Abstract
According to one example, a method includes, with a hypervisor, advertising a paravirtualized cluster mode for a guest using a legacy Advanced Programmable Interrupt Controller (APIC), the paravirtualized cluster mode allowing for interrupts using logical destination mode on a virtual machine having a plurality of virtual cores that is greater than eight. The method further includes, associating each of the plurality of virtual cores with an N-bit identifier formatted to be one of 2different values. The method further includes, with the hypervisor, in response to receiving an interrupt for the virtual machine, determining to which of the plurality of virtual cores the interrupt should be sent based on at least a subset of bits in a destination address of the interrupt.
