Subject Re: Problem Adding the Host
Date Fri, 10 Mar 2017 20:48:47 GMT
Ok, I think you can take a look here:
https://help.ubuntu.com/community/KVM/Networking#Private_Virtual_Switch_.28Guest-Only_Network.29

What I meant is the following: create four networks of that type. These
networks will be between your KVM box and the VMs, which will run ACS, NFS,
and hypervisors hosts (KVM?). Let’s call them Network1, Network2, Network3,
Network4.

You then attach each one of these VMs in each one of the networks, every VM
will have 4 NICs. Then, you select a network to be the public one (let’s
say network 4). Then, you can create a forwarding rule for your KVM box, to
forward packets from the public network (network 4) to the world. Your box
will then work as a router for the VMs public network. Do not forget, that
the NIC attached Network 4 has to be the Public NIC configured in ACS.

I have created an environment just like that using Virtualbox, I used 4
VMs, one for ACS, one for the NFS, and two for hosts (I used XenServer)

Did you understand what I tried to explain?
