Product notes, new features, and known bugs for Red Hat Satellite.
Chapter 1. Introduction
Red Hat Satellite is a system management solution that enables you to deploy, configure, and maintain your systems across physical, virtual, and cloud environments. Satellite provides provisioning, remote management and monitoring of multiple Red Hat Enterprise Linux deployments with a single, centralized tool.
Red Hat Satellite Server synchronizes the content from Red Hat Customer Portal and other sources, and provides functionality including fine-grained life cycle management, user and group role-based access control, integrated subscription management, as well as advanced GUI, CLI, or API access.
Red Hat Satellite Capsule Server mirrors content from Red Hat Satellite Server to facilitate content federation across various geographical locations. Host systems can pull content and configuration from the Capsule Server in their location and not from the central Satellite Server. The Capsule Server also provides localized services such as Puppet Master, DHCP, DNS, or TFTP. Capsule Servers assist you in scaling Red Hat Satellite as the number of managed systems increases in your environment.

3.4. Known Issues
These known issues exist in Red Hat Satellite 6 at this time.
If you export a Content View with contents that require a large amount of disk space, you might see the
Timed out reading data from servererror message. Until Red Hat Bug 1668544 is resolved, use the Knowledgebase solution How to setup hammer API request timeout on Satellite 6 to fix this issue.
- If you have SELinux enabled, using Kerberos (KRB) keys instead of RSA keys can cause remote execution jobs to fail.
- Satellite 6.5-beta does not support UEFI HTTP boot provisioning. The work on this feature is in progress in the upstream, therefore, you might see the templates for this feature. Do no use this feature until it is supported.
If you run Ansible jobs on Red Hat Enterprise Linux 8 hosts, you must set the
ansible_python_interpreterparameter for the Red Hat Enterprise Linux 8 operating system to point to
/usr/libexec/platform-python. For more information, see the Knowledgebase solution Using Ansible on RHEL8 hosts from Satellite ⇐ 6.5.
