@rodluz I tried a manual installation of the updated init.xz as outlined in your instructions, and there was no change. I also upgraded my FOG server and reinstalled your experimental XCP bzImage from earlier in this thread but did not see any change in VM behavior after doing so.

Out of curiosity, @BPSTravis, what hardware are you running XCP-ng on? I know it’s virtualized, but maybe there’s some CPU feature I have disabled in BIOS on my XCP hosts or something like that?

Also, thanks for your patience. I’m only available to work on this once or twice in the middle of the week as I’m part-time with this organization.

@Tom-Elliott I must’ve propagated the pool certificates to the VM already. I looked at my cloned VM and that prompts to propagate certificates. On the clone I matched the settings you called out (Video RAM, CPU, and RAM) and nothing changed.

@Tom-Elliott @BPSTravis Not much to hide, see attached screenshots as I couldn’t find a way to export the config as an XML. I removed the MAC address from the network screenshot, and note the disk shows disconnected because the VM was shutdown while taking screenshots. Disk resides on an NFS share alongside my other VMs.

The only difference between this VM and the clone I made was removing the VTPM on the clone.

@Tom-Elliott Just checked, no kernel args set at either host or global levels.

As for your theory about video output going somewhere else, I’m struggling to think of a way to test it as this instance is a virtual machine with no physical display outputs. I did toggle off the VGA setting in the VM advanced settings in XCP, which didn’t make a difference. Once the VM reached the point where it hangs (or appears to), I switched that setting back on, and off, and back on, hoping for a change but nothing happened.

I’ve got the VM set in a capture task now that I’ve manually registered it, and the task never fires according to my FOG web GUI, which makes me think the VM is actually hanging instead of just redirecting display output somewhere else. I tried forcing the task to start, and nothing changed.

@Tom-Elliott As I couldn’t find a way to disable the TPM without deleting it, I cloned the VM just in case removing the TPM screwed up my Windows install, and added the clone to FOG with the same settings as the original (rodluz’s experimental kernel, same image associated, no kernel arguments, etc).

The cloned VM still hangs at EFI stub: Measured initrd data into PCR 9.

@rodluz Thanks for the detailed instructions - that was quite helpful in getting your kernel installed and set up.

Unfortunately it didn’t work for me. I got stuck at the same point. Screenshot attached. I also tried adding the host kernel arguments back with the experimental kernel and that didn’t change it either. Anything else I should try?

@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.

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!
