vbox Host only interface IP configuration, access denied

Hi everybody,

I'm encountering trouble of denied access :

$ /usr/local/bin/VBoxManage hostonlyif ipconfig vboxnet0 --ip --netmask
VBoxManage: error: Code E_ACCESSDENIED (0x80070005) - Access denied (extended info not available)
VBoxManage: error: Context: "EnableStaticIPConfig(Bstr(pszIp).raw(), Bstr(pszNetmask).raw())" at line 242 of file VBoxManageHostonly.cpp

$ cat /usr/local/etc/vbox/networks.conf

$ pkg info virtualbox-ose
Name : virtualbox-ose
Version : 6.1.36
Installed on : Fri Sep 16 18:57:40 2022 CEST
Origin : emulators/virtualbox-ose
Architecture : FreeBSD:13:amd64

Has somebody solved this problem ?

Thank you very much for your suggestions.
just take a look to FreeBSD Handbook ,Virtualization Chapter 22. Maybe is just a question of permission
