Mixed Shared/Non-Shared Memory Transport for Virtual Machines

摘要

Methods, systems and computer program products are provided for mixed shared/non-shared memory transport in virtual machines. A computer-implemented method may include providing a shared memory area writeable by a first virtual processor and a second virtual processor that are runnable on a host CPU, retrieving the information stored in the shared memory area by the first virtual processor when the first virtual processor stops running on the host CPU and before the second virtual processor runs on the host CPU, and storing the retrieved information from the shared memory area in a non-shared memory.

1. A computer-implemented method, comprising:
providing, by a hypervisor executing on a host computer, a shared memory area writeable by a first virtual processor and a second virtual processor that are runnable on a host CPU; retrieving, by the hypervisor, information stored in the shared memory area by the first virtual processor after the first virtual processor stops running on the host CPU and before the second virtual processor runs on the host CPU; and storing, by the hypervisor, the information retrieved from the shared memory area in a non-shared memory area.
