virtualbox client can't netboot pxe-e74 Bad or missing PXE menu and/or prompt information

MarcB · Dec 1, 2016, 7:31 PM

Server

FOG Version: 1.2.0, not serving dhcp, but using dnsmasq. Works fine with non-virtual client machines.
OS: ubuntu 14.04.5

Client

Virtualbox

Description

Virtualbox starts, gets a dhcp address from the cisco switch, but doesn’t seem to get more info fog server. Error is: pxe-e74 Bad or missing PXE menu and/or prompt information

george1421 · Dec 1, 2016, 1:39 PM

is the FOG server, dhcp server and target computer (vm) on the same subnet (broadcast domain)?

<edit> Wait, I see it works correctly with non-virtual (vbox) machines. The question is what is the virtual box vm doing that is different?

@george1421 maybe natted net when it should be bridged?

I guess I need to mess around with virtual box for a bit, I only work with VMWare any more.

To add PXE boot capabilities to an Oracle VirtualBox machine you must add a version-matching ExtensionPack (.vbox-extpack)).

For Oracle VirtualBox 5.1.10, download from Index of /virtualbox/5.1.10 then add it to your Oracle VirtualBox via menu Preferences > Extensions

Hi,

i have a working UEFI PXE Boot with any normal Computer but howto get Network booting enabled after enabling EFI in Virtualbox?
When i set a VM EFI enabled and Boot device to Network it always just boots into a PXE Shell.

When i Press F12 while booting to get into the boot menu i cannot see a network device to boot from:

When trying to add that boot option i just get an empty windows:

Howto tell the machine to boot from network?

Regards X23

The VM is definitely bridged, and is getting an address on the appropriate network. The Oracle VM VirtualBox Extension Pack shows up in Preferences as “Active” and is the same version as the Virtualbox Software app.

As I said earlier, non-virtual machines get an address from our dhcp server, and are directed to the FOG server by dnsmasq. Here’s the logging that takes place as the VM tries to boot (I’m hitting “F12” when the machine boots).

Oh, and for the record our fog server is a physical box (non-vm). The only VM in question is the one I’m trying to boot from the fog server.

george1421 · Dec 2, 2016, 9:08 PM

@MarcB Is your target machine, dnsmasq server, and dhcp server on the same subnet (broadcast domain). If so then we should probably get a pcap file of of this pxe boot to error message.

install tcpdump on your fog server
start tcpdump with this command line at the fog console prompt tcpdump -w output.pcap port 67 or port 68 or port 69 or port 4011
then pxe boot the target computer (vm) to error
once at the pxe error press ctrl-c to stop tcpdump
post it here for review.

This will tell us what your dhcp server/dnsmasq server/ and what your client is asking of the tftp server.

Thanks again for your help with this issue.

I thought I should add that, with the exception of bridged networking, all other settings for virtualbox client are the default settings for an ubuntu 64-bit install.

Here’s the output file of the tcpdump command (run as sudo):

@MarcB would you mind posting the pcap file as an attachment I can’t load what was posted into wireshark to look at it. I’m not smart enough to read the pcap in text form.

Sebastian Roth · Dec 3, 2016, 8:59 PM

This somehow sounds as if virtualbox client is not happy with option 43 being sent by dnsmasq in frame number 3. Quiet strange I find. Can you please post your dnsmasq config? Maybe try stripping options pxe-service and/or pxe-prompt from it - if set.

I have 2 lines with that specify pxe-service options and tried commenting them both out. I also commented out pxe-prompt. None of these changes to my ltsp.conf file allowed the VM to netboot.

I’ll attach the ltsp.conf file here.0_1480949862710_ltsp.conf

Thanks for your help.

I had tried to display everything I saw when I opened it up in Wireshark, but maybe I missed something.

There’s some information in the pcap that I can’t seem to scrup. I found an app called tracewrangler that I’ll try to work with to prepare the pcap file.

Thanks again,

Marc

george1421 · Dec 5, 2016, 4:21 PM

@MarcB If you could post the actual pcap file and I’ll take a look at it.

MarcB · Dec 5, 2016, 6:55 PM

@george1421

Here’s the anonymized pcap. Hopefully it still provides all the relevant information you need.0_1480964109034_output_anon.pcapng

Sebastian Roth · Dec 6, 2016, 6:00 AM

@MarcB In that new pcap file I see “boot file name” being empty in all DHCP answers. Therefore the client does not know which file to load. In the config you posted I see:

...
dhcp-boot=undionly.kpxe,,FOGserverIP
...

Please change this to (make sure the IP is the correct one pointing to your FOG server):

...
dhcp-boot=undionly.kpxe,10.202.47.230,10.202.47.230
...

I usually put the IP address twice, first as server name and the later one to point to the actual IP - see the man page for details about all the options.

MarcB · Dec 6, 2016, 10:31 PM

@Sebastian-Roth

VMs are still not able to continue the netboot process with the additional specification of the fog server IP. I just used the IP address twice, as this fog server is not available vi dns (so I didn’t use the name).

Thanks for the suggestions though.

@george1421

I tried the simplified ltsp.conf file you referred me, but that also does not work.

Thanks again,
Marc

george1421 · Dec 6, 2016, 4:46 PM

@MarcB Please capture another pcap file with the updated config file.

I can say I just loaded virtual box + extension pack on my zorin (ubuntu based) laptop and I was able to pxe boot from my home fog server running dnsmasq. I just tried in bios (legacy) mode and it worked as it should. So I can say it does work.

MarcB · Dec 7, 2016, 5:58 PM

@george1421

Cool - I’m glad it’s working for you - there’s hope! What is your OS for FOG (and dnsmasq)? Are you using the simplified ltsp.conf file you posted previously?

Is your Virtualbox 5.1.10? Were there any options in VirtualBox you had so specify (that I might have missed)?

Here’s the logs from the fog server when the VM is netbooted:
