Description
Technical Field
The invention belongs to the technical field of computers, and particularly relates to a high-availability realization method, device and equipment for a virtual machine.
Background
The virtual machine HA (High Availability ) function refers to a function of providing high availability to an application running on a virtual machine. If the server fails, the affected virtual machine can be restarted on other production servers with redundant capacity, so that the downtime and the service interruption time are effectively reduced.
The HA function allows a virtual machine on a failed virtual host (a physical server on which the virtual software is installed, and the following is the same) to be started on other virtual hosts under the condition of resource permission in a cluster, and the service time interval between the virtual machines is: VM system start time + application start time + heartbeat detection time typically not exceeding 15 seconds, this total interrupt time can typically be kept within 3 minutes.
In the prior art, a common HA operating mechanism is that an agent program placed on each virtualized host continually sends out a "heartbeat signal" to other hosts in the cluster, and once the "heartbeat signal" is terminated, all affected virtual machines will restart on the other hosts. For example, in the most commonly used VMware virtualization software at present, the running state of the virtual machine can be monitored by installing VMtools, and a monitoring signal is sent out by the VMtools, if no signal is received within a specified time, the abnormal state of the virtualization host is indicated, and the virtual machine above will be restarted automatically.

s101, constructing a special synchronous network of a virtual machine cluster, and establishing connection between each virtual machine node in the virtual machine cluster and the special synchronous network;
the special synchronous network is a network special for the virtual machine clusters, each virtual machine cluster is correspondingly provided with a special synchronous network, and the network is isolated from other service networks, management networks, storage networks and the like; based on the special synchronous network, the subsequent state fingerprint information synchronous transmission can be realized.

When the state fingerprint information of a certain virtual machine node is different from the sample state fingerprint information, the state fingerprint information of the virtual machine node is re-synchronized, including but not limited to dormancy, awakening and re-synchronizing operations of the virtual machine node.
