I do this as my day job, so believe me when I say that an embedded flash - even if intended for an Intel based SBC (***) - is unlikely to run in a VM. A PC Operating System has a huge installer, much of which consists of drivers for the vast array of hardware that the installer might find in a target PC. An embedded OS image has none of that. The image will typically only contain drivers for the exact chipsets found on the SBC. So, unless you can create a VM which exactly duplicates those chipsets, then the image cannot run.
Secondly, embedded devices don't have installers. The image will typically be a
flash image as I've already mentioned. A flash image is more akin to a RAM memory dump than a disk drive (embedded devices rarely have disk drives of any kind). A memory dump contains no filesystem and no installer. Copying that memory image onto a virtual hard disk will be entirely useless.
I suggest that you browse the forums of the OpenWrt project and see what you're supposed to do with the file you downloaded. Is anyone else on that forum talking about running it on VirtualBox? (and I still don't understand what the point of that would be - embedded devices are physical by nature, not virtual).
(***) And I just checked this. The
Ventana SBC that I found with a quick search (possibly there is more than one model) is based on a dual core
ARM, it is not any kind of PC. So add that to the list of dead ends: an Intel based WinPC VM cannot possibly run an ARM based flash image.
