This is only for deployments with DVS-backed networking with VMware Integrated OpenStack 7.x. It does not apply for integrations with NSX.
DHCP assignments will be failing. They may exist in OpenStack, but tenant instances will not receive IP address assignments in the guest operating system or vCenter.
We need to check several items that may be incorrect on the OpenStack side. We'll start with specific networks:
If anything from step #3 is missing the DHCP agent pod can be deleted. Upon re-creation all network namespaces will be re-created for networks scheduled to the VIO controller.
Once everything is validated OpenStack can safely be ruled out as the issue. The issue exists on the physical network outside of VIO.
