Boot New VM to ISO in XO-Lite?

[coolsport00]

Hi again great XCP-ng Team and Community!
I've yet another question with regards to functionality in XO-Lite. I just worked through my mess-up in creating a custom ISO SR on my XCP-ng Host so I can create a new VM from ISO. All good (now ). I boot up the VM and it never sees the ISO. There's no settings I can see to change boot order to boot the VM to ISO. I saw another Forums post:
https://xcp-ng.org/forum/topic/10760/starting-over-fresh-build-with-xo-lite./4
...and seems a way to get this to work is change the VM's boot firmware from UEFI to BIOS? Hmm.. ....not sure that's a good thing to do. If doing this works, can I change the firmware back to UEFI after creation? If this works, is this functionality going to be added for UEFI in a (hopefully soon) future XO-Lite version? Thanks!

Hi,

Can you describe all the steps in details so we can try to reproduce? Which template for example

[coolsport00]

@olivierlambert Nothing out of the ordinary Olivier. I created a VM in XO-Lite and selected my Ubunut ISO. I finished it and it powered on and would not boot to ISO. There is no setting, like in XO, to force boot the VM to the ISO....unless I'm missing something, which of course may be the case

[olivierlambert]

I need to know the exact template you selected

[coolsport00]

@olivierlambert Ah, ok; it was Ubuntu Jammy Jellyfish 22.04

[olivierlambert]

OK, in XO 5, when you create a VM from this template, do you need to change the boot order anywhere? Trying to understand exactly the difference and why it doesn't work out of the box in XO Lite

[coolsport00]

@olivierlambert There is nowhere in XO-Lite to be able to change the boot order. That is the issue. Lack of functionality for that.

[coolsport00]

@olivierlambert Greg, in my other forums post, confirmed this lack of functionality as well.

[coolsport00]

@olivierlambert - I just removed my UEFI-based VM and created BIOS-based one. It booted right up to the ISO. So it appears lack of functionality with UEFI booting to ISO. Not sure if that's a function of UEFI in general, or lack of feature set of XO-Lite. Well, may be both. Would be nice to have that boot order feature in XO-Lite, like in XO, which should take care of the issue with UEFI booting to ISO.

@olivierlambert
I can confirm that a new built debian VM in XO Lite with Debian Bookworm 12 template with UEFI boot will end up with this.

If I try to start it in XO5 it will have the same result
But if I change it to BIOS in XO5, it will start.

If I during the creation in XO-Lite change to BIOS it will start.

[olivierlambert]

Okay and what's the boot order by default of this template? When you create it in XO 5, same template, do you have the issue?

Default bootorder in 5 and Lite:

@ph7 We cannot see if they are all enabled in the screenshot. Also, I'm not sure to get it. With XO5 "end to end", does the VM boots?

[ph7]

@olivierlambert

Yes, They where all enabled but the clip was so wide I did cut it off.
The only thing I entered was the iso and changed to 2 cpu

New VM in xo5 with uefi

And starting fine in XO5

[olivierlambert]

So there's something different in VM creation between the two that makes UEFI boot not working

Thanks for the feedback, we'll try to reproduce internally and if confirmed, fixing it

[coolsport00]

@olivierlambert Thank you for looking into it Olivier; and...not that you all have extra time on your hands... ...but if you could enable being able to configure Host networking in XO-Lite, I think that would be a semi-urgent feature to release as well. Thanks.

@olivierlambert
When created with XO-Lite, secure boot is enabled but when created with XO5 secure boot is disabled.

XO-Lite:

XO 5

[coolsport00]

@ph7 where are you seeing secure boot in XO-Lite? I don't even have that option After creating a VM in XO-Lite, I see boot settings and Secure Boot is shown as Disabled

[ph7]

@coolsport00
I created the VM in Lite, then checked in XO5

[coolsport00]

@ph7 Ah, ok
