OK, I believe that I have come up with the answer to my questions.

Rather than using "--domain virt --local=/virt/", I need to use 
something like:
       "--domain=virt,192.168.122.0/24,local" or
       "--domain virt --local=/virt/ --local=/122.168.192.in-addr.arpa/"

For the case of no domain name, I am not sure that 
"domain=,192.168.122.0/24,local" would work but
      "--local=// --local=/122.168.192.in-addr.arpa/" should work.

Comments?
