It's simply a convention to indicate the particular item is not a real package but a virtual placeholder that could be configured at build time to point to one of a selection of different providers; i.e. a recipe that requires kernel headers could have virtual/kernel in its DEPENDS rather than having to name a specific kernel recipe and the distro or machine configuration can set PREFERRED_PROVIDER_virtual/kernel to point to whatever real kernel recipe is desired.
