In this post I will share how to manage virtual machine with libvirt with python programming language. I will give an example how to connect to the hypervisor, and also listing the virtual machines on the local or remote hypervisor node.

Requirements
First we need to install the requirements, libvirt-bin can installed on local or remote node. Such as :
• python3
• pip3
• ibvirt-python
• ibvirt-dev
• libvirt-bin (installed on hypervisor node)
Setup
Environment that I use for this example is using ubuntu as the hypervisor node and also for the libvirt client.
Install depedencies
sudo apt update
sudo apt -y install python3 python3-pip libvirt-dev libvirt-bin
pip3 install libvirt-python
Connect to hypervisor
vi connect-libvirt.py
import libvirt
LIBVIRT_USERNAME = "iputra"
LIBVIRT_HOST = "localhost"
# LIBVIRT_URI = "qemu+ssh://%s@%s/system" % (LIBVIRT_USERNAME, LIBVIRT_HOST)
LIBVIRT_URI = "qemu:///system"
try:
conn = libvirt.open(LIBVIRT_URI)
except libvirt.libvirtError:
print('Failed to open connection to the hypervisor')
sys.exit(1)
print(conn.listAllDomains(0))
