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!

I have a windows 11 golden VM residing on an xcp-ng 8.3 host, I am able to boot into the fog menus and upload images(although sometimes the console window blanks out after 3-4 minutes so I use snapshots and brute force to get it to complete).

Try adding this to your host kernel arguments: xen_emul_unplug=unmodified nomodeset vga=788

Also use the intel nic option not realtek. I am not using a custom kernel for my VM, just the latest same as any other machine.

UEFI bios mode on the VM(required for TPM).

@BPSTravis
Sorry for the slow response. Apparently I didn’t have email alerts set up yet, and I’m only at this job in the middle of the week, so just seeing your reply this morning.

I manually added the host and tried the host kernel arguments you suggested. This did not make a difference. I also tried with just xen_emul_umplug=unmodified and this did not work either.

I switched to the Intel NIC option, this did not make a difference.

UEFI BIOS mode was set already.
