One of the issues with using VMWare fusion is that the IP addresses for your guest OS images can change when you restart them.
Annoyingly, they can also change when you suspend/resume them!
When creating a small 'farm' of machines and linking the hostnames together, this can be a pain in the proverbial!
Luckily Will Warren has the solution here https://willwarren.com/2015/04/02/set-static-ip-address-in-vmware-fusion-7/ - cheers, Will!
