Thanks - so the CPVM talks to the vnc ports on your hosts on the
management network. I guess there should be a way to turn off
name-resolution in such cases as your deployment where you don't allow
any public traffic on your management network. Either that or we need
to note this in our documentation somewhere. Could you please point to
this thread and file a bug report?
