KVM api to run a virtual machine

I was wondering if there is a KVM API that allows you to start the KVM virtual machine using a simple command from a python script.

My Python script performs a series of checks to find out if we need to run a specific virtual machine, and I would like to start a virtual machine if I need to.

Now I need to find the API calls, but I cannot find a simple call to launch them on the libvirt website. Does anyone know if this is possible?

You can use the create () function from the python libvirt API bindings:

import libvirt

#connect to hypervisor running on localhost
conn = libvirt.open('qemu:///system')

dom0 = conn.lookupByName('my-vm-1')
dom0.create()

basically the python API is the C API called by libvirt.C_API_CALL minus the virConnect part or conn.C_API_CALL minus the virDomain part.

. API libvirt .

if you use a python script to control you KVM, I would suggest going through the following script. this will give you a good idea. http://russell.ballestrini.net/series/virt-back/
