PXE Booting ESXI 6.7u2
-
It is uefi. (It’s a T420 Thinkpad TP00015A)
-
@nexx34 Ok so you need to send ipxe.efi to that target computer not undionly.kpxe. I’m suspecting that you have pfsense configured correctly and just misspoke about the boot file. Because undionly.kpxe should not boot (ever) on a uefi system yet you mentioned an ipxe error number.
I just downloaded ESXi 6.7. I’ll see if I can set it up during my lunch hour. I know I had 6.5 netbooting.

I am guessing the machine used the CSM module to boot BIOS instead of uefi when I was using undionly.kpxe, but even if I use ipxe.efi or ipxe.kpxe or ipxe.kkpxe in place of it I am still getting that same old error.
Sorry, I have the feeling it is going to be something basic I missed.
I have three option about what to send in the pfsense:
Default BIOS:
UEFI64:
UEFI32:
However the system only seems to react to the first default option, as when I leave that blank and put the corresponding option into the second and third options, I get nothing, it fails to pxe boot. -

ipxe.efi or ipxe.kpxe or ipxe.kkpxe
Despite the names those are binaries for different platforms. While the first one is for UEFI, the later two are for legacy BIOS!

@Sebastian-Roth
Thanks for clarifying that!
I also tried using a VM to boot with ESXI over PXE, but it didn’t change anything.
So I will now have my config like this?
Default: undionly.kpxe
uefi32: ipxe.efi
uefi64: ipxe.efiAt any rate; it is amazing how supportive you all are! Thanks.

@nexx34 I was able to boot a Dell laptop 7240 into the esxi 6.7 installer using my instructions tweaked for 6.7u2
-
I updated the install instructions to include ESXi 6.7u2. https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images/20
Make sure when you update the boot.cfg you remove the curly braces around the IP address of your fog server or NFS won’t work.
-
@george1421 I have removed the curly brackets, I only modified the boot.cfg in the /images/os/esxi/6.7u2/efi/boot/boot.cfg path, but I don’t think the other one matters since the only one being called is the one I modified. Thanks very much for the new instructions, maybe I just have to use tftp for this stuff.
By the way, you may have forgone replacing your IP with {fog-ip} in the section where you give the contents to be added to the “prefix=” line in the boot.cfg.Thanks for all your effort, I must be doing something dumb for it to not work, maybe there’s something with my computer I am using to test? It is pretty a old uefi…(though that shouldn’t be the catch).

Default: undionly.kpxe
uefi32: ipxe.efi
uefi64: ipxe.efiThere should also be
i386-efi/ipxe.efifor 32 bit UEFI machines. -
@Sebastian-Roth Thanks, then it’ll be:
Default: undionly.kpxe
uefi32: i386-efi/ipxe.efi
uefi64: ipxe.efi
The weird thing is, that with this even a VM that is set to uefi boot will not work.
It had 386MiB ram, was that too little?
In fact, my T420 that is confirmed to be uefi, will not boot PXE FOG when I set it to boot uefi exclusively.
I am pretty sure it is 64bit, but I can’t find for sure.
I’ll play around a bit with the entries in pfsense and report back in a bit. -
@nexx34 So just to confirm you followed my instructions exactly and didn’t deviate at all?’
Are you seeing the FOG iPXE menu at all when you boot the ipxe.efi?
-
@george1421 Nope, I followed them exactly, I think the problem really lies at the entries about undionly/ipxe.efi/etc in the pfsense dhcp settings, as when using legacy boot it works (but fails to load the esxi image, as that is efi) but that is just what I am guessing right now.
-
@nexx34 ok that is what I needed to know. If the esxi and fog setup is exact then lets focus on pfsense. Set all (2) non-i386 values to ipxe.efi. Yes I know this will break the bios boot systems, but for testing we need to understand if its an iPXE issue or a target system issues (note you might need to make sure the firmware is up to date on those lenovos, they have been known to have a very cruddy first gen bios/firmware)
-
@nexx34 Sorry for being a little bit spammy, for me the suspicion is mounting, that when I boot into fog, the client will not boot with uefi and instead takes the CSM regardless of the option being there in pfsense for the uefi files to load.
@george1421 Okay, I will do that, let us see if it will accept booting fog with uefi enabled and the undionly crutch removed >:)
-
@george1421 Yes, it tells me what it had already told be before when I tried this, “NBP is too big to fit in free base memory”.
I would take this is a client issue, but seeing how I had something along those lines in testing with a VM too, I really am clueless as to why it is happening…I mean, the machine I am testing now is halfway modern, it is a more recent lenovo. -
@nexx34 said in PXE Booting ESXI 6.7u2:
NBP is too big to fit in free base memory
ok that is the sign that the target computer is in bios mode or at least bios compatibility mode. I would grab a different model of target computer and try again. That way you can rule out the fog side and just focus on the target system.
-
@george1421 Okay, I will have to get such a PC real quick, looks like lenovo FW is shoddy all the way, because I was sure to enable the uefi option in the uefi menu.
-
@nexx34 @george1421 Well, I am testing a different computer now, it is a desktop this time, and it has gotten past the “Can’t get NBP” stage, what is making me wonder now is that afterfirst loading default.ipxe via tftp and the others (boot.php and bg.png) via http it all stops and nothing happens anymore, it just stays there.
-
@nexx34 Something isn’t right here.
The process is supposed to flow this way.
PXE rom requests dhcp boot options.
DHCP server gives {next-server} and {boot-file} setting to target computer.
Target computer downloads ipxe.efi
Target computer runs ipxe.efi (at this point you should see the ipxe.efi banner)
ipxe.efi chains to default.ipxe
default.ipxe then calls boot.php
boot.php should return the iPXE menu (you can view this menu by keying inhttp://<fog_server_ip>/fog/service/ipxe/boot.php?mac=00:00:00:00:00:00)
There is a line in the iPXE boot menu to load bg.png, but it has to have the iPXE menu to get that value.The just sits there part is confusing me. Lets have you post the iPXE menu using the path I provided. Lets see what it says. Post the results here in the thread.

Can you take a picture of the messages on screen and post here?
