In you Mac, open a terminal window(?) and start mysql commandline as root
$>mysql -uroot -p
enter root's password when prompted.
The create a user
GRANT ALL ON *.* to 'username'@'10.211.xxx.xxx' IDENTIFIED BY user_password;
FLUSH PRIVILEGES;
Or grant only the required privileges on the required database(s).
see the refman for user administration.
http://dev.mysql.com/doc/refman/5.6/en/user-account-management.html
You should then be able to connect to MySQL on your MAC from parallels like this on your parallels application
mysql -u username -h 192.168.0.xxx -p
enter username's password (user_password ?) when prompted.
This assumes that if there is a firewall between parallels and your mac os, that you have opened port 3306 for tcp traffic from 10.211.xxx.xxx
Good luck,
Barry.
