Fig. 1 is a schematic flow chart of a virtual machine management method provided by the present invention, where the method of the present invention is applicable to a scenario of improving reliability of a virtual machine management platform, and the method may be performed by a virtual machine management device provided by the present invention and applied to a client, and the device may be implemented in a software and/or hardware manner. In a specific embodiment, the apparatus may be integrated in an electronic device, such as a server comprising a virtual machine management system. The following embodiments will take the example that the apparatus is integrated in a virtual machine management system, and referring to fig. 1, the method may specifically include the following steps:
step 101, sending state data to a console management network through a host management network, or sending state data to a console service network through a host service network.
The host node refers to a physical server that carries a virtual machine in a virtualized environment. Virtualization software may be run on the host node for managing and allocating computing resources of the host to the virtual machines. In the virtual machine management platform, a user can view and manage host machine nodes through a host machine node management interface, and the operations of monitoring the resource use condition of a host machine, configuring the network and storage setting of the host machine, maintaining and upgrading the host machine and the like are included. The virtual machine management system comprises a console and a host machine node, wherein the console is a user interface of the virtual machine management platform and is used for managing and operating the virtual machine. Through the console, an administrator can create, configure, deploy, and monitor virtual machines, as well as manage the resources of host nodes. Thus, the console needs to determine whether the host node is available, where the host node is available, to provide the user with the functionality to manage and operate the virtual machine.
Specifically, the host nodes include a host traffic network, a host management network, and a host storage network. The console comprises a console service network, a console management network and a console storage network. The host management network is in communication connection with the console management network, and the console can receive the state data of the host sent by the host management network through the console management network. In an alternative embodiment, when the console management network does not receive the status data sent by the host management network, the step of sending the status data to the console management network of the console through the host management network of the host node is repeatedly executed until the number of times the console management network receives the status data or the host management network sends the status data reaches a preset number of times; if the number of times of sending the state data by the host management network reaches the preset number of times and the state data is not received by the console management network, sending the state data to the console service network through the host service network.
Step 102, determining, by the console, whether the host node is available based on the status data.
The state data of the host include the running state, the resource utilization rate, the number of virtual machines, the network connection state, the health state and the like of the host. The running state indicates whether the host node is running normally, and the host node generally includes running states such as running, shutdown, pause and maintenance. The resource utilization represents the use condition of the computing resource of the host node, including the utilization of a central processing unit (Central Processing Unit, CPU), the utilization of a memory, the utilization of a disk space, and the like. The number of virtual machines includes the number of virtual machines running on the host node, i.e., the number of virtual machines currently carried by the host node. Network connection status refers to the connection between a host node and other network devices (e.g., switches, routers). The health status indicates whether the overall operation condition of the host node is normal, including whether the hardware health status of the host node, the virtualization software is operating normally, and the like.
Specifically, after receiving the state data of the host node, the console determines whether the host node is available according to each item of data in the state data. For example, when the operational state in the state data is paused, then it may be determined that the host node is not available. And when the number of the virtual machines in the state data exceeds the preset number, indicating that the host node is not available.
Step 103, when the host node is available, managing the virtual machine of the host node.
Wherein the host node includes one or more virtual machines thereon, and the console can manage the virtual machines of the host node when the host node is available. Through the console, an administrator can create, configure, deploy, and monitor virtual machines, as well as manage the resources of host nodes. In this embodiment, optionally, when the host node is available, managing the virtual machine of the host node includes: when the host node is available, receiving virtual machine life cycle data sent by the host node; and carrying out life cycle management on the virtual machine based on the life cycle data.
Wherein, the life cycle data of the virtual machine comprises: virtual machine state, resource utilization, runtime, log and event, virtual machine configuration, etc. The virtual machine state includes an operation state, a health state, and the like of the virtual machine. The resource utilization rate includes CPU utilization rate, memory utilization rate, disk space utilization rate, and the like. The running time comprises the starting time and the running time of the virtual machine. The log and event includes an operational record of the virtual machine, error information, warnings, and the like. The virtual machine configuration includes hardware configuration of the virtual machine, network configuration, storage volume, and the like.
