Can I use a virtual machine for my concurrent license server?

Yes, you can use a virtual machine as your license server. The installation of the license manager and the license administrator are the same. See this article for license server software installation instructions.

There are, however, some additional things to consider.

System requirements:

  • The license manager and license administrator can run with VMware ESX/Workstation, VirtualBox, Hyper-V, Xen, and XenServer.
  • The license manager and license administrator can be run on cloud-based virtual machines such as Amazon Web Services EC2 or Microsoft Azure.
  • The guest operating system should be Windows Server 2008 or newer, or Windows 7 or newer.
  • The client PCs running the software must be able to reach the license manager running on the license server using UDP port 5093. That port must be open both in the Windows OS as well as any VM or Instance firewalls.

Moving the VM:

  • When you activate your concurrent license on the license server, the activation is "locked", meaning that the activation is tied to the hardware of both the virtual server and the physical server. If you move this VM from one physical host server to a different physical host server, it is likely that the license activation will no longer be valid. To avoid this, use the License Administrator to deactivate the license before moving your license server VM to a different physical server. Then you can activate the license on the VM on the new physical server.
  • If you are using a more complex VM environment that includes clustering or load sharing, like an VMware ESX Server group, we recommend that you contact Golden Software Support. We can create a custom license that uses different hardware locking criteria so that the license will still be valid after an automatic move of your license server VM to a different physical server.
  • If you move your VM license server to a different host physical server, you will know if the license activation is no longer valid if the client software displays an warning "Failed to retrieve license due to client/server locking code mismatch."\
