VirtualBox was introduced on 10.2.0.2.1870 and later versions.
Enable VirtualBox: You can access the page from Virtualization > VirtualBox menu.
Now I have enabled the service and have set the proper home directory for VirtualBox where it will store all its virtual machines/database files, the weblinks to phpVirtualbox and noVNC did became available. See picture below:
Now open the weblink to phpvirtualbox and login so that we can prepare the noVNC logon for the virtual machine we installed.
Change default phpvirtualbox login password: Select File and Change password from the menu.
New phpvirtualbox login password: Now we set new password for the login.
Configure VNC port on VM setting: After you have made/installed a virtual machine you need to prepare settings on the vm for noVNC login. You need to set the VNC port and it's password proper set before noVNC login can work!.
Here in this example below I edit a FreeBSD 10.3 32-bits VM for noVNC login:
Use builtin noVNC (Browser based VNC Client):
You can control VM by phpVirtualBox and noVNC. You can open the noVNC page from the link:
Here you see also the noVNC login link you can use from bottom on the index.php
Enter the password configured by above step at the password field:
Here we see a Running FreeBSD 10.3 32-bits in VirtualBox on the XigmaNAS server managed with noVNC in this case:
It is not only limited to XigmaNAS but also you can connect any server that support WebSocket.
Tip! It doesn't have an option to auto start VMs yet so you can add this to the PostInit.
sudo -H -b -u vboxusers /usr/local/lib/virtualbox/VBoxHeadless --startvm vmname
