New boot entry on UEFI is lost unless existing ones are removed

[kpldvnpne]

BEFORE SUBMITTING YOUR ISSUE, PLEASE LOOK AT THE PINNED ISSUES AND USE THE SEARCH FUNCTION TO MAKE SURE IT IS NOT ALREADY REPORTED. ALWAYS COMMENT ON AN EXISTING ISSUE INSTEAD OF MAKING A NEW ONE.

Describe the issue
I have installed multiple Linux distros (ArchLinux, VoidLinux, etc) inside UTM VMs and after adding the EFI entry and ensuring that there is a EFI boot entry using efibootmgr, the system forgets the boot entry, no matter how many times I do this process. However, once I remove one existing boot entry, then the system stops forgetting the newly added EFI entry.

I don't know if this issue is specific to UTM, but given that this issue does not occur on Physical Machines (which I checked multiple times), I believe it is related to at least a component inside UTM. My best guess is that the VM that UTM configures for us inside QEMU has a hard limit of how many boot entry the firmware can handle.

If you need any information from me, I would be happy to provide.

Configuration

• UTM Version:
• macOS Version:
• Mac Chip (Intel, M1, ...):

Crash log
Not Applicable.

Debug log
I don't have Debug Log now because I have fixed the issue but if the above description is not sufficient to recreate this issue, I can do everything so that relevant Debug Log is created.

Upload VM
The issue is not related to a specific VM. However, if you need it, here it is:
