Abstract
A hypervisor receives a notification from a source virtual machine that provides network function virtualization (NFV) support to execute a VM function component to send a request to a virtual processor. The VM function component identifies a physical processor associated with the virtual processor, and adds the request to a memory space associated with the physical processor.
Claims20
A method comprising:
- receiving, by a hypervisor executed by a processing device, a notification from a guest operating system of a virtual machine (VM) to execute a VM function, wherein in response to the notification, the VM function is executed to send a request to a virtual processor;
- identifying, by the hypervisor, a physical processor associated with the virtual processor;
- storing, using a VM function component of the hypervisor, the request in a memory space associated with the physical processor;
- and
- responsive to determining, by the VM function component, that polling of the memory space is enabled, completing execution of the VM function without issuing an exit to the hypervisor.

A computing apparatus comprising:
- a memory;
- and
- a processing device, operatively coupled to the memory, to:
- receive, using a hypervisor, a notification from a guest operating system of a virtual machine (VM) to execute a VM function, wherein in response to notification, the VM function is executed to send a request to a virtual processor;
- identify, using the hypervisor, a physical processor associated with the virtual processor;
- store, using a VM function component of the hypervisor, the request in a memory space associated with the physical processor;
- and
- responsive to determining, by the VM function component, that polling of the memory space is enabled, complete execution of the VM function without issuing an exit to the hypervisor.
5 more elements
A non-transitory computer readable storage medium, having instructions stored therein, which when executed by a processing device of a computer system, cause the processing device to:
- receive, using a hypervisor, a notification from a guest operating system of a virtual machine (VM) to execute a VM function, wherein in response to notification, the VM function is executed to send a request to a virtual processor;
- identify, using the hypervisor, a physical processor associated with the virtual processor;
- store, using a VM function component of the hypervisor, the request in a memory space associated with the physical processor;
- and
- responsive to determining, by the VM function component, that polling of the memory space is enabled, complete execution of the VM function without issuing an exit to the hypervisor.
