Ahh...
If I'm reading your post correct, then that's not how Active/Active works...
Active/Active denotes the fact that both units can serve virtual servers simultaneously... Not both serving the same VS and IP address at the same time... To configure it, simply place into active/active config (A checkbox under the HA options) and then assign individual VS's to either unit 1 or unit 2. The VS will then 'live' on the unit specified. If one of the units goes down, the other uni will takeover BOTH units load.
So you'd have 2x VS's. One for MySQL A, one for MySQL B. MySQL A VS would be on unit 1, MySQL B VS would be on unit 2. Then simply configure web A to use MySQL A VS and web B to use MySQL B VS.
