Network File System (NFS, Network File System) is a directory sharing mechanism. Different virtual machines that mount the same file directory, through the support of the network file system, can operate the shared partition on the virtual machine like a local partition ( directory) to operate.

In order to solve the above problems, this application provides a virtual machine connection method, which is applied to proxy service equipment. Figure 1 is a schematic flow diagram of a virtual machine connection method provided by an embodiment of this application. As shown in Figure 1, the Said method comprises the following steps at least:

Step S101, obtaining the connection request of the remote desktop protocol of the client;

Here, the proxy service device can be at least one of the following: a gateway (Gateway) and a background service (Backend Service). Here, the gateway can implement the function of proxy connection. In the process of realizing the proxy connection, when the gateway detects that the virtual machine connected by the client is unavailable, it will establish another connection between the virtual machine and the client. In this way, the probability of abnormal access can be reduced. In the process of realizing the background service, the proxy service device can at least realize one of the following functions: detecting the running state of the virtual machine, controlling the virtual machine's power on and off, and modifying the identity of the virtual machine.

Here, the client accesses the virtual machine through the Remote Desktop Protocol (Remote Desktop Protocol, RDP), and displays the remote desktop of the virtual machine on the client.

Here, the first identified virtual machine can be created using a network file system (NFS) disk, and another virtual machine can use the same NFS disk to mount the same file directory, so that the first identified virtual machine The data stored in the virtual machine corresponds to the data stored in the second identified virtual machine.

Step S103, when the connection with the first identified virtual machine is interrupted, obtain the connection information of the second identified virtual machine; wherein, the data stored in the first identified virtual machine is the same as the second identified virtual machine corresponding to the data stored in the virtual machine;

Here, the second identified virtual machine may be a virtual machine of multiple host servers, or may be multiple virtual machines in one host server.

In the event of a virtual machine failure, another virtual machine on one host server can be used to connect to the client. In the event of a host server failure, a virtual machine on another host server can be used to establish a connection to the client.

Here, the connection information may be an Internet Protocol (IP) address of the second identified virtual machine. Here, when the proxy service device senses that the connection with the first-identified virtual machine is interrupted, it queries the connection information of the second-identified virtual machine, establishes a connection with the second-identified virtual machine, and continues to provide services for the client. Here, a remote desktop connection may be established with the first identified virtual machine through a gateway between the client and the proxy service device.

Step S104, based on the connection information, send the connection request to the second identified virtual machine, and establish a connection between the client and the second identified virtual machine, so that the client By accessing the data stored in the second identified virtual machine, the remote desktop of the first identified virtual machine is displayed.

In this way, when the client connects to the virtual machine, it does not connect directly, but connects through a proxy service device. When the proxy service device perceives that the first identified virtual machine is faulty or the network is unavailable, it establishes a connection with the second identified virtual machine to replace the first identified virtual machine, so that the proxy service device replaces the connection with the virtual machine, but keeps Open the connection with the client, so that the client is not aware of the switching of the virtual machine.

The present application provides a method for connecting a virtual machine, which is applied to a proxy service device. FIG. 2 is a schematic flowchart of a method for connecting a virtual machine provided in an embodiment of the present application. As shown in FIG. 2 , the method at least includes the following step:

Step S201, obtaining the connection request of the remote desktop protocol of the client;

Step S202, sending the connection request to the first identified virtual machine, establishing a connection between the client and the first identified virtual machine, so as to display the first identified virtual machine through the client machine's remote desktop;

Step S203, when the connection with the first identified virtual machine is interrupted, obtain the connection information of the second identified virtual machine; wherein, the data stored in the first identified virtual machine is the same as the second identified virtual machine corresponding to the data stored in the virtual machine;

In a practicable manner, the host server where the first identified virtual machine resides is different from the host server where the second identified virtual machine resides;

The first identified virtual machine and the second identified virtual machine mount the same file directory through the network file system, so that the data stored in the first identified virtual machine and the second identified virtual machine corresponding to the data stored in the machine.

Here, the second identified virtual machine may be: created on another host server using the same image as the first identified virtual machine. Here, the second identified virtual machine mounts the NFS disk of the first identified virtual machine. Here, after the creation is successful, the second-identified virtual machine is placed in a dormant state to save resources. Here, the host server may be a data center for storing data.

Here, the second-identified virtual machine does not occupy CPU and memory resources when it is in a dormant state, and only creates a memory image on the disk. For example, based on a 10% failure rate calculation, a host server with 8 cores and 16G memory can back up 20 virtual machines with 4 cores and 8G memory. 160G of disk space is required during backup.

In the foregoing embodiment, on the one hand, the host server where the first identified virtual machine resides is different from the host server where the second identified virtual machine resides. In this way, the failure of the host server of the first-identified virtual machine will not affect the second-identified virtual machine, and the virtual machine can continue to be used without waiting for the recovery of the failure of the host server where the first-identified virtual machine is located. On the other hand, the first identified virtual machine and the second identified virtual machine mount the same file directory through the network file system, so that the data stored in the first identified virtual machine is the same as the second identified virtual machine Corresponds to the data stored in the two identified virtual machines. so. Mount the same file directory through the network file system to ensure data consistency.

