Importing the Appliance in VirtualBox
From the GUI client of VirtualBox, click on the File menu and select Import Appliance.... This will bring up the import wizard which allows you to select the .ova file included in the ZEG archive.
If you prefer the command-line tool, import the appliance using the command below :
VBoxManage import /path/to/ZEG.ova
Make sure you're using a bridged network adaptor and you have a DHCP server on your LAN. Also make sure that the bridged network adaptor uses the physical adaptor that has an IP address on your LAN. Once the appliance has finished booting, a URL will be shown. Please follow the next instructions from there.
