In the scenario of card-based micro-server MOC virtualization technology, an instance actually runs on a real physical machine, and the CPU and memory of the physical machine are all used by the instance.

Therefore, in the case that the user needs to migrate an instance, the most straightforward approach is for the user to stop service, stop the machine, and then assign the system disk to another higher-specification physical machine to create an instance start. That is, a customer downtime is required during the migration of the instance, resulting in an inflexible process of migrating the instance.

In the above-described operating environment, the present application provides an example thermomigration method as shown in FIG. 2. Fig. 2 is a flowchart of an example thermomigration method according to embodiment 1 of the present invention, and the method shown in fig. 2 may include the steps of:
in step S21, the information to be synchronized from the source MOC card is forwarded by the micro server MOC card on the target card, wherein the information to be synchronized is associated with the source instance running on the source machine.
It should be noted that the micro server MOC card on the target card is the target MOC card.
In the step S21, the MOC card is a physical board card device with a CPU and a ROM/RAM, the target MOC card is a target physical board card device, the machine corresponding to the target MOC card is a target machine, and the target machine runs a target instance; the source MOC card is the source physical board card equipment, and the machine corresponding to the source MOC card is the source machine, and the source instance is operated on the source machine.
Alternatively, the information to be synchronized may include memory data of the source instance. A source instance running on a source machine is an instance that needs to be migrated from the source machine to a target machine, and the target MOC card may forward memory data on the source MOC card to the target machine.
The target MOC card is used for receiving the information to be synchronized sent by the source MOC card and forwarding the information to be synchronized to the target machine; and the source MOC card is used for acquiring the information to be synchronized from the source machine and forwarding the information with the synchronization to the target MOC card.
In step S21, the number of cores of the CPU of the target machine is greater than the number of cores of the source machine, and the memory space of the target machine is greater than the memory space of the source machine. Therefore, the specification of the target machine is larger than that of the source machine, the target machine meets the running condition of the source instance, and the source instance can be ensured to be smoothly migrated.
It should be noted that the target machine is consistent with the source machine in CPU model number and consistent in architecture; the memory model of the target machine is consistent with that of the source machine.
In the above embodiment, the target MOC card is required to forward the information to be synchronized from the source MOC card, and therefore, a communication connection between the MOC card and the source MOC card needs to be established before forwarding the information to be synchronized.
In an alternative embodiment provided in the present application, as shown in fig. 3, before forwarding, in step S21, information to be synchronized from a source MOC card through a target MOC card, the method further includes the following steps:
Step S25, establishing communication with the source work process running in the source MOC card through the target work process running in the target MOC card.
It should be noted here that, since the MOC card is a physical device with its own CPU and ROM/RAM, the MOC card itself has the capability of running an operating system MOC OS, and the physical resources of the MOC card are managed by the operating system MOC OS to control the behavior on the MOC card.
Optionally, the operating system running on the target MOC card is a target operating system (i.e., a target MOC OS), and the operating system running on the source MOC card is a source operating system (i.e., a source MOC OS).
It should be noted that, in addition to the operating system MOC OS, an engineering process worker OS is also running on the MOC card, and some auxiliary tasks are implemented by the engineering process worker OS.
Optionally, a target work process (i.e., a target worker OS) is running on the target MOC card, a source work process (i.e., a source worker OS) is running on the source MOC card, and by communicating between the target work process and the source work process, information to be synchronized associated with the source instance running on the source machine is enabled to be sent through the source work process running on the source MOC card, and information to be synchronized of the source MOC card is received through the target work process running on the target MOC card.
Optionally, in the above embodiment, the communication connection between the target MOC card and the target machine may be established through a system bus, so after receiving the information to be synchronized of the source MOC card, the target work process running on the target MOC card may configure the target machine according to the information to be synchronized through the target work process.
Alternatively, the information to be synchronized of the source MOC card may be memory data of the source MOC card.
In an alternative embodiment provided in the present application, as shown in fig. 4, forwarding, by the target MOC card, information to be synchronized from the source MOC card includes:
step S211: receiving memory data from a source work process through a target work process;
step S213: and forwarding the memory data received by the target work process to the target machine through a system bus between the target MOC card and the target machine.
