What happened?
When starting the guest, specifically after the selection has been made on the GRUB screen, there is a brief warning as follows:
EFI stub: WARNING: Failed to measure data for event 1: 0x800000000000000b
From what I have been told, this means that the UEFI firmware's memory buffer allocated for recording the human-readable TCG Event Log ran out of space.
The solution (I believe) is to increase the hard-coded memory buffer for the TCG event log when assigning a virtual TPM 2 to the guest. The user (me) has no control over the size.
Log file:
VBox.log
How can we reproduce this?
The guest is a fairly standard installation of Ubuntu 26.04, installed without the TPM-backed FDE method. Subsequently, Clevis was installed.
I suspect that the addition of Clevis increased the memory requirements, because it increases the size of /boot/initrd.img and the number of event log entries. This might be what triggers the EFI_VOLUME_FULL message.
Did you upload all of your necessary log files, screenshots, etc.?
