Description of problem:

Machine CIDR is an optional item in creation, however, if users use the existing VPC, the CIDR should match with the VPC’s setting. We’d better move the Machine CIDR into required once the user uses the existing VPC and notify the user to check the settings between VPC and machine CIDR.

Version-Release number of selected component (if applicable):

prod

How reproducible:

always

Steps to Reproduce:

1. Select the CCS infrastructure, and fulfill the required attribute in OSD creation wizard then go to the ‘Networking’ > ‘Configuration’ page
2. Select the “Install into an existing VPC” checkbox
3. Fulfill the VPC settings
4. Go to next page to check the machine CIDR

Actual results:

Machine CIDR is an optional item

Expected results:

We’d better move the Machine CIDR into required once the user uses the existing VPC and notify the user to check the settings between VPC and machine CIDR.
