[SOLVED] Proxmox VE arm64 (on x64) - cannot add EFI disk "Can't use an undefined value as an ARRAY reference"

[Chris7Lives]

Hi!
I have Debian Arm64 installed on ProxmoxVE. My ProxmoxVE runs on x64 and debian VM runs with arm64 emulation.
I have following VM settings:

agent: 1
arch: aarch64
bios: ovmf
boot: order=scsi1;scsi0
cores: 2
memory: 8192
meta: creation-qemu=7.1.0,ctime=1673882121
name: DebianArm64
net0: virtio=de:ad:be:ef:02:20,bridge=vmbr0,firewall=1
numa: 0
ostype: l26
parent: Start
scsi0: local-lvm:vm-220-disk-0,discard=on,size=16G,ssd=1
scsi1: none,media=cdrom
scsihw: virtio-scsi-pci
smbios1: uuid=2a113c33-f0dd-44a8-ab89-c154aeeee48c
sockets: 4
tpmstate0: local-lvm:vm-220-disk-1,size=4M,version=v2.0
vga: virtio,memory=512

Now the problem is, if i would like to add EFI disk (so that EFI variables are retained, for setting automatic boot), then getting following error:
"Can't use an undefined value as an ARRAY reference at /usr/share/perl5/PVE/QemuServer.pm line 3374. (500)"

The error happens every time.

How do you add this EFI disk? Through the GUI?

Edit: I get the same error when using your config

 

[Matthias.]

Okay, so with aarch64, you can't use the default EFI version.
efitype=2m is the only type that works.
E.g. qm set VMID -efidisk0 local:1,efitype=2m,pre-enrolled-keys=1,format=qcow2 (adapt storage and format as needed)

Dear Matthias,
Works like charm!
Can this be added into GUI as well?
Kind regards,
Chris

Great!
Please mark this thread as solved, so others with the same issue find it more easily (click edit, there's a dropdown near the title)

Can this be added into GUI as well?

Sure, I just sent a patch to the list : )
