VMware/Linux: Redhat Virtualization Licensing (vmware)
Not sure how many people out there know about it yet, but RedHat is on the “band wagon”. Time had come up to renew our licenses, and we found the RH for VMware on CDW website.
Turns out this can definitely save a lot of money! Check out Redhat pricing.
The licensing comes in the following forms:
Now for the fun part:
These are licensed per socket of the ESX host, not per virtual cpu. So for us, each of our ESX hosts has 4 sockets (physical cpu). So this means that the cheaper basic and standard subscriptions are out for us. Now, we will have to buy “Red Hat Enterprise Linux Advanced Platform for VMware”. Even though the unlimited sockets is the higher costs of all the “VMware” licensing, we still come out a LOT cheaper!
Note: Be careful if you inquire about this licensing. We almost sent in our order with CDW that was quoted using virtual CPUs instead of physical ESX host CPUs. The bad thing is it was CDW that told us that it was based on VCPU. Also, to make it clear, the number of guests is how many installs of RedHat you can have under that license. So if you get the 10 guests Advanced Platform license, you get to run 10 Redhat virtual machines on your ESX host under that license.
this interesting new licensing policy caused us to switch to SuSE, 1 license gets you unlimited installs on an ESX host…

I appreciate your efforts to share this information. Redhat makes it painful to find and understand this information. And based on what I’m picking up as I wade through undertanding this, Redhat is about to change the licensing model again (effective April 1).
I do have a question though. I found your site and this explanation above via the following post on VMware’s site: http://communities.vmware.com/thread/189522 .
I would like to get a clarification on it though. When asked about the number of licenses you purchased you ultimately said you bought 6 of the RHEL-AP for VMware (inlcudes 10 guests/license) to cover your 60 Redhat VMs. However, you also indicate your have 4 4-core servers in the ESX farm. Aren’t you required to purchase the licenses on ALL the cores? In your case, I would expect that to mean you had to buy 16 licenses. You would then be able to support up to 160 Redhat VMs (because of the pooling).
Or am I missing something?

The virtual licensing is different from their physical. The underlining server architecture decides which RedHat level your licensing will be at. Since we are quad, quad core, that meant were were at the higher Red Hat Enterprise Linux Advanced licensing level instead of basic.
we were hoping that we would be able to run a mix of basic and advanced licenses in the vmware environment, but due to our vmware esx server architecture, we could not. The virtual licenses are setup to be sold in “blocks” of 10 for advanced. So we had 3 vmware esx servers, ~60 RH Virtual Machines, so we wound up by a total of 6 RedHat Advanced Edition blocks. Each of these 6 blocks allows licensing for a total of 10 virtual machines each. That gives us 60 total licensed Redhat VMs.
We are going to dual quad core servers coming soon and that will take us out of the advanced edition licensing, so we should be able to order blocks of the Basic version. Does this help?
