Why overcloud nodes fail to get DHCP IP from undercloud node during deployment?

Solution Verified - Updated -

Issue

  • When the undercloud is a virtual machine running on VMware ESXi, DHCP during Introspection is successful, but it fails during deployment. DHCP requests are being received on the tap device, but the offers are not received by the nodes.
  • a virtualized Director on VMware causes overcloud deploy to fail.
