Embodiment Construction

[0049] like figure 1 , 2 As shown, the mechanism of the present invention includes the following steps:

[0050] Step 1: Configure shared storage on each implementation side to store shared resources such as virtual machine image files and cloud disks;

[0051] Step 2: The user creates a virtual machine and cloud disk in the shared storage on the implementation side, and configures the virtual machine for high availability;

[0052] Step 3: The monitoring module performs real-time monitoring on the implementation end, and sends an alarm once the connection of the implementation end is found to be abnormal;

[0053] Step 4: The monitoring module collects abnormal information and forwards it to the management terminal in time;

[0054] Step 5: The management terminal receives the monitoring abnormal information and performs abnormal analysis: if the analysis result determines that the source implementation terminal is abnormal, the target implementation terminal is selected a...

Abstract

The invention relates to the technical field of cloud computing, in particular to a high availability mechanism for a virtual machine. The high availability mechanism is realized according to the following steps: 1, configuring a shared memory on each realizing end; 2, creating the virtual machine and a cloud disk in the shared memory by a user, and configuring high availability for the virtual machine; 3, acquiring communication information of each realizing end by a monitoring module; 4, collecting abnormal information and timely forwarding the same to a management end by the monitoring module; 5, performing abnormality analysis by the management end, selecting a target realizing end to move and record the virtual machine and the cloud disk thereof if a circumstance that a source realizing end is abnormal is determined, and ignoring the abnormal information if no abnormality exists; 6, when the source realizing end which is abnormal return to normal, automatically connecting with the management end to perform corresponding synchronous processing on the virtual machine thereon. The high availability mechanism guarantees that the virtual machine still can provide services outwards when a host machine to which the virtual machine belongs is in a failure, and can be used on a cloud platform of cloud computing Iaas.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a virtual machine high availability mechanism. Background technique [0002] In cloud computing, virtual machines are widely used to replace physical machines as the carrier of application deployment. Based on the advantages of on-demand use and rapid deployment of virtualization, virtual machines can replace the active and standby redundancy of traditional physical machines by means of dynamic migration. A high-availability implementation method. The so-called dynamic migration refers to the technology that automatically migrates the virtual machine on it to other physical machines when the system detects a failure of the physical machine. The general dynamic migration technology is as follows: [0003] 1. The system detects that the physical machine has a network failure and cannot be connected; [0004] 2. The system selects the target virtual machine for each virtual...