Step S204, based on the connection information, send the connection request to the second identified virtual machine, and establish a connection between the client and the second identified virtual machine, so that the client By accessing the data stored in the second identified virtual machine, the remote desktop of the first identified virtual machine is displayed.

Here, the applying the input-output event flow to the second identified virtual machine includes: forwarding the input-output event flow to the host server of the second identified virtual machine, so as to pass the second identified virtual machine The host server of the second identified virtual machine applies the input and output event stream to the second identified virtual machine, so that the data stored in the first identified virtual machine is different from the data stored in the second identified virtual machine data are the same.

In a practicable manner, in the step S202, after the connection between the client and the first identified virtual machine is established, the method further includes: detecting the The running state of the virtual machine identified by the first identification; when it is detected that the operating state of the virtual machine identified by the first identification is abnormal, it is determined that the connection with the virtual machine identified by the first identification is interrupted.

In the above embodiment, on the one hand, the input and output event flow of the first identified virtual machine is acquired; the input and output event flow is applied to the second identified virtual machine, so that the first identified virtual machine The data stored in the virtual machine corresponds to the data stored in the second identified virtual machine. In this way, data between different virtual machines can be synchronized in real time, improving data consistency. On the other hand, detecting the running state of the first identified virtual machine according to a preset duration; Connection lost. In this way, by periodically detecting the running state of the first identified virtual machine, it is possible to timely determine the connection interruption problem caused by the abnormality of the virtual machine.

The present application provides a method for connecting a virtual machine, which is applied to a proxy service device. FIG. 3 is a schematic flowchart of a method for connecting a virtual machine provided in an embodiment of the present application. As shown in FIG. 3 , the method at least includes the following step:

Step S301, obtaining the connection request of the remote desktop protocol of the client;

Step S302, sending the connection request to the first identified virtual machine, establishing a connection between the client and the first identified virtual machine, so as to display the first identified virtual machine through the client machine's remote desktop;

Step S303, when the connection with the virtual machine with the first identification is interrupted, control the virtual machine with the second identification to start up, obtain the connection information of the virtual machine with the second identification, and set the identification of the virtual machine to Change from the second identification to the first identification, so that when the connection request of the remote desktop protocol of the client is obtained again, the connection request is sent to the virtual machine with the modified identification of the first identification; wherein, the first The data stored in the identified virtual machine corresponds to the data stored in the second identified virtual machine;

Step S304, based on the connection information, send the connection request to the second identified virtual machine, and establish a connection between the client and the second identified virtual machine, so that the client By accessing the data stored in the second identified virtual machine, the remote desktop of the first identified virtual machine is displayed.

In a practicable manner, the method further includes: acquiring connection information of the virtual machine whose identity is changed from the second identity to the first identity; based on the connection information, sending the connection request to the virtual machine from the second The identification is changed to the virtual machine with the first identification, and a connection between the client and the virtual machine with the first identification is established, so as to display the remote desktop of the virtual machine with the first identification through the client.

Here, the identifier of the virtual machine may be changed from the second identifier to the first identifier, so as to establish a connection with the virtual machine with the first identifier. By modifying the identity of the virtual machine, in the process of establishing a connection between the client and the virtual machine, the virtual machine that is first connected to the client, in the case of an abnormal running state of the virtual machine, uses another virtual machine as the first to connect to the client virtual machine.

In a practicable manner, when the connection request is sent to the virtual machine whose identity is changed from the second identity to the virtual machine with the first identity, the connection between the client and the virtual machine with the first identity is established Afterwards, the method further includes: acquiring the input input of the virtual machine modified from the second identifier to the first identifier

output event flow; when it is detected that the virtual machine with an abnormal running state returns to normal, change the identification of the virtual machine from the first identification to the second identification, and apply the input and output event flow to the In the virtual machine modified from the first identification to the second identification; the virtual machine modified from the first identification to the second identification

The operating state of the virtual machine is changed from the power-on state to the dormant state, so that when the connection with the virtual machine whose identity is changed from the second identity to the 0th first identity is interrupted, the client and the virtual machine whose identity is changed from the first identity are established. for the connection between the virtual machines identified by the second.

Here, the second identified virtual machine sends the memory input and output event stream to the proxy service device. When the proxy service device senses that the virtual machine with the first identification is restored, it changes the identification of the virtual machine with the first identification to

For the second identification, apply the I/O event flow sent by the virtual machine of the second identification during the failure period, and then make the virtual machine of the fifth identification dormant.

In the above embodiment, the running state of the virtual machine whose identity is changed from the first identity to the second identity is changed from the power-on state to the dormant state, so as to connect to the virtual machine whose identity is changed from the second identity to the first identity. In case of interruption, establish the client and the virtual ID modified from the first ID to the second ID

connection between machines. In this way, when the virtual machine is in a dormant state, only hard disk resources are occupied, and the cost is controllable. In addition, the virtual machine with the second identification can be powered on from the dormant state for a short time, and the proxy service device automatically switches to the virtual machine with the second identification, and no fault can be sensed during use.

