EFI Stub Errors on XCP-ng Virtual Machine Attempting 'Perform Full Host Registration and Inventory'

[JCS-RVK]

Hello!
I’m trying to capture a Windows 11 base image from an XCP-ng VM. The VM will boot to the FOG menu, and I can select the desired option (Full host registration), but after loading bzImage and init.xz, the VM hangs on

EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
EFI stub: Measured initrd data into PCR 9

I’ve tried a list of different kernel versions:

• 5.15.93
• 5.15.98
• 6.1.22
• 6.1.89
• 6.6.49
• 6.6.69
• 6.12.25
• 6.12.35
• The experimental kernel listed here: https://github.com/FOGProject/fos/issues/108

None have allowed the VM to get any further. What else should I be trying?

Other devices are able to image successfully. We deploy laptops to staff and students, and all are imaging as expected.

System info:
FOG server is running AlmaLinux 9.5, in a VM that was migrated from ESXi to XCP-ng.
FOG version is 1.5.10.15
XCP-ng hosts are Dell PowerEdge R630. 2x Intel Xeon E5-2660v3, 128GB RAM
Windows 11 VM has 2 CPUs, 4GB RAM, 64GB disk

Thanks for your time!
