Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: No option to customize the worker/masters machine specifications Consequence: Users had to customize the RHV/oVirt template prior to installation, and point the installer to that template using an environment variable Fix: Allow customization of workers/masters by implementing MachinePool for this platform, and exposing it in the install-config.yaml Result: masters/workers VM instances are created according to the MachinePool details, including cpu/mem/disk/vmType/instanceType. As a result of now knowing how to handle a different disk size, the default disk size now is 120GB.

Verified on:
openshift-install-linux-4.4.0-0.nightly-2020-05-24-133612

Steps:
1. created a config file: # openshift-install create --dir install_files/ install_config
2. edited the install-config.yaml setting the following variables with non-default value (XX)
(...)
controlPlane/compute:
  name: master/worker
  platform:
    ovirt:
      cpu:
        cores: XX
        sockets: XX
      memoryMB: XX
      osDisk:
        sizeGB: XX
      vmType: high_performance
(...)
platform:
  ovirt:
    api_vip: <ip>
    dns_vip: <ip>
    ingress_vip: <ip>
    ovirt_cluster_id: <id>
    ovirt_storage_domain_id: <id>
    ovirt_network_name: ovirtmgmt
    vnicProfileID: <id>
(...)

3. # openshift-install create --dir install_files/ cluster
4. on UI, checked the created machines properties

Results:
installation successfully finished and non-default properties set on yaml file present on vms

Do we then plan instead to document customizing install-config.yaml. 
Please forgive my ignorance, but I couldn't find and bz reflecting to get this into the docs and I would highly appreciate any hint to it.
