We used "Debian GNU/Linux 8 (64-bit)" and in the release notes I see a "OS Type: Other Linux 64-bit (or Debian 8.0 or 9.0 64-bit)" for vmware [1].
However, let me change this to "Other Linux 64-bit" and verify if it makes any difference here. René [1] http://docs.cloudstack.apache.org/en/4.11.1.0/upgrading/upgrade/upgrade-4.5.html#update-system-vm-templates
