72e99d8ae5e6944ec8e9b7c5acecfa)
VirtualBox 4.0.6 r71344
Ubuntu 11.4 64bit
The DHCP/tftp server is OpenWRT Backfire (10.03.1-rc4, r24045)
dnsmasq --version
Dnsmasq version 2.55  Copyright (c) 2000-2010 Simon Kelley
Compile time options IPv6 GNU-getopt no-DBus no-I18N DHCP TFTP

Here is the dnsmasq configuration (I've removed dhcp-host entries):
/usr/sbin/dnsmasq -K -D -f -y -Z -b -E --enable-tftp -s lan -S /lan/
-l /tmp/dhcp.leases -r /tmp/resolv.conf.auto --tftp-root /tftproot
--dhcp-boot undionly.kkpxe --stop-dns-rebind
--dhcp-range=lan,192.168.1.100,192.168.1.250,255.255.255.0,12h -2
'eth1'

Attached is the capture made with:
tshark -w /tmp/iPXE-DHCP-problem.cap -pi eth1 port bootpc or port tftp

If I boot from a physical computer, I have no problems. I do not
understand why iPXE is not receiving the DHCP responses.

Thank you,
Mircea
