Original Abstract Submitted
A virtual machine (VM) operating system (OS) device assignment system includes a processor, wherein the processor is configured to execute a host VM, a hypervisor, a device assigner, and a guest VM. The host VM is arranged to generate a driving signal for driving a booting of the guest VM. The hypervisor is arranged to generate a first trigger signal according to the driving signal, for triggering assignment of at least one device. The device assigner is arranged to modify a descriptor to generate a modified descriptor for assigning the at least one device among a plurality of devices to the guest VM, and install the modified descriptor into a protected memory, wherein an OS of the guest VM is configured according to the modified descriptor.
