You cannot create an installer out of an installed version of Mac OS, nor would a question about such specifics about Mac OS be on topic here. What you can do is to convert the virtual disk image to a raw disk image, to write it to a hard disk which should boot. You can do this with VirtualBox via vboxmanage clonemedium disk input_file --format RAW output_file. Tools like gnome-disks provide an easy way to write such raw images to hard disks, just rename the file extension to .img and click restore image, or use dd on the command line. Beware that you destroy all data that was on the drive selected as the target for the raw image.

Here is a very similar question on Unix SE:

And another answer that is very similar considering the commands used:

these steps:

1. Convert the vmdk file to vhd (use a tool to do so)
2. Flash the vhd file to your USB devices.
