Abstract
A method and a computer system for making a computer achieve high availability. The method includes running a host virtual machine on a host virtual machine container; running a servant virtual machine on the servant virtual machine container; and synchronizing the host virtual machine and the servant virtual machine by using an I/O instruction. The system includes at least two computers including a host computer and a servant computer, each computer including a virtual machine container; a virtual machine running on the virtual machine container; and a communication channel making the virtual machine container execute a virtual machine synchronization operation. The virtual machine synchronization operation of the virtual machine container is triggered by the virtual machine executing I/O instructions.
