Abstract
A virtual machine (VM) operating system (OS) configuration system includes a processor, wherein the processor is arranged to execute a host VM, a hypervisor, a root module, and a guest VM. The host VM is arranged to generate a driving signal for driving a booting of a guest VM. The hypervisor is arranged to generate a first trigger signal according to the driving signal, for triggering verification of a descriptor. The root module is arranged to verify the descriptor according to the first trigger signal to generate a verified descriptor, and store the verified descriptor in a protected memory, wherein an OS of the guest VM is configured according to the verified descriptor.
Claims13
A virtual machine (VM) operating system (OS) configuration system, comprising:
- a processor, arranged to execute:
- a host VM, arranged to generate a driving signal for driving a booting of a guest VM;
- a hypervisor, arranged to generate a first trigger signal according to the driving signal, for triggering verification of a descriptor;
- a root module, arranged to verify the descriptor according to the first trigger signal to generate a verified descriptor, and store the verified descriptor in a protected memory;
- and
- the guest VM, comprising:
- a boot loader, arranged to perform a check operation upon the verified descriptor, to generate a checked descriptor, wherein in response to the checked descriptor not existing an error, at least one security-associated node is added to the descriptor in order to generate the checked descriptor, for configuring the OS of the guest VM.
A non-transitory machine-readable medium for storing a program code, wherein when loaded and executed by a processor, the program code instructs the processor to execute:
- a host VM, arranged to generate a driving signal for driving a booting of a guest VM;
- a hypervisor, arranged to generate a first trigger signal according to the driving signal, for triggering verification of a descriptor;
- a root module, arranged to verify the descriptor according to the first trigger signal to generate a verified descriptor, and store the verified descriptor in a protected memory;
- and
- the guest VM comprising:
- a boot loader, arranged to perform a check operation upon the verified descriptor, to generate a checked descriptor, wherein in response to the checked descriptor not existing an error, at least one security-associated node is added to the descriptor in order to generate the checked descriptor, for configuring the OS of the guest VM.
