Shareable disks in Virtual Box

Recent versions of Virtual Box (4 and up) have support for “shareable” disks. This feature lets you build a RAC without using Openfiler or some other sort of SAN/NAS simulation software. Saves you one virtual machine in the setup.

I am not sure if this setup can be used with Oracle 10g RAC and whether this feature is stable enough, but here is an article by Tim Hall that describes Oracle 11g RAC built around this kind of disks.

Update: created shareable disks in 3.2.12 and used them under OEL 5.2 (you still need some clusterware-like software to properly share the disks).
