Red Hat OpenStack

Red Hat OpenStack Notes

Overview

Fuel can deploy OpenStack using Red Hat OpenStack packages and Red Hat Enterprise Linux Server as a base operating system. Because Red Hat has exclusive distribution rights for its products, Fuel cannot be bundled with Red Hat OpenStack directly. To work around this issue, you can enter your Red Hat account credentials in order to download Red Hat OpenStack Platform. The necessary components will be prepared and loaded into Cobbler. There are two methods Fuel supports for obtaining Red Hat OpenStack packages:

  • RHSM (default)
  • RHN_Satellite

Red Hat OpenStack; Deployment Requirements

Deployment Requirements

Minimal Requirements

  • Red Hat account (https://access.redhat.com)
  • Red Hat OpenStack entitlement (one per node)
  • Internet access for Fuel Master name

Optional requirements

  • Red Hat Satellite Server
  • Configured Satellite activation key

Red Hat Subscription Management (RHSM)

Benefits

  • No need to handle large ISOs or physical media.
  • Register all your clients with just a single username and password.
  • Automatically register the necessary products required for installation and downloads a full cache.
  • Download only the latest packages.
  • Download only necessary packages.

Considerations

  • Must observe Red Hat licensing requirements after deployment
  • Package download time is dependent on network speed (20-60 minutes)

Red Hat RHN Satellite

Benefits

  • Faster download of Red Hat OpenStack packages
  • Register all your clients with an activation key
  • More granular control of package set for your installation
  • Registered OpenStack hosts don't need external network access
  • Easier to consume for large enterprise customers

Considerations

  • Red Hat RHN Satellite is a separate offering from Red Hat and requires dedicated hardware
  • Still requires Red Hat Subscription Manager and Internet access to download registration packages (just for Fuel Master host)

What you need

  • Red Hat account (https://access.redhat.com)
  • Red Hat OpenStack entitlement (one per host)
  • Internet access for Fuel master host
  • Red Hat Satellite Server
  • Configured Satellite activation key

Your RHN Satellite activation key must be configured the following channels

  • RHEL Server High Availability
  • RHEL Server Load Balancer
  • RHEL Server Optional
  • RHEL Server Resilient Storage
  • RHN Tools for RHEL
  • Red Hat OpenStack 3.0

Fuel looks for the following RHN Satellite channels.

  • rhel-x86_64-server-6
  • rhel-x86_64-server-6-ost-3
  • rhel-x86_64-server-ha-6
  • rhel-x86_64-server-lb-6
  • rhel-x86_64-server-rs-6

Note

If you create cloned channels, leave these channel strings intact.

Red Hat OpenStack; Troubleshooting

Troubleshooting

Issues downloading from Red Hat Subscription Manager

If you receive an error from Fuel UI regarding Red Hat OpenStack download issues, ensure that you have a valid subscription to the Red Hat OpenStack 3.0 product. This product is separate from standard Red Hat Enterprise Linux. You can check by going to https://access.redhat.com and checking Active Subscriptions. Contact your Red Hat sales representative to get the proper subscriptions associated with your account.

If you are still encountering issues, contact Mirantis Support.

Issues downloading from Red Hat RHN Satellite

If you receive an error from Fuel UI regarding Red Hat OpenStack download issues, ensure that you have all the necessary channels available on your RHN Satellite Server. The correct list is here <rhn_sat_channels>.

If you are missing these channels, please contact your Red Hat sales representative to get the proper subscriptions associated with your account.

RHN Satellite error: "rhel-x86_64-server-rs-6 not found"

This means your Red Hat Satellite Server has run out of available entitlements or your licenses have expired. Check your RHN Satellite to ensure there is at least one available entitlement for each of the required channels.

If any of these channels are missing or you need to make changes your account, please contact your Red Hat sales representative to get the proper subscriptions associated with your account.

Yum Error: Cannot retrieve repository metadata (repomd.xml) for repository: rhel-x86_64-server-6.

This can be caused by many problems. This could happen if your SSL certificate does not match the hostname of your RHN Satellite Server or if you configured Fuel to use an IP address during deployment. This is not recommended and you should use a fully qualified domain name for your RHN Satellite Server.

You may find solutions to your issues with repomd.xml at the Red Hat Knowledgebase or contact Red Hat Support..

GPG Key download failed. Looking for URL your-satellite-server/pub/RHN-ORG-TRUSTED-SSL-CERT

This issue has two known problems. If you are using VirtualBox, this may not be properly configured. Ensure that your upstream DNS resolver is correct in /etc/dnsmasq.upstream. This setting is configured during the bootstrap process, but it is not possible to validate resolution of internal DNS names at that time. Also, this may be caused by other DNS issues, local network, or incorrect spelling of the RHN Satellite Server. Check your local network and settings and try again.
