I found it but this is only partially the answer. I found 
PREFERRED_PROVIDER_virtual/kernel ?= "linux-yocto" in qemu.inc but there 
is no recipe for linux-yocto. There are recipes for linux-yocto_3.* , 
linux-yocto-tiny, and linux-yocto-rt_3*. 

Somewhere during the build process something is appending to linux-yocto. 
I will keep looking but if someone knows the answer please respond. 

Thanks,

The part before the '_' is the package name, the part after is is
version. So, linux-yocto, linux-yocto-tiny and linux-yocto-rt are three
different kernels, each of which can have multiple versions at the same
time.

You get automatically the highest available version a package unless the
version is specifically pinned down somewhere (e.g.,
PREFERRED_VERSION_virtual/kernel in the configs or DEFAULT_PREFERENCE in
the recipes themselves).

The kernel is normally specified in the machine conf file; grep for
PREFERRED_PROVIDER_virtual/kernel.

I successfully built core-image-minimal.  I now what to understand how the 
build determine what linux kernel it will be using because the next step I 
will want to do is add my own recipe that references my own kernel.  I 
have not been able to find where the linkage to specific kernel is. Can 
someone  provide an answer.