Specifically, when the host node is available, the console may perform lifecycle management on the virtual machine according to lifecycle data of the virtual machine, including: creating and configuring a virtual machine: the console may communicate with the host node through the console management network, create a new virtual machine, and configure the hardware resources of the virtual machine. Starting and stopping the virtual machine: the console may send instructions to the host node through the console management network to start or stop the virtual machine, thereby controlling the operating state of the virtual machine. Migrating the virtual machine: through the console management network, the console can communicate with the host node to migrate the virtual machine from one node to another to achieve load balancing or failure recovery. Monitoring a virtual machine: the control console can acquire monitoring data of the virtual machine on the host machine node through the control console management network, including resource utilization rate, running state and the like, so that an administrator can discover and solve the problems in time. Managing virtual machine snapshots: the snapshot of the virtual machine is managed through the console management network, including operations such as creation, recovery, deletion, and the like.
Through the steps, the virtual machine can be managed and monitored, and a user is helped to easily create, configure, deploy and monitor the virtual machine.
According to the technical scheme of the embodiment, the host management network is used for sending the state data to the console management network, or the host service network is used for sending the state data to the console service network; judging whether the host node is available or not based on the state data through the control console; when the host node is available, virtual machines of the host node are managed. According to the technical scheme, the host node state can be transmitted to the control console through the management network or the service network of the host node, and the reliability of the virtual machine management platform is improved on the basis that no additional equipment is added.
Fig. 2 is a second flow chart of a virtual machine management method according to the present invention, and a specific method may be shown in fig. 2, where the method may include the following steps:
step 201, sending status data to the console management network through the host management network, and when the console management network does not receive the status data sent by the host management network, repeating the step of sending the status data to the console management network of the console through the host management network of the host node until the console management network receives the status data or the number of times of sending the status data by the host management network reaches a preset number of times.
The state data comprises the running state of the host, the resource utilization rate, the number of virtual machines, the network connection state, the health state and the like. The virtual machine management system comprises a control console and a host machine node, wherein the control console comprises a control console management network, a control console service network and a control console storage network. The host nodes comprise a host management network, a host service network and a host storage network. The control console management network is used for managing the life cycle of the virtual machine on the host machine node, receiving state data reported by the host machine node and the like, and the control console service network and the host machine service network are used for supporting service communication between the virtual machines, performing operations such as migration of the virtual machine after the management network is failed, reporting state data reported by the host machine node after the management network is failed and the like.
In the scheme, the control console judges the availability of the host node through the state data sent by the host node. When the host node transmits the state data, the state data is preferentially transmitted through the host management network. If the state data transmission through the host management network fails, the host node transmits the state data again through the host management network until the state data transmission is successful (the state data is received by the console management network) or the transmission times reach the preset times, and the transmission is stopped. Meanwhile, the system determines abnormal communication between the host management network and the console management network.
Step 202, if the console management network receives the status data when the number of times the host management network transmits the status data does not reach the preset number of times, determining the availability of the host node based on the status data.
And 203, if the number of times of sending the state data by the host management network reaches the preset number of times and the state data is not received by the console management network, sending the state data to the console service network through the host service network.
In particular, in the network configuration of the host node, a default gateway is configured on the host management network, and the host service network and the host storage network are not configured with the default gateway, so that when external network communication is performed, the service network of the access control console is in communication with the same network segment, and therefore the default gateway is not required to be passed. Further, in the case of a failure of the host management network (the number of times the host management network transmits the status data reaches a preset number of times and the console management network does not receive the status data), the host node may access the console service network through the host service network, so as to ensure normal communication between the host node and the console.
