Inter-process communication method and device and computer readable medium

The invention discloses an inter-process communication method and device and a computer readable medium. The method comprises the steps that a host machine writes an activation mark into a target bitcorresponding to a target client in a bitmap; wherein the target client is a to-be-notified client of the host machine in a virtual machine, and the target bit is used for indicating that the target client is the to-be-notified client or indicating that the target client is not the to-be-notified client; the host machine writes an interrupt command into an interrupt register; wherein the interruptregister is a register shared by the virtual machine and the host machine, the interrupt command comprises an interrupt number, and the interrupt command is used for indicating a client correspondingto the combination of the interrupt number and the target bit to receive a message from a message receiving queue. In the embodiment of the invention, the to-be-notified client is indicated through the combination of the inter
