indicate compatibility with CentOS 6.2, 6.1 and so on.

-  RHEL versions 6.3, 6.5, 6.6 and 7.0
-  CentOS versions 6.8, 7
-  Ubuntu 16.04 LTS, 18.04 LTS

   .. note:: There is a known issue in 6.7 U3 - 6.7 U3f where a mailformed OVA could crash vCenter services (for more information see `here <https://mail-archives.apache.org/mod_mbox/cloudstack-users/202005.mbox/%3CCAMvtBPNQqbe0XEsHyjFMror7HRvj-c%3DfEe7y12NfCDQSFTYgqQ%40mail.gmail.com%3E>`_).