Further, when normal communication between the host management network and the console management network is not possible (the console management network cannot receive the state data of the host node sent by the host management network), communication is performed between the host node and the console by using the host service network and the console service network through a two-layer MAC (MandatoryAccess Control) mechanism. The communication process comprises the following steps: 1. and (3) frame encapsulation: when the console needs to send data to the host node, the console encapsulates the data into ethernet frames. The frame contains the MAC address of the console as the source MAC address and the MAC address of the host node as the destination MAC address. Mac address table: in the service network where the host node is located, the switch maintains a MAC address table that records the MAC addresses of devices directly connected to the switch. The switch learns the MAC addresses of different devices by monitoring the data frames on the network and adds the MAC addresses to the MAC address table. Mac address learning: when the switch receives a frame from the console, it checks the destination MAC address in the frame. If the destination MAC address already exists in the MAC address table, the switch will send the frame to the correct port based on the information in the table, thereby delivering the data frame to the host. 4. Broadcast and flooding: if the destination MAC address does not exist in the MAC address table, the switch will broadcast the frame to all ports (except the port that received the frame). Thus, the frame is sent to the host node and received by other devices. Mac address table update: when the switch receives a frame from the host node, it also updates the MAC address table. If the source MAC address in the frame does not exist in the table, the switch will add the address to the table and associate with the port that received the frame.
And 204, when the console service network does not receive the state data sent by the host service network, repeating the step of sending the state data to the console service network of the console through the host service network of the host node until the console service network receives the state data or the number of times of sending the state data by the host service network reaches a preset number of times.
Step 205, if the console service network receives the status data when the number of times the host service network transmits the status data does not reach the preset number of times, the availability of the host node is determined based on the status data.
Specifically, when communication between the console management network and the host management network is abnormal, the host node may send status data to the console service network through the host service network. When the console service network does not receive the state data sent by the host service network, the host service network will send the state data of the host to the console service network again until the sending is successful (the console service network receives the state data) or the number of times of sending the state data by the host service network reaches the preset number of times.
And 206, if the number of times the host service network transmits the state data reaches the preset number of times and the console service network does not receive the state data, determining that the host node is unavailable.
If the host service network sends the state data of the host node to the console service network for a plurality of times, but the console service network still does not receive the state data sent by the host service network, the host management network and the host service network can be determined to be faulty, and the host node is further determined to be unavailable.
Step 207, when the host node is available, managing the virtual machine of the host node.
In this embodiment, the state data is sent to the console management network through the host management network, and when the console management network does not receive the state data sent by the host management network, the step of sending the state data to the console management network of the console through the host management network of the host node is repeatedly executed until the console management network receives the state data or the number of times of sending the state data by the host management network reaches a preset number of times. If the number of times of sending the state data by the host management network reaches the preset number of times and the state data is not received by the console management network, sending the state data to the console service network through the host service network. When the console service network does not receive the state data sent by the host service network, repeating the step of sending the state data to the console service network of the console through the host service network of the host node until the console service network receives the state data or the number of times of sending the state data by the host service network reaches a preset number of times; if the number of times of sending the state data by the host machine service network reaches the preset number of times and the console service network does not receive the state data, determining that the host machine node is unavailable. And judging whether the host node is available or not based on the state data through the control console. When the host node is available, virtual machines of the host node are managed. According to the technical scheme, the state data can be sent preferentially through the host management network, when the communication between the host management network and the console management network is failed, the state data is sent to the console service network through the host service network, and the reliability of the virtual machine management platform is improved on the basis that no additional equipment is added.
Fig. 3 is a first schematic structural diagram of a virtual machine management system according to the present invention, as shown in fig. 3, where the system includes: the host node comprises a host machine service network, a host machine management network and a host machine storage network, and the console comprises a console service network, a console management network and a console storage network; the control console is used for receiving the state data sent by the host computer node; judging whether the host node is available or not based on the state data; when the host node is available, managing the virtual machine of the host node; the host machine node is used for sending the state data to the console management network through the host machine management network; or, sending the state data to the console service network through the host service network.
