<![CDATA[Boot New VM to ISO in XO-Lite?]]>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!

Yes, I can confirm if I disable the Secure boot option the VM will start.
After a quick flash of the pxe boot screen, the Debian installer will appear, and I can continue the installation.

I spotted a small bug in the XO-Lite system page: Secure boot was always showing Disabled I'll fix this issue soon.

According to my tests, your VM isn't booting because Secure Boot is enabled, but your pool isn't configured for it.
If I remember correctly, in XO 5, Secure Boot is disabled by default, but in XOLite, if your template sets "platform.secureboot" to true or auto, the VM will be created with Secure Boot enabled.
Can you confirm that if you disable Secure Boot on your VM, it boots correctly?

ping @lsouai-vates to plane the possibility to enable/disable secure boot in the XOLite/XO6 UI, and possibly transform auto to false if the pool isn't compatible. Or at least, as in XO 5, warn the user

@coolsport00
Here is a hint in xo 5 when the newly created vm is running.

To be precise, The non working VM created in XO-Lite is not running, it is when it get stuck while trying to boot.

It is the same pool.

I created the VM in Lite, then checked in XO5

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

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

Thanks.

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

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

Also, I'm not sure to get it. With XO5 "end to end", does the VM boots?

(Fully updated xcp and xo ce 4dfd4)
Default bootorder in 5 and Lite:

When you create it in XO 5, same template, do you have the issue?

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.

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.

That is the issue. Lack of functionality for that.

Trying to understand exactly the difference and why it doesn't work out of the box in XO Lite
