Jira issue: CRDB-66511

Start with pkg/cmd/roachtest/README.md and the failure path at test_runner.go:1364. Review the linked TeamCity log and artifacts for the IBM br-sao instance-creation failure, then use the roachdash entry to compare related cluster_creation failures. Done means the cause is addressed and the IBM cluster_creation test can create stable instances successfully.
