Licensing - I am unable to borrow a license from a Virtual Machine license server


In Vivado License Manager (VLM) a license that was set up to allow borrowing cannot be borrowed from the machine I am using.

I am receiving the following message:

NOTE: This license cannot be borrowed because the server is registered as a virtual machine, and the current machine is a physical machine. 
This specific configuration is not supported for borrow at this time.

What is the reason for this?


With the Flex licensing software used by Vivado, there is a limitation that will not allow activation licenses served on a virtual machine to be borrowed by a physical / bare-metal machine.

To prevent corruption of the Trusted Storage on the client machine, this combination has been disabled.

As shown in the following table, virtual machine clients are allowed to borrow from either a physical or virtual machine server, and a physical client can borrow from a physical server.
