dongle on a virtual environment for a legacy version of CF 7.0, which has been out of updates for a while maybe is not the easy way.
Try to use the Ethernet Address or Disk serial ID instead of dongle device. since the error refers to an invalid host
Invalid host: The hostid of this system does not match the hostid specified in the license file.
Also be sure the license file can support 7.0 , verion 7.2 which is the current one does not support the use of previous versions.
