The installer for IBM Cloud currently only checks the first group of subnets (50) when searching for Subnet details by name. It should provide pagination support to search all subnets.

    4.17

    100%, dependent on order of subnets returned by IBM Cloud API's however

    1. Create 50+ IBM Cloud VPC Subnets
    2. Use Bring Your Own Network (BYON) configuration (with Subnet names for CP and/or Compute) in install-config.yaml
    3. Attempt to create manifests (openshift-install create manifests)
