These directories for building each of these images are located under the meta-virtualization directory in the build environment as recipe directories (recipe-xxx).  Dom0 and each of the images work fine.

Since each recipe only consisted of several sub-directories containing .bb files, I created a "base-files_3.0.14.bbappend" to each recipe's 'image' sub-directory (consisting of one line: hostname_pn-base-files = "<name of host>").  Now it seams that every time meta-virtualization is called bitbake "sees" the first .bbappend it comes across and tries to change the hostname regardless of which recipe I am building (i.e. If you run "bitbake -e base-files | grep ''hostname" it will always result in the same custom hostname).  Obviously this is not the proper way to set the hostname.
