So what I did was fix the issue from the failed qubes startup

What do you means by that ?

I mean every step I did in the following post up to the “no bootable device”:

Create a Gaming HVM

In my case, the bios (Dasharo) doesn’t provide options to prioritize a GPU over another. So what I did was fix the issue from the failed qubes startup and switching to another TTY (Ctrl+Alt+F2). There was an annoying issue that kept switching back to TTY1 but that was fortunately solvable. To allow me to see the login screen it turns out that X11 crashing was the failure reason (I saw that on lightdm logs). Making dom0 Xorg work with an Nvidia Graphics Card I don’t understand why this is even…

Now I’m stuck with an issue where the HVM can’t boot if any PCI-e device is attached. I see some others are also encountering this. I documented this issue in this other thread:

• Can you check if there is any remaining custom code in xen.xml or stubdom (anything related to max-ram-below-4g) ?
• can you provide the logs file and your configuration, (and eventually the xen logs (sudo xl dmesg) when you start the HVM (add the grub parameter ‘loglvl=all’ and ‘guest_loglvl=all’ to the host before)
• can you provide the result of sudo dnf list | grep -E ^xen in dom0, and the result of sudo lspci -vvv -s YOUR_GPU in dom0

Sure! And thanks for the help, btw!

This time I started off with Qubes 4.2-rc3 and try the stubdomain patch (following this tip, which unfortunately didn’t work). If needed I can try some other time to do the full 4.2 fully updated (the testing xen version) and without the patch, but I have tried it before and the results where the same.

Here’s the high-level detail of what I did:

1. I installed Qubes 4.2 rc3 (without the graphics card)
2. added grub boot with my xorg.conf workaround to get Xserver to start
3. started Qubes with the graphics card attached (boots normally)
4. Applied your script here which as I understand applies only to qubes starting with gpu_.
5. Created a qube called gpu_manjaro and attached the graphics card (permissive=True and no-strict-reset=True)
6. boot from manjaro (arch linux) .ISO
7. then the error: “no bootable device”

Then I upgraded dom0 the the latest stable version and rebooted.

1. tried to start gpu_manjaro from manjaro ISO and again the same error: no bootable device

Lastly I tried the testing packages, which includes xen 4.17.2-8 6 which supposedly is patched. This is the version that I obtained the logs from.

1. renamed gpu_manjaro to manjaro so the patch wouldn’t apply.
2. tried to start manjaro from manjaro ISO and again the same error: no bootable device

The following are the logs with the loglvl=all and guest_loglvl=all (hopefully I applied it correctly).
