Redhat 7 desktop to workstation

redhatrhel7subscriptionyum

I installed a RedHat out of an installation cd, registered my entitlements, all that stuff.

As part of my subscriptions I have both Red Hat Enterprise Linux Workstation and Red Hat Enterprise Linux Desktop. (plus a tons other)

My problem is currently the product installed is a Red Hat Enterprise Linux Desktop

Is there a way to change it to a RHEL Workstation without reinstalling everything?

Have you tried changing the channel via subscription-manager?

What is the output of sudo subscription-manager list --consumed

Either way, you won't need a reinstallation.

From a licensing perspective, the answer depends on the hardware you've installed onto...

Think of it like this: RHEL Desktop (aka Client) is meant for single-socket computers. Workstation is intended for more powerful workstations (dual-socket).

All distributions (Client/Workstation/Server) use the same kernel and obviously the same installation media. The main difference is the default set of installed packages. You're free to install whatever you want in terms of packages, but in order to be "supported", your hardware should fit within the bounds set in the chart below:

You can use the lsb_release command on various Linux distributions:

lsb_release -i -r

This will tell you the Distribution and Version and is a little bit more accurate than accessing files that may or may not have been modified by the admin or a software package. As well as working across multiple distros.

For RHEL, you should use:

cat /etc/redhat-release

Docker – How does yum with Red Hat Network Subscription work inside the rhel Docker images

Red Hat carries a patch to docker called the 'secrets' patch which mounts the entitlement information into containers when they are run.

You can see the a better description of the patch and a link to the upstream PR in the projectatomic/docker repo:

https://github.com/projectatomic/docker/tree/docker-1.13.1-rhel#add-rhel-super-secrets-patchpatch

Note, you'll need to select one of the branches (the link goes to the 'docker-1.3.1-rhel' branch) to see all the carried patch information.
