   builds our specifically configured linux image.
   
   With `runqemu qemux86-64 core-image-bmw` the linux image runs within a virtual machine.
-  
   We assume that this is running on and compiled for an x86-64 architecture. For other architectures, some settings must be adjusted.
+  
+  Unpack ros_server.tar.gz somewhere, adjust pathes in fuerte-ros-base.rosinstall to the location where it has been unpacked.
+  After starting the virtual machine, copy the installation script from the guest system to the home directory with scp and execute it.
+  
+    scp lukas@192.168.7.1:/<location of repository>/install.sh .

 RESOLVED ISSUES:
   - recipes for python-pyyaml and python-rospkg create invalid shell scripts (header line refers to python-native instead of python.)
     RESOLVED by patching distutils class--will be committed to yocto.
 
 OPEN ISSUES:
-  - Yocto: python-setuptools requires python-modules at run-time.
+  - recipe for log4cxx requires another patch.
+  - Yocto: python-setuptools requires some python-modules at run-time.
+    TEMPORARILY RESOLVED by adding all python-modules in the image
+    SHOULD BE RESOLVED by creating an appropriate patch for python-setuptools and contributing to openembedded-core
   - rospkg modules are not found when runnning python.
+    UNCLEAR. Maybe we need rospkg-dev?
+  - Compilation with make fails in the virtual machine because of insufficient memory during compilation.
