2.13. Example: Creating a Virtual Machine using Python
Virtual machine creation is performed in several steps. The first step, covered here, is to create the virtual machine object itself.
Example 2.12. Creating a virtual machine using Python
This Python example creates a virtual machine named
These options are combined into a virtual machine parameter object, before using the
vm1
. The virtual machine in this example:
- Must have 512 MB of memory, expressed in bytes.
vm_memory = 512 * 1024 * 1024
- Must be attached to the
Default
cluster, and therefore theDefault
data center.vm_cluster = api.clusters.get(name="Default")
- Must be based on the default
Blank
template.vm_template = api.templates.get(name="Blank")
- Must boot from the virtual hard disk drive.
vm_os = params.OperatingSystem(boot=[params.Boot(dev="hd")])
add
method of the vms
collection to create the virtual machine itself.
from ovirtsdk.api import API from ovirtsdk.xml import params try: api = API (url="https://HOST", username="USER@DOMAIN", password="PASS", ca_file="ca.crt") vm_name = "vm1" vm_memory = 512 * 1024 * 1024 vm_cluster = api.clusters.get(name="Default") vm_template = api.templates.get(name="Blank") vm_os = params.OperatingSystem(boot=[params.Boot(dev="hd")]) vm_params = params.VM(name=vm_name, memory=vm_memory, cluster=vm_cluster, template=vm_template, os=vm_os) try: api.vms.add(vm=vm_params) print "Virtual machine '%s' added." % vm_name except Exception as ex: print "Adding virtual machine '%s' failed: %s" % (vm_name, ex) api.disconnect() except Exception as ex: print "Unexpected error: %s" % ex
If the
add
request is successful then the script will output:
Virtual machine 'vm1' added.