In the above steps S211 and S213, since the target working process running in the target MOC card and the source working process running in the source MOC card may communicate with each other, the memory data of the source MOC card sent by the source working process may be received by the target working process, and then the target working process may forward the received memory data to the target machine through the system bus connected between the target MOC card and the target machine, so that the memory data may be written in the memory of the target machine, thereby implementing migration of the memory data on the source machine, and synchronizing the memory data of the target machine with the memory data of the source machine.
It should be noted that, in the process that the target working process receives the memory data from the source working process, a certain time is required to be consumed for transmitting the memory data, so that the source operating system in the source machine can also normally operate while the source machine transmits the memory data through the source working process, so that the memory data of the source machine can generate new memory information, and then the newly generated content data can be transmitted again after the current transmission of the memory data is completed between the target working process and the source working process.
It should be noted that, in the process of transferring the memory data, the data amount of the newly generated memory data is far smaller than the data amount being transferred, so that the memory data transferred between the target working process and the source working process will be gradually reduced, so that the memory data between the target machine and the source machine presents a synchronous convergence state.
In an alternative embodiment provided in the present application, as shown in fig. 5, forwarding, in step S21, information to be synchronized from a source MOC card through a target MOC card includes:
step S215: when the synchronous convergence degree of the memory data between the target machine and the source machine meets a preset condition, receiving CPU data and controller data from the source work process through the target work process;
Step S217: the CPU data and controller data received by the target work process are forwarded to the target machine via the system bus.
In the above steps S215 and S217, the degree of memory data synchronization between the target machine and the source machine will gradually increase, and in the case where the synchronization of the memory data is achieved between the target machine and the source machine, that is, the degree of synchronization meets the predetermined condition, the CPU data and the controller data from the source work process may be received by the target work process, and the received CPU data and controller data may be forwarded to the target machine through the system bus, so that the target machine may configure the CPU and the controller of the target machine according to the received CPU data and controller data, and the CPU state of the target machine may be synchronized with the CPU state of the source machine, and the controller state of the target machine may be synchronized with the controller state of the source machine.
Here, in the above step S215 and step S217, the controller may include a PCI bus controller, a hardware clock controller, an interrupt controller, and the like on the machine.
In an optional embodiment provided in the present application, after forwarding, by the target MOC card, information to be synchronized from the source MOC card, the method further includes: and when the memory data, the CPU data and the controller data are all synchronously completed, receiving the component information from the source work process through the target work process, wherein the component information is used for transferring the input/output IO request initiated by the target machine in the target MOC card.
In the above embodiment of the present invention, when the memory data, the CPU data, and the controller data in the target MOC card and the source MOC card are all completed synchronously, the target working process will receive the component information from the source working process, and transfer the input/output IO request initiated by the target machine through the component information.
Step S23 starts a target operating system in the target machine, and synchronizes information to be synchronized to the target machine so as to complete the thermal migration of the source instance to the target instance running on the target machine.
It should be noted that, the instance running on the source machine is a source instance, the instance running on the target machine is a target instance, and the information to be synchronized associated with the source instance is forwarded from the source machine to the target machine through the target MOC card and the source MOC card, so that the target machine can realize synchronization of the target machine and the source machine according to the information to be synchronized, thereby completing the thermal migration of the source instance to the target instance running on the target machine.
It should be noted that, before the target operating system is started in the target machine, the BIOS in the target machine may control the starting amount of the CPU in the target machine, and allocate the available area and the reserved area of the physical memory.
It should be noted that, the CPU and the memory resources of the target machine are controllable, and when the target engineering progress starts to run, all the available physical memory resources of the target machine are visible to the target engineering progress, so that the use of the physical resources of the target machine can be further controlled by the target engineering progress.
In an alternative embodiment provided in the present application, as shown in fig. 6, step S23 of starting a target operating system in a target machine, synchronizing information to be synchronized to the target machine includes:
step S231, the memory data forwarded by the target MOC card is written into the memory space of the target machine through the target operating system;
in step S233, the target operating system adjusts the CPU state and the controller state of the target machine to be synchronous with the CPU state and the controller state of the source machine according to the CPU data and the controller data forwarded by the target MOC card.
In the above steps S215 and S217, the target machine may acquire the memory data, the CPU data and the controller data transmitted by the source machine through the MOC card, and write the memory data forwarded by the target MOC card into the memory space of the target machine through the target operating system running on the target machine, control the CPU state of the target machine according to the CPU data forwarded by the target MOC card, control the controller state of the target machine according to the controller data forwarded by the target MOC card, synchronize the memory data of the target machine with the memory data of the source machine, synchronize the CPU state of the target machine with the CPU state of the source machine, synchronize the controller state of the target machine with the controller state of the source machine, thereby implementing synchronization of the target machine with the source machine, and complete thermal migration of the source instance to the target instance running on the target machine.
