Title:
VIRTUAL NETWORK SYSTEM AND VIRTUAL NETWORK SYSTEM COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/221118
Kind Code:
A1
Abstract:
The purpose of the present invention is to realize easy communications between virtual machines, without relying on a proprietary application running on a virtual machine or a virtual communication device on a hypervisor. To that end, in the present invention a virtual communication device (4b) included in a virtual machine guest (1b) of a transmission source writes communication data if a shared memory (61b) is available, and issues, by a hypervisor call, a notification of the completion of the communication data write. A hypervisor (9) issues an interrupt (X) to a virtual machine guest (1a) of an addressee. A virtual communication device (4a), triggered by the interrupt (X), reads the communication data written to the shared memory (61b), and issues, by a hypervisor call, a notification of the completion of the communication data read. The hypervisor (9) issues an interrupt (Y) to the virtual machine guest (1b) of the transmission source. Triggered by the interrupt (Y), the virtual communication device (4b) detects availability in the shared memory (61b).
