I'm not sure what a screen shows while a machine PXE boots. (Sorry, I'm blind.) So this may be a dumb suggestion but you can tell what files a machine is asking the tftp server for during a PXE boot by turning on verbose mode on the tftp server. With tftpd-hpa, you add -vvvv to the end of the TFTPD_OPTIONS line at the end of the file /etc/defaults/tftpd_hpa. Then you can do "tail -f /var/log/syslog" on the tftp server and watch the client ask for each file in turn durng a pxe boot. It's quite entertaining, actually. :-)

Hi Chris,

Thomas went through all steps with me for a couple of days.. and we both come the conclusion
that Virtual Box must be the culprit.
I’ve a faiserver as guest and want to pxe boot another guest; the client gets an IP address but not the pxelinux.0 Connecting locally on the faiserver with a tftp client the download works, hence the tftp server works.

Does anyone know about this problem with/among VBox guests among each other?

I checked all kinds of network VBox offers: Nat, Nat network, Internal Network, Bridged.. no way.

Thanks so much!

Best,
Chris

I'd confirm your findings: I tried a similar setup a while ago (FAI 4 server and FAI client as VB guests on an OpenSuSE 13 host) with a myriad if different VB network settings and none worked. I finally gave up after a few days. However it worked fine, when having the FAI server as VB guest and the FAI client being a real ("metal") PC in our network. I consluded, that the internal VB PXE/TFTP/Bootp server was "somehow" interfering with FAI's.

My conclusion: Save your energy and don't try this kind of setup :-)
