First reboot ends in UEFI Shell about ubuntu-server-zfsbootmenu

[Sithuk]

Hi ravenclaw,

The script variables you posted look ok. I'm not familiar with kvm unfortunately, so can't be much help with its setup.

Please could you provide the script installation log? It should be in the /var/log directory of the new installation. Before the first reboot, that would be in the mountpoint where the new installation is created (/mnt/ub_server).

The log would let me check whether anything went wrong during the installation.

To get it this far with kvm, I had to manually add a serial number to each virtual disk in xml, so your script is able to find them under /dev/disk/by-id. But I don't think that this has something to do with the shell issue. solution

This time I bootet ubuntu 22.04 in EN (instead of DE), checked out current version, and started the initial run. No changes at all. Selected the first disk.
After reboot i get this:

Here is the log from this run:
ubuntu_setup_zfs_root.log

Thank you for your time.

I can't see anything obviously wrong in the log. Are you able to manually select the efi file to boot from?

Yesterday I tried installing in VirtualBox, and it worked flawless (only tested if it could boot, not further).
The only difference I could spot was sda(virtualBox) vs vda(kvm).
So I tried kvm with a sata disk instead of a virtio disk, but this did not work.

This is my first encounter with the uefi shell, could you give me a hint/link on how to boot the efi file?

I’m glad the script worked in Virtualbox. Hopefully you can test on your hardware server when it arrives too.

For your kvm issue, are you able to select the efi file from a boot menu as part of the kvm boot sequence? Virtualbox has an option to press F12 during boot to select boot device. Does kvm have something similar?

Using from your link I tried all boot options (Sata disk, virtio disk), but only the integrated shell booted.

I found the rEFInd bootloader

and the zfsbootmenu initrramfs with the refind_linux.conf, this looks ok to me (to an uefi/zfs/zfsbootmenu noob)

At first, starting refind_x64.efi resulted in a permission denied msg that told me this is not a secure boot signed efi file.
So after choosing a efi bios without secureboot for kvm, (the one I chose earlier linked to a secboot one: OVMF_CODE_4M.ms.fd -> OVMF_CODE_4M.secboot.fd)
I could execute the refind_x64.efi, but it seems there is something missing (maybe it does not find the config file).

I did a fresh initial install with the secureboot disabled firmware, but all I got again was the uefi shell.

Seems refind crashes freeing the banner image. link

Adding hideui banner to refind.conf solved the problem.

At line 757 of your script I simply added:

echo hideui banner >>/boot/efi/EFI/refind/refind.conf

But I still have to manually boot it via efi shell.

That's good news. I'm glad you finally got the script to work with kvm. Thank you for posting the solution. If you find the solution to having to manually boot the kvm VM each time, please post that here too.
