Description
Technical Field
The invention relates to the field of server virtualization, in particular to a method, a device and a system for automatically opening a high-availability function of a virtual machine.
Background
The virtual machine HA (High Availability) function refers to a function of providing High Availability to an application program running on a virtual machine. If a server fails, the affected virtual machines will restart on other production servers with excess capacity, effectively reducing down time and service interruption time.
The HA function allows a virtual machine on a failed virtualized host (physical server with installed virtualization software, the same below) to be started on other virtualized hosts with resource permissions in a cluster, with the business time break between: VM system boot time + application boot time + heartbeat detection time, which typically does not exceed 15 seconds, typically this total interrupt time can be kept within 3 minutes.
The current common HA mechanism of operation is that an agent placed on each virtualized host continually sends a "heartbeat" to the other hosts in the cluster, and once the "heartbeat" is terminated, all affected virtual machines will restart on the other hosts. For example, in the most common VMware virtualization software at present, the running state of the virtual machine may be monitored by installing VMtools, and a monitoring signal is sent by the VMtools, and if no signal is received within a specified time, it indicates that the virtualization host is abnormal, and the above virtual machine will be automatically restarted. There are three options for this specified time, 2 minutes, 1 minute, and 30 seconds.
A relatively common HA starting method for a virtual machine is to start an HA function for a whole server virtualization cluster, where all virtual machines in the cluster have HA function protection, and when a new virtual machine is created, the virtual machine HAs the HA function of the virtual machine. With the rapid development and large-scale application of virtualization technology, the configuration function of the virtual machine HA gradually develops from cluster configuration to a configuration mode that can use a single virtual machine as granularity, that is, the virtual machines in the whole HA cluster are not protected by HA, but the virtual machines needing protection are specified on the management platform, when a virtualization host fails, the virtual machines with the "opened HA" are restarted only on other hosts, and the virtual machines without the HA function being opened are not restarted. Currently, in the actual operation of a cloud service provider, an HA management mode in which a virtual machine is configured with granularity is widely applied.
However, the HA configuration with the virtual machine as granularity generally requires the configuration of the underlying system on the backend platform, or the default configuration during creation, which is not favorable for the user to perform self-service on demand; however, the physical host performs the function configuration of the virtual machine, and system parameters need to be changed, which easily causes system instability and affects other virtual machines on the host system.

6. The cloud management platform of claim 5, wherein the virtual machine migration module comprises an alternative physical machine determination submodule and a virtual machine migration submodule, wherein:
the alternative physical machine determining submodule is used for selecting one of other virtualization hosts which support the HA function and have sufficient redundant resources as an alternative virtualization host;
and the virtual machine migration submodule is used for migrating the virtual machine to the alternative virtualization host.
7. The cloud management platform of claim 5 or 6,
the heartbeat monitoring module is used for informing the virtual machine agent device to report heartbeat information to the cloud management platform when informing the virtual machine agent device to report the heartbeat information; or, the virtual machine agent device is informed to report heartbeat information to the heartbeat monitoring host through the heartbeat network.
8. The virtual machine agent device is characterized in that the virtual machine agent device is positioned in a virtual machine;
the virtual machine agent device comprises an opening request receiving module, an opening application sending module and a heartbeat information reporting module, wherein:
the opening request receiving module is used for receiving a high-availability function opening request of a user;
a provisioning application sending module, configured to send a high-availability function provisioning application to a cloud management platform according to the high-availability function provisioning request, so that the cloud management platform detects whether a virtualization host where the virtual machine is located supports the high-availability function, and under the condition that the virtualization host where the virtual machine is located supports the high-availability function, list the virtual machine in a heartbeat monitoring list, and notify a virtual machine agent device to start to report heartbeat information; under the condition that a virtualization host where the virtual machine is located does not support a high-availability function, the cloud management platform migrates the virtual machine to other virtualization hosts which support HA functions and have sufficient redundant resources, then lists the virtual machine in a heartbeat monitoring list, and informs a virtual machine agent device of the virtual machine to start reporting heartbeat information;
and the heartbeat information reporting module is used for responding to a heartbeat information reporting instruction sent by the cloud management platform and starting to report heartbeat information.
9. An automatic opening system for high-availability functions of a virtual machine, which is characterized by comprising the cloud management platform according to any one of claims 5 to 7 and the virtual machine agent device according to claim 8.
