Hi, I have a virtualenv which I am using for production (I need python 2.7 and certain libraries which can not be easily installed on the host environment). Now I am trying to install also libvirt, but I have not succeeded yet. The problem that I have now looks quite difficult to solve. This is the script I am using to install libvirt (bash script): install_libvirt_ ( ) {     local myvirtualenv="$1"     local libvirt_tag=v0.9.9     cd $TMP_DIR     git clone git://libvirt.org/libvirt.git     cd libvirt     git checkout $libvirt_tag     mkdir -p $VIRTUALENVS_DIR/$myvirtualenv/usr     sudo apt-get install autopoint     # configure: error: You must install the GnuTLS library in order to compile and run libvirt     sudo apt-get install -y gnutls-bin gnutls-dev     # configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt     sudo apt-get install -y libdevmapper-dev libdevmapper     # configure: error: You must install python-devel to build Python bindings     sudo apt-get install -y python-all-dev     ./autogen.sh --prefix=$VIRTUALENVS_DIR/$myvirtualenv/usr --enable-compile-warnings=error     make     make install } But this is failing with error message: checking for python script directory... ${prefix}/lib/python2.7/site-packages checking for python extension module directory... ${exec_prefix}/lib/python2.7/site-packages configure: error: You must install python-devel to build Python bindings python-devel does not exist. I have used python-all-dev, but it has not solved the problem. Has somebody succeeded in installing libvirt-python inside a virtualenv? Thanks, Daniel Gonzalez
