Can I License KEPServerEX on a Virtual Machine, Cloud, or Cluster?


Last Update: 2018/11/27

Questions

  • Can KEPServerEX be licensed on a Virtual Machine?
  • How do I license the KEPServerEX in the Cloud?
  • Are multiple licenses required for licensing KEPServerEX on a Cluster?
Answer
  • Yes! KEPServerEX 5.20.396.0 and greater can be installed and licensed.

Licensing on VMWare ESXi

  • Verify that the address Type is set to static for the VM
  • If the address type is dynamic, a new MAC ID will be assigned during certain events such as copying or migration or maybe even after a reboot
  • To set a static MAC ID, following the below steps:
  1. Power down the virtual machine.
  2. Locate the virtual machine in the vSphere Web Client by selecting Related Objects | Virtual Machines.
  3. On the Manage tab, select Settings | VM Hardware.
  4. Click Edit.
  5. On the Virtual Hardware tab, expand the network adapter section.
  6. In the MAC Address section, select Manual from the drop-down menu.
  7. Type a static MAC address.
  8. Click OK.

Licensing on VMWare Workstation

  1. Power down the VM and locate the VM's vmx file.
  2. View in a text editor and make the below changes

Add:

ethernet0.checkMACAddress = "false"

ethernet0.addressType = "static"

ethernet0.address = "11:22:33:aa:bb:cc"

Remove:

ethernet0.addressType = "generated"

ethernet0.generatedAddress = "11:22:33:aa:bb:cc"

ethernet0.generatedAddressOffset = "0"

Licensing on Microsoft HyperV

  • HyperV defaults to "Dynamic MAC Address Regeneration" which will cause a break after migration
  • Setting MAC Address Regeneration to Static solves this problem.

Migrations or Moves

  • Moving or migrating a virtual machine running a licensed instance of KEPServerEX is supported as long as the virtual machine's MAC ID, VM UUID, or VM GenerationID does not change
  • MAC IDs can change under a wide variety of circumstances, depending on the specific software and action taken
  • Setting a Static MAC ID in a virtual machine with migrating hosts can limit MAC ID changes
  • If the virtual machine prompts for I moved versus I copied, choosing I moved can lessen the likelihood of a MAC ID change

Snapshots

  • Reverting to a snapshot will break the license, but the license can be reactivate or repaired using the License Utility.

Clones/Copies

  • Cloning or copying a virtual machine will result in a broken license that cannot be repaired
  • This is in violation of the User Licensing Agreement (ULA)

Licensing in the Cloud

  • Some cloud environments (Azure and possibly Amazon EC2 and Google Compute) are only supported in v6.0 and greater
  • Licensing will break after every reboot on older versions
  • AWS EC2

Licensing on Clusters

  • On a cluster where multiple computers are acting as one without a virtual environment, a separate license is needed for each computer in the cluster
