Detailed Information on how to configure KVM for remote access

First of all I'm not a Linux guru or scripting wizard and so please realize that in answering. I'm attempting to configure a RHEL 7.4 server as a KVM host and I want the hosted VMs to be accessible by other systems in our domain through a VNC session that allows 2 monitors. Here's what I've configured so far:

• a RHEL 7.4 server
  *The server is hosting a RHEL 5.11 KVM
  *xWindows is running on all

Goals:
* 5.11 KVM to connect to domain/LAN and receive DHCP address
*Need to access the KVM from workstations in the domain running VNC
*Workstations need VNC sessions to display on 2 monitors

5.11 currently runs an DGI app that we intend to upgrade to RHEL 7.x platform on KVM on the server above.

How can I best achieve the goals outline above? Thanks!
