RHEL Remote Access

Hi Experts,
I am deploying RHEL7.0 on server with 2 RHEL7.0 VMs (KVM) would like to ask about my option to access :

• Host GUI remotely ?
• KVM + VMs OS remotely?
• What is the requirement and tool ? If there is a guide for implementing this?

I have read about VNC but it is a bit complicated how things should be done.

Thanks in advance
