Hah!  Even better, it works the first time and every time, if I start
with a kdestroy:

     1. From Virtual Machine Manager open ipa2
     2. Login as dean
     3. Open a terminal
     4. kdestroy
     5. ssh dean@desktop2
     6. logout
     7. ssh dean@desktop2
     8. logout

Now, the fun starts.  Why do it do that?
