Delivery of events from a virtual machine to a thread executable by multiple host CPUs using memory monitoring instructions

摘要

A method and system for managing a virtual computing system including a hypervisor managing a virtual machine (VM) configured to communicate with a thread executable by multiple host central processing units (CPUs), using memory monitoring instructions. The hypervisor provides the virtual machine with a first notification identifying a first designated memory range writeable by a virtual central processing unit (VCPU) associated with the virtual machine and a first instruction to write to the first designated memory range to communicate with the thread running on a first host CPU. The hypervisor further identifies movement of the thread from the first host CPU to a second host CPU and provides to the virtual machine a second notification identifying a second designated memory range and a second instruction to write to the second designated memory range to communicate with the thread running on the second host CPU.
