I upgraded L4 version to 24.08 instead of 23.10 because 24.08 contains the missing virt-arm_virt-64_pci.dts file. I'm building for arm64 and when I run the demo VM-basic-pci, I got the following error ! I didn't change anything in the dts/dtb or ned scripts excepting the typo of
overlay = "-drom/virt-pci.dtbo"
What is the problem here ?

Hi Mohamed,
can you please check your arm64 build tree and look into the folder 'assets/dtb/'? There should be links to all the .dtb files of uvmm. The link of the file in question on my machine is:
[...]/.build-arm64/pkg/uvmm/configs/dts/OBJ-arm64_armv8a-std-l4f/virt-arm_virt-64_pci.dtb
If the file is missing in the linked folder, please check the corresponding source directory:
<src>/pkg/uvmm/configs/dts/
If virt-arm_virt-64_pci.dts isn't in there, you can download it from our development version of L4Re on github and recompile the uvmm package.
https://github.com/kernkonzept/uvmm/blob/master/configs/dts/virt-arm_virt-64...
If the file is there, please check that '<arm64-build>/assets' directory is in your MODULE_SEARCH_PATH.
Let me know, if this solves the missing file problem.
Cheers, Philipp

Thanks Matthias I'm going to fix the typo of *virt-pci.dtbo*. What about the missing file *dtb/virt-arm_virt-64_pci.dtb *?
