In virtualized environments the Diva softIP Software license is bound to your system with the PC fingerprint only. The WIBU-Key USB dongle cannot be used for licensing purposes, because an access to the USB is not supported by virtualized environments. The license is bound to several hardware components of the PC, including the MAC address. Each virtual machine (VM) has its own MAC address; therefore, a separate license is required for each active VM with the Diva softIP software installed. Separate licenses are also needed for environments with parallel services, e.g., VM 1 operates a fax server using the Diva softIPSsoftware and VM 2 operates an IVR system using the Diva softIP Software. Also, since the Diva softIP software license is bound to the hardware components as well, the Diva softIP Software license will become invalid if you move the VM to another hardware platform.
You should assign a fixed MAC address to avoid that it changes, e.g., after copying the virturalized environment to a different place, or after restarting or reconfiguring the PC, otherwise the Diva softIP Software license will become invalid.
If two VMs are used for failover only and are not active at the same time, the same MAC address may be assigned to both VMs, the active VM and the passive failover VM. In this case, the Diva softIP Software license can be installed on both VMs, but you need to make sure that only one of the VMs is active, otherwise it may cause a MAC address conflict and the network communication may be interrupted.
