Virtualization Security

Dear Friends,
I am looking for the topic "Virtualization techniques for Security" and got 3 points
1.Isolation and Protection of hypervisor from external entities
eg; Privileged management VMs
2. Recursive addition of additional virtualization layers
eg: by running commodity hypervisors on top of special "Secure" hypervisors
3. Through hardware trusted platform modules(TPMs)

I have not much idea abt these points . Do you can explain it

Thanks
Anes
