Sorry, I haven't read the bottom of your email. But, I believe that when you setup the cloudstack database with the command:
"cloudstack-setup-databases" you could use th -i flag with a value like localhost or 127.0.0.1 then you should not have problems. Or if you do not wantto configure everything again, you can access the database that CS has setup and then you could change the parameter called host on table cloud.configuration to 127.0.0.1, then you should not have problems.
