Sure. Let's use Centos. In short:
0. on the VB host install and configure a web or FTP server*,
1. D/L the Centos installation ISOs, unpack them to your docroot and set up the repo,
2. D/L the Centos netboot ISO, create a new VB guest and boot it from the ISO pointing to your local install WWW/FTP/whateverelse tree.
* You could also do things the PXE way with TFTP, DHCP and NFS.
