Connecting two mininet in two different VM with the same Ryu Controller

Question

I am using virtual box on Windows 10 and running two VMs with ubuntu 18 concurrently Both of them have mininet installed.

In the VMs settings I have set the network as Host Only adapter and in advanced selected allow VMs so that both the VMs can communicate.

I have tried $ ifconfig -a in both VM and one have ip 192.168.56.101 and the other 192.168.56.102 and tried pinging from one VM to another and it works.

I am running mininet in both of them as given below and connected both of them to the same Ryu controller I which is running on VM1.

Fig: The switches are connecting to the controller

I have used the following commands to do this:

1. In VM1 terminal1:

    ~$ ryu-manager --ofp-tcp-listen-port 6653 ryu/ryu/app/simple_switch_13.py
   

2. In VM1 terminal2:

    ~$ sudo mn --topo single,2 --controller remote,ip=192.168.56.101:6653
   

3. In VM2 terminall:

    ~$ sudo mn --topo single,2 --controller remote,ip=192.168.56.101:6653
   

Now my questions are:

1. How to ping VM1->hosts from VM2 mininet and vice versa?
2. If ping can be done then how to put VM1->h1 and VM2->h1 in the same VLAN and VM1->h2 and VM2->h2 in the same VLAN using ovs commands or anything?
