Exclusively use phpVirtualBox's groups configuration rather than VirtualBox groups.

VirtualBox and VBoxManage

*) You can rename groups that contain running VMs and move / copy running VMs to groups

Answer 1

I was getting grey page with few frames and error "Resource interpreted as Script but transferred with MIME type text/html" on a Ubuntu 12.04 server.
virtualbox-4.3.18
nginx v1.6.2
php5-fpm v5.3.10
phpvirtualbox v4.3-1
The problem was, my Nginx virtual server configuration file was missing following line:
fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
/etc/nginx/sites-enabled/virtualbox.conf
--- cut ---
    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include fastcgi_params;
--- cut ---
I found this parameter on page: http://voidandany.free.fr/index.php/ins … graphique/