Specifically, the host management network is in communication connection with the console management network, and the console can receive the state data of the host sent by the host management network through the console management network. In an alternative embodiment, when the console management network does not receive the status data sent by the host management network, the step of sending the status data to the console management network of the console through the host management network of the host node is repeatedly executed until the number of times the console management network receives the status data or the host management network sends the status data reaches a preset number of times; if the number of times of sending the state data by the host management network reaches the preset number of times and the state data is not received by the console management network, sending the state data to the console service network through the host service network.
Fig. 4 is a schematic diagram illustrating a host node sending status data to a console according to the present invention. As shown in fig. 4, after collecting the status data, the host node sends the status data to the console management network through the host management network. If the transmission fails, the host management network can send the state data to the console management network again, and if the transmission still fails, the host node can send the state data to the console service network through the host service network. If the transmission fails, the host service network can send the status data to the console service network again, and if the transmission still fails, the host node is considered to be unavailable.
In the scheme, the host management network and the control console management network are both configured with default gateways, and the control console service network and the host service network are connected through the same network segment communication.
In particular, the default gateway for the console and host is a router or switch that is located between the console management network and the console service network. When the console sends a packet to the default gateway, the gateway will examine the network segment to which the target internet protocol (Internet Protocol, IP) address belongs and forward the packet to the host management network.
In the scheme, the console service network and the host service network are in communication connection through the same network segment, and can communicate directly through a two-layer MAC mechanism without routing forwarding through a default gateway. In this case, the console and the host are both in the same network segment, and the communication between them does not need to be IP routed. The console may send data frames directly to the host, and the host may receive and respond to the data frames directly. Illustratively, the communication process includes: the console transmits a data frame: when the console needs to send data to the host, it constructs a data frame containing the console's MAC address as the source MAC address and the host node's MAC address as the destination MAC address. Data frame transmission: the console transmits the data frames over the network to the host service network. The host node receives the data frame: when the data frame arrives at the host service network, the host node checks whether the destination MAC address matches its own MAC address. If so, the host may receive and process the data frame. The host node responds to the data frame: the host node may generate a response data frame as needed and send it back to the console.
In the scheme, the host management network, the host service network, the console management network and the console management network are all provided with double network cards.
The dual network card can be configured by binding a plurality of physical network interfaces together to form a virtual interface. For example, the dual network card bond technology can improve the bandwidth and redundancy of the network and enhance the availability and reliability of the network. Fig. 5 is a second schematic structural diagram of the virtual machine management system provided by the present invention. As shown in fig. 5, the console management network of the console adopts a form of dual network card bond, including a console management network card 1 and a console management network card 2. The console service network of the console adopts a double network card bond form and comprises a console service network card 1 and a console service network card 2. The host management network of the host node adopts a form of double network card bond and comprises a host management network card 1 and a host management network card 2. The host machine business network of the host machine node adopts a double network card bond form and comprises a host machine business network card 1 and a host machine business network card 2.
Specifically, the dual network card bond binds a plurality of physical network cards into a virtual interface, creating a bond interface. The bond interface will have a virtual MAC address and IP address as an identification of the entire interface. The data packets may be sent and received over the bond interface. When one physical network card fails, the other network card can take over the work of the network card, so that the connectivity and the availability of the network are ensured. Meanwhile, the double network card bond can distribute the data packets to different physical network cards according to the configured load balancing strategy, so that the balanced distribution of network traffic is realized, and the network performance and throughput are improved. The bandwidth, redundancy and reliability of the network can be improved through the configuration of the double network card bond.
The system provided in this embodiment includes: the host node comprises a host machine service network, a host machine management network and a host machine storage network, and the console comprises a console service network, a console management network and a console storage network; the control console is used for receiving the state data sent by the host computer node; judging whether the host node is available or not based on the state data; when the host node is available, managing the virtual machine of the host node; the host machine node is used for sending the state data to the console management network through the host machine management network; or, sending the state data to the console service network through the host service network. The system of the embodiment can send the state data preferentially through the host management network, when the communication between the host management network and the console management network has faults, the state data is sent to the console service network through the host service network, and each service network and each management network adopt double network card bond configuration, so that the reliability of the virtual machine management platform is improved on the basis of not adding extra equipment.
