XLS reporting support

If you are on Virtual Appliance 1.25-1+ then just use it, nothing is required, everything is already installed.
In any other case you would need to install a few Perl modules to make it work.
You will be prompted for its install when you click on the Excel report.

Install Perl module perl-Spreadsheet-WriteExcel, use one of methods below:

• YUM
  PDF modules (including dependencies) can be installed from EPEL repositories (fedoraproject.org/wiki/EPEL)
