== Using a .ova file ==
{{ImportantMessage|text=Due to file system limitation, the OVA file may be delivered as a splitted compressed 7zip archive. In this case, use 7zip compressor to rassemble the original compressed .7z file (for example, see [http://www.techulator.com/resources/6601-How-split-join-files-using-7-zip-free-tool.aspx here]).}}
{{ImportantMessage|text=By default, released OVA files require host CPU's hardware virtualization extensions such as Intel VT-x and AMD-V. If these extension are disabled at BIOS level, VirtualBox can't run imported virtual machine. Two options are available to solve this issue:
#enable such extensions at host machines's BIOS level
#disable the use of such extensions in the virtual machine configuration; to do that, please open ''Settings->System->Acceleration'' box in the VirtualBox Manager. Please note that '''this reduces the performances of the virtual machine significantly'''.
