In one embodiment, a request to transition control to a virtual machine (VM) is received from a virtual machine monitor (VMM) and a determination is made as to whether the VMM has requested a delivery of a fault to the VM. If the determination is positive, the fault is delivered to the VM when control is transitioned to the VM.

In one embodiment, a predefined behavior of a virtual machine monitor (VMM) with respect to one or more virtual machines (VMs) is identified, and processor-managed resources associated with the one or more VMs are utilized based on the predefined behavior of the VMM.

In one embodiment, a method for handling privileged events in a virtual machine environment includes detecting an occurrence of a privileged event, determining which one of multiple virtual machine monitors (VMMs) is to handle the privileged event, and transitioning control to this VMM.

In one embodiment, information pertaining to a first fault occurring during operation of a virtual machine (VM) is stored in a first field. A second fault is detected while delivering the first fault to the VM, and a determination is made as to whether the second fault is associated with a transition of control to a virtual machine monitor (VMM). If this determination is positive, information pertaining to the second fault is stored in a second field, and control is transitioned to the VMM.

In some embodiments, the invention involves a system to deprivilege components of a virtual machine monitor and enable deprivileged service virtual machines (SVMs) to handle selected trapped events. An embodiment of the invention is a hybrid VMM operating on a platform with hardware virtualization support. The hybrid VMM utilizes features from both hypervisor-based and host-based VMM architectures. In at least one embodiment, the functionality of a traditional VMM is partitioned into a small platform-dependent part called a micro-hypervisor (MH) and one or more platform-independent parts called service virtual machines (SVMs). The micro-hypervisor operates at a higher virtual machine (VM) privilege level than any SVM, while the SVM and other VMs may still have access to any instruction set architecture (ISA) privilege level. Other embodiments are described and claimed.

In one embodiment, an apparatus includes a set of multiplex blocks coupled with an interrupt controller and multiple interrupt request lines, and a virtual machine monitor block (VMM) coupled to the set of multiplex blocks. Each multiplex block corresponds to a distinct interrupt request line. Each multiplex block is to route the interrupt request signal received via the corresponding interrupt request line either to the interrupt controller or the VMM block depending on a current configuration value of this multiplex block.
