Troubleshooting Tip: Fail to integrate FortiGate in VM mode

When integrating FortiManager and FortiGate, a pop-up error 'Unsupported device model' appears:

On CLI:

Request [fgfm fos:7689:27]:
{ "client": "fgfm fos:7689",
..
"FortiGate-VM64-KVM", "sn": "FGVM0XXXXXXXXX", "source": 1, "tab_status": "<unknown>", "version": 700}, "from": 1}, "url": "dvm\/cmd\/manage\/device"}], "session": -1}
Response [unknown]:
{ "id": 27, "result": [{ "status": { "code": -20026, "message": "Unsupported device model"}, "url": "dvm\/cmd\/manage\/device"}]}

On the latest FortiManager firmware version (v7.4.7, v7.6.3, and onwards), a configuration has been added:

Bezza-kvm30 # config system global

(global)# set fgfm-allow-vm 
disable    Don't allow VM platform connection in FGFM.
enable     Allow VM platform connection in FGFM.

(global)# set fgfm-allow-vm enable

(global)# end

By default, the 'fgfm-allow-vm' is disabled. However, a managed device (in VM Mode ) that integrates FortiManager needs to enable the 'fgfm-allow-vm'.

After enabling the fgfm-allow-vm, refresh the FortiManager and add the FortiGate from the FortiManager.