Realize remote desktop by establishing a virtual machine on the host server. The stability of the virtual machine depends on the stability of the host server. When the host server fails, the remote desktop of the virtual machine is unavailable. It is possible to restore the connection of the remote desktop by regularly making snapshots for the virtual machine, and applying the snapshot to restore the data in the virtual machine after the host server recovers. However, the above method needs to wait for the host server to resume operation. In the case of a host server failure, the virtual machine is unavailable; and, when making a snapshot for the virtual machine, the data of the virtual machine after the snapshot creation time point will be lost, and remote desktop failures will occur. The problem.

In order to solve the above problems, the present application provides a method for connecting a virtual machine. FIG. 4 is a schematic flowchart of a method for connecting a virtual machine provided in an embodiment of the present application. As shown in FIG. 4 , the method includes at least the following steps :

Step S401, creating a first identified virtual machine 41.

Here, the first identified virtual machine is created using a Network File System (NFS) 45 disk.

Step S402, creating a second identified virtual machine 42.

Here, the second identified virtual machine may be: created on another host server using the same image as the first identified virtual machine. Here, the second identified virtual machine mounts the NFS disk of the first identified virtual machine. Here, after the creation is successful, the second-identified virtual machine is placed in a dormant state to save resources. Here, the host server may be a data center.

Step S403 , the first identified virtual machine 41 sends the input/output event stream to the proxy service device 43 .

Here, the step S403 may be performed when the first identified virtual machine is in a power-on state. Here, the input and output event stream may be an event stream stored in memory. Here, the proxy service device can include: gateway 431 (Gateway)+backend service 432 (Backend Service), the proxy service device can realize the proxy function of the gateway and/or the function of the background service.

Step S404, the proxy service device 43 forwards the I/O event stream to the host server where the second identified virtual machine 42 is located; the host server where the second identified virtual machine is located applies the input/output event stream to the second identified virtual machine.

In step S405, the proxy service device periodically detects the health status of the first-identified virtual machine, and when it senses that the first-identified virtual machine is unavailable, starts the second-identified virtual machine and changes it to the first-identified virtual machine.

Here, periodically detecting the health status of the first identified virtual machine may be implemented through a background service in the proxy service device.

Step S406 , the client 44 establishes a remote desktop connection with the first identified virtual machine 41 through the proxy service device 43 . When the proxy service device 43 perceives that the connection with the virtual machine 41 of the first identification is interrupted, it queries the connection information of the virtual machine 42 of the second identification, establishes a connection with the virtual machine 42 of the second identification, and continues to provide services for the client 44 .

Here, a remote desktop connection may be established with the first identified virtual machine through the gateway 431 of the client and proxy service device. Here, the connection information may be an Internet Protocol (IP) address of the second identified virtual machine.

Step S407, the second identified virtual machine sends the memory input and output event stream to the proxy service device. When the proxy service device perceives that the virtual machine with the first identification is restored, it changes the identification of the virtual machine with the first identification to the second identification, applies the input and output event flow sent by the virtual machine with the second identification during the failure period, and then lets the first identification The virtual machine hibernates.

Here, the second-identified virtual machine does not occupy CPU and memory resources when it is in a dormant state, and only creates a memory image on the disk. For example, based on a 10% failure rate calculation, a host server with 8 cores and 16G memory can back up 20 virtual machines with 4 cores and 8G memory. 160G of disk space is required during backup.

In the above-mentioned embodiment, on the one hand, the second-identified virtual machine is created, which is created on another host server using the same image as the first-identified virtual machine, and the second-identified virtual machine mounts the first The NFS disk of the identified virtual machine. In this way, the same disk is mounted through nfs to ensure that the disk data is consistent. The second-identified virtual machine can synchronize the memory data of the first-identified virtual machine to the second-identified virtual machine in real time, and the memory is synchronized using real-time data streams, which prevents users from losing data. In addition, the virtual machine with the first identification and the second identification are not in the same host server, the failure of the host server of the virtual machine with the first identification will not affect the virtual machine with the second identification, and there is no need to wait for the host server where the virtual machine with the first identification is located. Server failure recovery can continue to use.

On the other hand, the client establishes a remote desktop connection with the first identified virtual machine through the proxy service device. In this way, when connecting to the virtual machine, the virtual machine is not directly connected, but is connected through a proxy service device. When the proxy service device perceives that the first identified virtual machine is faulty or the network is unavailable, it establishes a connection with the second identified virtual machine to replace the first identified virtual machine, so that the proxy service device replaces the connection with the virtual machine, but keeps Open the connection with the client, so that the client is not aware of the switching of the virtual machine.

On the other hand, the virtual machine with the second identifier can be turned on from the dormant state for a short time, and the proxy service device automatically switches to the virtual machine with the second identifier, and no fault is detected during use. In addition, the virtual machine of the second identification only occupies hard disk resources in a dormant state, and the cost is controllable.
