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_pci.dts

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
