Looking at the domain manager logs on the VCF Installer show:
Bootstrap failed during stage 'DEPLOY0001 - Preparing VCF services runtime cluster': Command or operation failed with exit code 1. Please retry the operation or contact support if the issue persists. [VCFMS-BOOTSTRAP-999]"

Environment

VCF 9.1

Cause

By default, the following internal CIDR: 198.18.0.0/15 used by VCF services runtime. If the environment uses an overlapping CIDR range, it can lead to connectivity issues during the deployment and result this failure.

Resolution

1. To resolve this issue,download the deployment json from the VCF Installer, find the internalClusterCidrIpv4 entry similar to:
   "internalClusterCidrIpv4": "198.18.0.0/15" 
   
   
2. Change the CIDR to one of the following instead:
   240.0.0.0/15
   250.0.0.0/15
   
   
3. Save the Json and upload it to the VCF Installer. 
4. A new deployment will need to be started using this Deployment JSON, please ensure the ESX hosts are re-installed.
