When deploying VMware Cloud Foundation (VCF) 9.1, the deployment task fails during the "Deploy and configure VCF Management Platform" step with the subtask "Monitor VCF Management Services Deployment Task" and error "Failed to bootstrap VCF services runtime":
Reviewing the domainmanager.log on the SDDC Manager appliance reveals the following error:

VMware Cloud Foundation 9.1
In complex or resource-constrained environments, the VCF Management Services (VMSP) bootstrap VM may require more time than the default setting to complete its initialization and runtime setup. If the SDDC Manager cannot successfully reach the Health API within the allocated window, it marks the bootstrap task as failed.
If networking and firewall rules (specifically bi-directional connectivity on port 5480) have been verified and the task continues to time out, increase the deployment timeout values on the SDDC Manager appliance.
Please ensure to take a snapshot of the SDDC Manager appliance before proceding!
