Virtual Firmware
Jiewen Yao, Vincent Zimmer · Apress eBooks · 2020
In previous chapters, we talked about the security design for the real firmware in the system. Now let’s take a look at the virtual firmware. Figure 13-1 is a typical type-I virtualization architecture. When the system firmware finishes the platform initialization, it launches a hypervisor. Then the hypervisor creates four domains and launches them. Each guest domain has its own virtual firmware. The virtual firmware prepares the required interface for the guest OS and launches the guest OS.
