      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).
