Hi,

I have created a project and create two different network, and have configured a router and have mapped both the network, have configured security groups to allow icmp and no firewall rules as well but the vms were not able to communicate between themselves.

but when i set gateway for the router which i created the vm started to communicate, is setting gateway mandate, in my scenario the vm traffic ideally need not go to external network itself.

Using libguestfs-tools you can change original QCOW2 images of your VMs to have 2 VNICs
as described in https://ask.openstack.org/en/question...
Then every VM may be created belonging both private networks at a time. Hence, you wouldn't need router at all.
