Oh, did you pass the list of sub-modules to it when running
eg, ./scripts/git-submodule.sh update ui/keycodemapdb
the list of submodules you need is printed in the configure output summary.

This shouldn't have happened in your case though, if you have already run
'git-submodule.sh update ...list of modules...' on the host machine, with
the same list of modules that the guest 'configure' printed out.
