8.4.1 - uefi vm issues - netboot not working

[itjamie]

Ive just experience this on a brand new build proxmox server with a new vm

i also could not get any vm to ipxe network boot when uefi was enabled + an efi drive attached (pre-enrolled keys unticked).

duplication steps.
proxmox repo: enterprise
- fully up to date proxmox 8.4.1
- create a new vm,
- set to efi boot, add an efi disk (i didnt pre-enroll keys),
- edit vm options. set boot option to net0, scsi0
- attempt to boot vm.

You will end up sitting at the bios without it ever even attempting to network boot.

removing the efi disk will allow it to attempt network booting

for ipxe you may have to add a rng device
