Licensing on Virtual Machines

Finding Ways to Tame Virtual Machines

Virtual Machine (VM) software has been a major factor in increasing computer utilization and efficiency. VM software allows users to segment a computer into multiple virtual systems, each with its own copy of an operating system that acts fully independent from the others. For software vendors, this “machine replication” can be a problem, one that can make profits virtual too.


Attack of the Clones

Since licenses are usually tied or node-locked to a host using the Ethernet hardware address, this means that users can also gain access to extra application licenses – in most cases exceeding the scope of their license agreement.


RLM on Virtual Machines

Software licensing vendors are helping ISVs address this issue. For instance, starting in v5.0 of Reprise License Manager™ (RLM), Reprise Software added the capability to disable node-locked licenses or license servers when running on virtual machines.


RLM detects VMs and disables license servers and other specially marked licenses. Disabling licenses on Virtual Machines is useful for node-locked, uncounted licenses in order to prevent these licenses from being used on multiple cloned systems within virtual machines.


By being able to disable licenses on VMs, software vendors can gain more control over how their software is used and priced. Software vendors can charge fair value for licenses that can run in a VM, matching the extra value and flexibility obtained in exchange for a potentially higher price. At the same time, some vendors might consider lowering the cost of licenses that are disabled on VM. This strategy is not unlike how some vendors use time-zone-limited licenses to reduce the cost of their basic license while charging higher fees for licenses that can span larger geographies.


Have it Your Way

Because the license itself contains the parameter that controls whether it will or will not run under VM, vendors can deliver both kinds of licenses to their customers—disabled and non-disabled. This is important because it allows vendors to issue short-term VM-capable licenses for testing and evaluation purposes, but disabling other licenses for long-term production deployment.

What’s the difference?

Reprise License Manager (RLM)

Software License Manager

RLM provides runtime checking that verifies that your application is licensed to run and that the current usage of your application is within the limits you have ser every time your application runs.

As a Software publisher, you integrate RLM into your product, and RLM keeps track at runtime of who is using the licenses of your software.

RLM can do this entirely within the client library (linked into your application), or, more commonly, your application makes a request of the RLM Lincese Server to check out a license.

The lincese server runs either on your customers network, or in the cloud if you are using our RLMCloud™ service.

RLM provides runtime checking that verifies that your application is licensed to run and that the current usage of your application is within the limits you have ser every time your application runs.

RLM Activation Pro

Software Activation Manager

Activation Pro is
used once when your customer purchases your software in order to retrieve the license which is specific to that customer.

Software Activation’s purpose in life is to get the licenses for your product to your customers with a minimum of fuss.

Activation Pro also has a server component wich we call the activation server.

Your application contacts the activation server and supplies a short text activation key, and in exchange, the activation server returns the license which enables your product.

Generally, this is done once, right after your customer purchases your software, not every time your software is invoked.
