I've been trying to get past this issue for a couple of weeks now, but I can't get to a lower level error to find out what's causing it. I've run runcluvfy.sh but it gives no clue as to exactly what is causing the error. The output from the node connection verification:
[oracle@ol7-121-rac1 grid]$ ./runcluvfy.sh comp nodecon -i enp0s8 -n ol7-121-rac1,ol7-121-rac2 -verbose

I can ping from one node to the other and from each node to itself, I can also ssh between nodes and from each node to itself.
This driving me insane, so if anybody has any ideas I'd love to hear them.
I am installing Grid 12c (12.1.0.2) on to Oracle Linux 7 which is a guest VM (Virtualbox) on a Windows 7 host.