In the embodiment of the invention, the information to be synchronized of the source machine is transmitted through the target MOC card and the source MOC card, and is forwarded to the target machine, so that the target machine can acquire the information to be synchronized of the source machine, and then the information to be synchronized is synchronized to the target machine through the target operating system on the target machine, thereby achieving the aim of synchronizing the source machine and the target machine, realizing the technical effect of thermally migrating the source instance running on the source machine to the target instance running on the target machine, and further solving the technical problem that the instance cannot be thermally migrated in the scene based on the micro server MOC virtualization technology on the card.
It should be noted that, for simplicity of description, the foregoing method embodiments are all described as a series of acts, but it should be understood by those skilled in the art that the present invention is not limited by the order of acts described, as some steps may be performed in other orders or concurrently in accordance with the present invention. Further, those skilled in the art will also appreciate that the embodiments described in the specification are all preferred embodiments, and that the acts and modules referred to are not necessarily required for the present invention.
From the description of the above embodiments, it will be clear to a person skilled in the art that the method according to the above embodiments may be implemented by means of software plus the necessary general hardware platform, but of course also by means of hardware, but in many cases the former is a preferred embodiment. Based on such understanding, the technical solution of the present invention may be embodied essentially or in a part contributing to the prior art in the form of a software product stored in a storage medium (e.g. ROM/RAM, magnetic disk, optical disk) comprising instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the method according to the embodiments of the present invention.
Example 2
The invention is illustrated by a more detailed embodiment in which an example thermo-migration scheme based on MOC virtualization technology is described in detail below.
FIG. 7 is a schematic diagram of an example hot migration scheme based on an alternative MOC virtualization technology according to an embodiment of the present application, as shown in FIG. 7, instance A is a source instance, and a physical machine (i.e., a source machine) where the source instance is located is machine A (i.e., machine A), where machine A has a specification of 64C 128GB; instance B (i.e., instance B) is a target instance, and the physical machine (i.e., target machine) on which the target instance resides is machine B (i.e., machine B), where machine B has a specification of 128C 256GB. MOC a is the MOC card of instance a (i.e., source MOC card) in which MOC OS a (i.e., source operating system, or operating system a) is running; similarly, MOC B is the MOC card of instance B on the machine (i.e., the target MOC card) within which MOC OS B (i.e., the target operating system, or operating system B) is running.
It should be noted that the specification of example B is larger than that of example a.
When a migration from instance a to instance B needs to be initiated, a worker OS (i.e., the target work process, or work process B) is first started on machine B, and the target work process uses only a small portion of the CPU and a small portion of the memory Mum of machine B.
Subsequently, the worker a in the operating system a (i.e., the source work process, or work process a) communicates with the work process worker B in the operating system B (i.e., the target work process, or work process B), which functions to send the memory data of the instance a to the work process B continuously. At the same time, the work process B communicates with the work process B through the connection bus of the target MOC card and the host, and the memory data received from the work process A is synchronized and written into the memory of the machine B. When the memory data occupying the maximum proportion of the transmission quantity synchronously converges to a certain degree, the working process A and the working process B synchronously acquire the CPU state and data, the states of various controllers and the like.
When the states of the two physical machines (i.e. the machine a and the machine B) are finally consistent, the working process a synchronizes the TDC and the VPORT into the operating system B, so that all states of the machine a and the machine B are consistent, then, the execution of the CPU instruction of the machine a is stopped, the working process B in the machine B is notified to start executing the instruction of the machine a in the memory, and thus, the hot upgrading process of the example is realized.
It should be noted here that TDC and VPORT are a unique concept under ECS MOC architecture, which can be understood as simply a logical implementation of cloud disk and elastic network card in the ECS bottom layer. On a server accessing and using a MOC card, the IO requests (network, disk) of the server are relayed through the MOC, the TDC in the operating system of the MOC card is used to relay disk IO requests, and the VSwitch component is used to relay network requests. Each network card seen by the server corresponds to the VPORT in the VSwitch component one by one. And the IO related components such as TDC, VPORT and the like are synchronized, so that smooth transition of IO requests in the migration process can be ensured.
