https://access.redhat.com/documentation/en/red-hat-cloudforms/4.1/paged/installing-red-hat-cloudforms-on-red-hat-enterprise-linux-openstack-platform/

Section Number and Name: 

Describe the issue: 

When installing CloudForms appliances into OpenStack, if you do not use DHCP on the appliances it is necessary to set the MTU of the appliance interface(s) to 1400 in the ifcfg-eth* file(s).  If not set correctly provider communication problems will present intermittently and the problem is fairly difficult to determine based on logs etc.

It might also be appropriate to address installing with provider networks and not needing a public floating IP.

Suggestions for improvement: 

Add a section to the documentation for Installing Red Hat CloudForms on Red Hat Enterprise Linux OpenStack Platform to inform users of this requirement.

Additional information: 

I have seen accounts of this issue a minimum of 3 times this month, I suspect a fourth but its as of yet unconfirmed.

Thank you for raising this bug.

We have evaluated this request, and while we recognize that it is a valid request for the documentation, we do not expect this to be implemented in the product in the foreseeable future. We are therefore closing this out as WONTFIX. 

If you have any concerns about this, please feel free to contact Andrew Dahms.
