I want to setup virtual network with 3 guest OS(FreeBSD) for testing scalable webapp. The first one should be only MySQL master server. Second and Third will be slaves with read only MySQL's and webservers.
Currently I have installed 3 identical virtual machines. My problem is setting up the network, so 3 guests can see each other and Host OS(Win7) can see webservers.
How I should configure virtualbox network settings? What network configuration I should give in FreeBSD and host OS?
And in general. Is this a good way to do development/testing of distributed webapp on local machine?
Edit: Some progress, but not ideal. problem in details: https://forums.virtualbox.org/viewtopic.php?f=1&t=49150
