- The VE license server itself
- VE license server package
- A suitable Linux instance to be used as the VE license server. This instance must run
- in a supported cloud environment,
- in a supported VMware environment, or
- on a supported physical server.
- Correct firewall settings
- The VE-capable Charon emulator software
- For general VE mode: must run on a Charon host with appropriate network access to the VE license server (see restrictions for VMware environments in the section Charon VE-Capable Emulator and Management Software below).
- For AutoVE mode: a Charon instance launched from a compatible Automatic Licensing marketplace image. AutoVE server and clients must be in the same cloud environment. Please note that the AutoVE definitions must be added before the first launch of such an instance.
...
The license server package must be installed on a supported Linux instance. This instance can run in a supported cloud, in a supported VMware environment, or on a physical host. It is recommended to run the VE license server on a dedicated system to avoid license invalidation caused by changes to the system which are more likely to occur on a system used for other purposes as well, for example, to run a Charon emulator. It is also recommended to install a backup license server to ensure continued operation in case of a failure or invalidation of the primary license. AutoVE server and clients must be in the same cloud environment.
Currently Supported Cloud Providers
...
- Red Hat, CentOS, or Oracle Linux (64-bit) versions 7.x or 8.x
- Rocky Linux 8.x
- Red Hat, Oracle Linux, and Rocky Linux 9.x
- Support for Amazon Linux 2023 is planned to start starting with VE license server version 2.4.1.
Only 64-bit operating systems are supported. The root filesystem type must not be BTRFS.
Other Software Requirements for the VE License Server
Please note the following additional requirements:
- The Btrfs file system is not supported as a root file system for a VE license server.
- To unpack the shell archive containing the installation kit, the following utilities are required: gzip, md5sum, cksum, gpg, tar, and openssl
Hardware Requirements for the VE license server
Basic hardware requirements (cloud instance capabilities or VMware host configuration) for running a dedicated license server:
...
Dedicated System for the License Server (recommended)
If the system is dedicated to running the license server, its hardware configuration must satisfy the requirements of the selected Linux operating system.
Additional hardware requirements (cloud instance capabilities or VMware host configuration) for running the emulator software on the same system:
License Server Combined with Charon Emulator Software (not recommended)
If the license server is combined with the Charon emulator software on the same instance, the instance used must satisfy the requirements of the Charon emulator host and all instances that will run on it. Please refer to your product-specific documentation for more information:
- For Charon-SSP, refer to the Charon-SSP user's guide of your emulator version for details (see Charon-SSP for Linux).
- For Charon-PAR, refer to the Charon-PAR user's guide of your emulator version for details (see Charon-PAR documentation).
- For Charon-AXP/VAX, refer to the user's guides for Charon-AXP or Charon-VAX.
...
Please note, that a dedicated license server system is the recommended configuration.

Additional Linux Host Requirements for AWS cloud
...
VE License Server Installation on Amazon Linux 2023
Only for VE license server versions earlier than 1.1.23.In the AWS cloud, an IAM role allowing the ListUsers action (IAMReadOnlyAccess in the example below) must be attached to the VE license server instance. This can be done during the launch of the instance as shown in the sample below.
Alternatively, the role can be set/changed by selecting the instance, right-clicking on it, and selecting Security > Modify IAM Role (in the older AWS console, use the Action menu). If such a role has not yet been defined, please refer to Creating and Attaching an AWS IAM Role (versions < 1.1.23 only) and to the documentation provided by AWS for additional information2.4.1 and higher (older versions are not supported to be run on Amazon Linux).
By default, Amazon Linux only installs a minimal gnupg package. This is not sufficient to unpack the VE license server kits archive. An attempt to unpack the archive will result in the error gpg: uncompressing failed: Unknown compression algorithm. To swap the minimal for the full package, use the following command:
# dnf swap gnupg2-minimal gnupg2-full
VE license server versions earlier than 1.1.23 only - IAM role requirement
In the AWS cloud, an IAM role allowing the ListUsers action (IAMReadOnlyAccess in the example below) must be attached to the VE license server instance. This can be done during the launch of the instance as shown in the sample below.
Alternatively, the role can be set/changed by selecting the instance, right-clicking on it, and selecting Security > Modify IAM Role (in the older AWS console, use the Action menu). If such a role has not yet been defined, please refer to Creating and Attaching an AWS IAM Role (versions < 1.1.23 only) and to the documentation provided by AWS for additional information.
AWS region support
If a new region in the AWS cloud is not yet supported by the VE license server, creating a C2V file will fail with the error message:
Failed to verify the instance document's signature!Sanity check failed on AWS cloud.
Should you receive this error, please contact your Stromasys representative.
Additional Linux Host Requirements for IBM cloud
For the VE license server to work properly in the IBM cloud, an API key must be created and installed. Please refer to Creating and Installing an IBM API Key.

Firewall Considerations
Communication Between License Server and Client Systems
...
- Charon-SSP 4.2.x and later
- Charon-PAR 3.0.6 and later
- Charon-AXP/VAX planned for version 4.12 and later (Linux versions only)
Stromasys or your Stromasys VAR will provide you with the software or a download link. In certain cloud environments, Stromasys may offer prepackaged Charon VE images on selected cloud marketplaces. If you use a Charon host in the cloud and the instance was launched from such a prepackaged image, the required VE-capable emulator software is already installed (refer to the respective cloud-specific Getting Started Guide for more information).
