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?

• 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
  • Amazon EC2 has been known to change the MAC after reboot and this will likely cause a problem
  • The recommendation is to use the Elastic Network Interfaces (ENI) feature when a static MAC is needed
  • More information can be found here (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html)

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
