       error: vmTools: the `kernel` argument (kernel-modules) has no
       `target` attribute, so the kernel image filename cannot be determined.

       If you are passing a module tree (e.g. from `pkgs.aggregateModules`) to
       make extra modules available, pass it via `kernelModules` instead and
       keep `kernel` pointing at a real kernel derivation. Alternatively, pass
       `kernelImage` explicitly with the path of the bootable image relative
       to the `kernel` derivation output (e.g. "bzImage" or "Image").
