Abstract
In an embodiment, a device interrupt manager may be configured to receive an interrupt from a device that is assigned to a guest. The device interrupt manager may be configured to transmit an operation targeted to a memory location in a system memory to record the interrupt for a virtual processor within the guest, wherein the interrupt is to be delivered to the targeted virtual processor. In an embodiment, a virtual machine manager may be configured to detect that an interrupt has been recorded by the device interrupt manager for a virtual processor that is not currently executing. The virtual machine manager may be configured to schedule the virtual processor for execution on a hardware processor, or may prioritize the virtual processor for scheduling, in response to the interrupt.
