detailed description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

The embodiment of the invention provides a method for managing the state of a virtual machine. As shown in FIG. 1 , the method includes:

Step 101: Receive a first virtual machine information list reported by the host, where the first virtual machine information list includes IDs and status information of all virtual machines running on the host;

Step 103: When there is a different virtual machine ID in the second virtual machine information list corresponding to the host locally saved in the first virtual machine information list, and locally saved in the second virtual machine information When the different virtual machine IDs and the virtual machine states corresponding to the different virtual machine IDs are queried in the list of other virtual machines other than the list, the virtual machine state is managed according to the query result.

Specifically, when the query result is that the virtual machine state corresponding to the different virtual machine IDs in the other virtual machine list is in a shutdown state, updating the different virtual machines according to the first virtual machine information list. The host and status information corresponding to the ID.

Specifically, when the query result is that the virtual machine state corresponding to the different virtual machine IDs in the other virtual machine list is suspended or suspended or suspended or offline or unknown, an alarm is triggered.

Specifically, when the query result is that the virtual machine state corresponding to the different virtual machine IDs in the other virtual machine list is in an running state, an alarm is triggered.

Specifically, the method further includes discarding information corresponding to the different virtual machine IDs in the first virtual machine information list when the different virtual machine IDs are not queried in the other virtual machine list saved locally.

The following is a detailed description of the example. The virtual management center (VMC) is the execution entity. The virtualized management center VMC stores all the virtual machines that belong to its management in the memory and database. Information, including the ID of each virtual machine, under which host the virtual machine runs, and the current state of the virtual machine. That is, the VMC saves a list of virtual machine information (vmlist) corresponding to all hosts that it manages. The corresponding host periodically reports the virtual machine information list to the virtualization management center, including all the virtual machine information running on the current host, including the virtual machine ID (for example, a Universally Unique Identifier (UUID). After the VMC receives this message, it updates the list of virtual machine information in the memory or database synchronously, including the host under which the virtual machine is running, the current status, and so on.

Specifically, if the VMC determines that the virtual machine UUID in the vmlist reported by the host is the same as the virtual machine UUID in the vmlist of the host saved in the VMC, the VM state in the memory and the database is updated to the latest one, that is, updated to Reported information.

The present invention provides the following optimization examples to solve the above problems.

1. According to the reported vmlist, the loop comparison query is performed in the vmlist saved in the VMC memory. If the query is not found, the virtual machine that is reported is not the virtual machine managed by the VMC, and the VMC does not process the reported virtual machine message. ;

2. If the query is available, the reported virtual machine belongs to the VM managed by the VMC, and the virtual machine is obtained in the VMC save state. The virtual machine state may be that the virtual machine is not on the host or the virtual machine is running or the virtual machine is in a dead state or a virtual machine suspended state or a virtual machine suspended state or a virtual machine offline state or a virtual machine offline state;

3. If the virtual machine is a virtual machine managed by the VMC, and the virtual machine is in a shutdown state, the virtual machine state reported by the host is used to update the running host and status of the virtual machine in the VMC to be reported to the host. The information is consistent;

4. If the virtual machine is a virtual machine managed by the VMC, and the virtual machine state saved on the VMC side is suspended or suspended or suspended or offline or unknown state, the VMC triggers an alarm;

5. If the virtual machine is a virtual machine managed by the VMC, and the virtual machine saved on the VMC side is in a running state (running on another host), it indicates that the virtual machine has multiple problems, and the VMC triggers an alarm.

When the VMC judges that the VM ID existing in the vmlist reported by the host is not found in the vmlist of the host saved in the VMC memory, if the VMC does not perform other control, it is easy to cause in the live network operation. The virtual machine has multiple occurrences, because the VMC side thinks that the virtual machine is in the closed state, and can start normally from the interface, so if the startup is on the current host, the virtual machine fails to start, if it starts on other hosts, it will Causes the virtual machine to double up. Through the alarm mechanism of the present invention, the alarm is sent to the management or operation and maintenance personnel in time, and then the intervention mechanism is used to solve the problem that the virtual machine fails to start or increase.

The following describes a specific application scenario of a method for managing a virtual machine state, as shown in FIG. 2,

1. The host 1 reports the virtual machine information list (virtual machine 1 to virtual machine n) on the host to the virtualization management center vmc every 30 seconds.

2. There is no virtual machine n in the virtual machine information list saved by the virtualization management center vmc. At this time, the virtualization management center vmc thinks that the virtual machine n can be started on the host. If it is started on the host 1, the startup fails. Booting on host 2 causes the virtual machine to restart on multiple hosts.

3. To overcome the above problem, it is necessary to process when the host 1 reports the virtual machine information list. If the virtual machine n is a virtual machine managed by the VMC, and the virtual machine saved on the VMC side is in a shutdown state, the running host and status of the virtual machine in the VMC are determined based on the state of the virtual machine reported by the host 1. The update is consistent with the host reporting information; if the virtual machine is a VM managed by the VMC, and the virtual machine saved on the VMC side is in a running state (running on another host, such as host 2), it indicates that the virtual machine exists. The problem is that the VMC triggers an alarm. The alarm information can be sent to the network management system or the virtual machine management unit, and the alarm information can be received by setting a specific virtual machine management interface.

The goal of the system and method is to synchronize the virtual machine state information reported by the virtualization management center and the host in real time. You can also send alarms to the VM management interface for VMs that are started by multiple hosts to perform related processing. Subsequent processing and the present invention The embodiment is not relevant and will not be described in detail.

The embodiment of the invention further provides a device for managing the state of the virtual machine. As shown in FIG. 3, the device includes:

a receiving module, configured to receive a first virtual machine information list reported by the host, where the first virtual machine information list includes IDs and status information of all virtual machines running on the host;

In the embodiment of the present invention, a virtualization management center is further provided. As shown in FIG. 4, the virtual machine management center includes a database and a processor.

The information of all the virtual machines managed by the virtual machine management center is saved in the database, and the information includes information such as a virtual machine ID, a virtual machine state, and a home host.

The processor is configured to receive a first virtual machine information list reported by the host, where the first virtual machine information list includes IDs and status information of all virtual machines running on the host;

When there is a different virtual machine ID in the second virtual machine information list corresponding to the host locally saved in the first virtual machine information list, and stored locally except the second virtual machine information list When the different virtual machine IDs and the virtual machine states corresponding to the different virtual machine IDs are queried in the other virtual machine list, the virtual machine state is managed according to the query result.

Specifically, the foregoing database may be an in-memory database or other storage device.

Specifically, the foregoing virtualization management center may further include a virtual machine management interface, which is configured to receive an alarm sent by the processor and display it to the operation and maintenance or other management personnel. The subsequent processing of the alarm is not the content of the present invention, and is not described in detail.
