Clustering Network Validation Warning

I have some cluster warnings after running the cluster validation wizard in my test environment on Virtual box Environment.
I have 2 Server (SQL-E and SQL-F) and 1 Domain Controller Server I should able to ping each other:
node1 -
10.10.10.50

node 2
10.10.10.60

both nodes connected to DC server(10.10.10.10 = iscsi target which is Domain controller Server)
When I validate to create the cluster. Now i receive 2 warning:
validate ip configuration
validate network communication
Going to "validate ip configuration" i see on both nodes a Local Area Connection 11 with an APIPA 169 address but looking on both servers i don't see this Local Area Connection 11 in network sharing center.
QUESTION1: How do i solve the below Error?
Going to "validate network communication" i see the warning below:
--node1 and node2 are connected by one or more communication paths that use disabled network. These paths will not be used for cluster communication and will be ignored. This is because interfaces on these networks are connected to an iscsi target. Consider adding additional network to the cluster, or change the role of on or more cluster networks after the cluster has been created to ensure redundancy of cluster communication.
--the communication path between network interface node1-nic1 and network interface node2-nic1 is on a disabled network.

This is driving me mad and I tried to ping back and forth with all servers. i should be able to reach. I do not have any clue to solve this issue. Can somebody help me please.
