Install lsscsi in Linux, then you can see the device as "LUNs". Hard to know what Oracle VM is or what it is looking for. Any reason for "Oracle VM"? I'm ok if it's a requirement, but I do know that Oracle has a way of taking very very different technologies and putting them under a common umbrella name... thus Oracle VM may be a worthless way of describing what you are actually trying to install/do.

If you are wanting something SAN-like, you could make your local drives into iSCSI targets, but normally, that so you can expose the LUN across the network, though in theory you could talk to yourself.
