Discovering a virtualized Oracle server

I am about to discover a virtualized Oracle server for the first time.  The SP Installation guide says this:

The server must be under Host Configuration so the ASM Script (oracle-asmdisk. pl for Linux and ASMDiskDetection.ps1 for Windows) can be pushed to the server to retrieve the internal Disk/Array WWN information.

I have questions.  If the database isn't configured as ASM,can I skip all of this?  Since the server is a VirtualMachine, should I try to set up some sort of minimal discovery process?  Is it even possible to set up a second Generic-RSC instance on a collector?
