I just installed upgrades via apt full-upgrade and rebooted afterwards.

Now i've got the problem that 3 vm's that are based of a template wont boot anymore.


Even if i clone the template into a new vm and start it i get the same problem.


"BdsDxe: failed to load Boot0001 ..."

The disks seem totally fine to me, i can mount them and browse the content, boot partition with EFI and root are there and look fine.

Same problem here! VMs with OVMF (UEFI) won't boot anymore! No problems with Default (SeaBIOS) VM though!

OK, got my VM running again with the hint from @onepamopa in this thread to switch to machine type pc-q35-3.1.

I edited my configuration /etc/pve/qemu-server/110.conf and replaced the line
machine: q35
with
machine: pc-q35-3.1
and the VM booted just fine!

The list of supported machine types:

My rollback went smooth, i just upgraded again to test your fix thanks for the details.

And it works. I tested some more and which is really interesting:

Setting "machine: q35" doesnt work, but "pc-q35-4.1" works !
But "q35" is linked to "pc-q35-4.1", so they should be the same ??

very strange indeed.. if you can easily reproduce it by setting/unsetting 'machine', it would help if you could post 'qm showcmd XXX' output with 'q35' and 'pc-q35-4.1' set as machine type!

The first difference only the parameters are sorted differently.
In the second difference there is however an additional size=131072 parameter. And the 131072 Bytes do not match the EFI-disk size with 1 MB!
And machine tpye as well as pve0 vs. pve2 in the last difference. Whatever those pveX-parameters do.

so after some further analysis this seems to be fallout from a bug fix for an issue affecting efidisks on some storages. unfortunately the fix could not be made backwards compatible for all cases - to fully fix your VMs, you need to re-write your EFI entries or re-install your bootloader after booting with the plain 'q35' machine type (e.g., using the EFI shell, or a live-CD of your choice).

So, a guide for this is available somewhere?

so after some further analysis this seems to be fallout from a bug fix for an issue affecting efidisks on some storages. unfortunately the fix could not be made backwards compatible for all cases - to fully fix your VMs, you need to re-write your EFI entries or re-install your bootloader after booting with the plain 'q35' machine type (e.g., using the EFI shell, or a live-CD of your choice).

Can't we just leave it as it is ? Or will pc-q35-4.1 be upgraded to pc-q35-4.1+pve2 including the fix as well ?

you can leave it as is, but won't get any changes from future machine type updates, or fixes that are incompatible with 4.1 machines and version guarded (like the current one). the original issue was that with the EFI disk on some storages, EFI settings were not persisted correctly because of a mismatch of EFI disk size. changing the machine type to -4.1 will revert to the old, broken behaviour. unfortunately it was not possible to fix this in a compatible way, so you need to either re-initialize the EFI disk with the new machine type, or fix the affected VM to the old, buggy machine type.

What i don't understand is, why does it work with pc-q35-4.1 but not with q35, when the later is only an alias for ther first?
Code:
q35                  Standard PC (Q35 + ICH9, 2009) (alias of pc-q35-4.1)

because q35 gets an implicit pve-specific suffix +pve2 (the newest, since q35 is not version specific), but pc-q35-4.1 gets +pve0 (the oldest, since it's version-locked). the check whether to use the new or old behaviour is guarded by >= 4.1+pve2

Alright good to know, i will reinstall the efi bootloader later this month.

Can someone tell me how to "reinstall the efi bootloader" for the affected VMs ?

that depends on your guest OS. for example, most Linux distributions have it as an option in their installer's rescue mode, or you could boot with a live CD and use that.
