Use:

bitbake virtual/kernel -c menuconfig

Then from the menuconfig, save the configuration file to where your 
bitbake recipe will pick it up. Otherwise, your changes will be lost the 
next run of the kernel.

And bitbake is smart enough to figure out the dependencies, so just running:

bitbake virtual/kernel

will install and deploy the new kernel after you've changed the 
configuration. All those "-f" (force) options aren't needed, and you 
also don't need to specify all the single steps. You can add a "-c 
deploy" if you like.
