Auto Boot Timeout

what exactly do you mean? do you mean the efi timeout before loading the bootloader (like grub?)
 
Yes,
Code:
efibootmgr -v
BootCurrent: 0004
Timeout: 3 seconds
BootOrder: 0004,0001,0002,0000
Boot0000* UiApp    FvVol(7cb8bdc9-f8eb-4f34-aaea-3ee4af6516a1)/FvFile(462caa21-7614-4503-836e-8ab6f4662331)
Boot0001* UEFI QEMU QEMU HARDDISK     PciRoot(0x0)/Pci(0x1e,0x0)/Pci(0x1,0x0)/Pci(0x5,0x0)/SCSI(0,0)N.....YM....R,Y.

So the problem it seems, its the efidisk not storing the timeout setting.
I wonder how proxmox saves uefi boot options in efidisk.
Maybe when the vm is on, proxmox overwrite the timeout var.
