Installing Libvirt on Ubuntu for Python is as easy as:

sudo apt install -y python python-pip libvirt-dev
pip install libvirt-python

 

With the default installation, you could miss some of the Libvirt API bindings exposed to the Python package, although you have the latest version.  So if you ever need to compile the library yourself, here you go (my setup was Libvirt 4.0.0 on Ubuntu 16.04 with Python 2.7):

#!/usr/bin/env bash

WORK_DIR="/tmp/libvirt"

sudo apt update
sudo apt install -y git

# LIBVIRT

WORK_DIR_LIBVIRT="$WORK_DIR/libvirt"
mkdir -p $WORK_DIR_LIBVIRT
cd $WORK_DIR_LIBVIRT

LIBVIRT_VERSION="v4.0.0"
git clone -b $LIBVIRT_VERSION --single-branch --depth 1 https://github.com/libvirt/libvirt.git .
git checkout $LIBVIRT_VERSION

sudo apt install -y \
	gettext \
	libtool \
	autoconf \
	autopoint \
	pkg-config \
	xsltproc \
	libxml2-utils
./bootstrap

sudo apt install -y \
	libnl-3-dev \
	libnl-route-3-dev \
	libxml2-dev \
	libdevmapper-dev \
	libpciaccess-dev \
	python
./configure

sudo apt install -y intltool
aclocal

make
sudo make install


# LIBVIRT PYTHON

WORK_DIR_LIBVIRT_PYTHON="$WORK_DIR/python"
mkdir -p $WORK_DIR_LIBVIRT_PYTHON
cd $WORK_DIR_LIBVIRT_PYTHON

LIBVIRT_PYTHON_VERSION="v4.0.0"
git clone -b $LIBVIRT_PYTHON_VERSION --single-branch --depth 1 https://github.com/libvirt/libvirt-python .
git checkout $LIBVIRT_PYTHON_VERSION

sudo apt install -y python-dev

python setup.py build
python setup.py install


# CLEANUP

rm -r $WORK_DIR
sudo apt purge -y \
	gettext \
	libtool \
	autoconf \
	autopoint \
	pkg-config \
	xsltproc \
	libxml2-utils \
	libnl-3-dev \
	libnl-route-3-dev \
	libxml2-dev \
	libdevmapper-dev \
	libpciaccess-dev \
	intltool \
	python-dev

The above may vary depending on your Ubuntu setup. Just pay attention to errors regarding missing tools.

Now check for the symbols you needed:

sudo apt install -y binutils
nm -g /usr/local/lib/libvirt.so

 

I recommend compilation attempts inside an isolated environment.
