If you have a template with all the characteristics you need, you can
easily create the 100 VMs with a Python script like this:

#!/usr/bin/python

import ovirtsdk.api
import ovirtsdk.xml

# Connect to the server:
api = ovirtsdk.api.API(
    url="https://rhel.example.com/ovirt-engine/api",
    username="admin at internal",
    password="******",
    insecure=True,
    debug=False,
)

# Locate the cluster:
cluster = api.clusters.get(name="mycluster")
cluster = ovirtsdk.xml.params.Cluster(id=cluster.get_id())

# Locate the template:
template = api.templates.get(name="mytemplate")
template = ovirtsdk.xml.params.Template(id=template.get_id())

# Create the VMs:

for i in range(0, 99):
    name = "vm%d" % i
    print("Creating VM %s ..." % name)
    vm = ovirtsdk.xml.params.VM(name=name, cluster=cluster,
template=template)
    api.vms.add(vm)

# Disconnect:
api.disconnect()
