When yum command is executed on the virtual server created from the official template of RHEL, the following message is shown. "This system is not registered with an entitlement server. You can use subscription-manager to register."

Please ignore this message.

"This system is not registered with an entitlement server. You can use subscription-manager to register."

Enterprise Cloud 2.0 adopts RHUI instead of RHN for the authentication method of the virtual server (RHEL) created from the official image template.
* Yum and license authentication execution are provided through our repository server synchronized with RHN.

Since the license authentication using the subscription is not executed with the above authentication method, the above message will be displayed when using the yum command.
