Abstract
Methods and apparatus for virtualization of guest operating systems (OSs) include allocating virtual machines (VMs). The VMs are assigned to each of the available hardware threads and resumed or launched for the first time. If scheduling of additional VMs is required upon exiting the VM context, another VM is selected and assigned to the hardware thread to be resumed or launched. A VM monitor is used to resume or launch a VM while the host operating system is prevented from controlling the hardware thread. A VM context structure is loaded. The thread is set to the state of the guest OS and the VM context is resumed or launched. The state of the guest OS is saved locally during a context switch to the context of the VM monitor. The VM context structure is then cleared and the host OS is allowed to control the hardware thread again.
