Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings. The specific method of operation in the method embodiment may also be applied to the device embodiment or the system embodiment. In the description of the present application, "a plurality of" means "at least two". "and/or" describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate that there are three cases of a alone, a and B together, and B alone. A and B are connected, and it can be represented that A and B are directly connected and A and B are connected through C. In addition, in the description of the present application, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not be construed as indicating or implying a relative importance or order.
Currently, in order to realize the dynamic migration of the virtual machine, a mode is adopted that the dynamic migration is realized based on software and apic simulation, on a 'lapic' transparent high-performance virtual machine, the virtual machine directly uses the physical lapic, and the state of the physical lapic is in a physical register, and the dynamic migration method of the hardware transparent virtual machine is lacking because the dynamic migration is realized based on software and lapic simulation.
In order to solve the above-described problems, an embodiment of the present application provides a method for dynamically migrating a virtual machine, which is used for dynamically migrating the virtual machine based on hardware transparent transmission. The method and the device according to the embodiments of the present application are based on the same technical concept, and because the principles of the problems solved by the method and the device are similar, the embodiments of the device and the method can be referred to each other, and the repetition is not repeated.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the application provides a method for dynamically migrating a virtual machine, which can realize dynamic migration based on hardware transparent virtual machines, and the implementation flow of the method is as follows:
And S1, determining the type of the virtual machine to be migrated on the source host.
In order to realize the dynamic migration of the virtual machine based on hardware transparent transmission, the embodiment of the application firstly needs to determine the type of the source host of the virtual machine to be migrated on the source host, the type of the host to be migrated can be a virtual machine capable of being added with 'lapic' transparent transmission, and in the embodiment of the application, the virtual machine to be migrated is a virtual machine capable of being transparent transmission, and the application needs to supplement that lapic in the file is an interrupt controller.
And step S2, storing a data structure corresponding to the interrupt controller which accords with the condition in response to the type being consistent with the preset type.
The type of the virtual machine to be migrated is determined, in order to ensure that the virtual machine to be migrated is a virtual machine of a specified type, the type of the virtual machine to be migrated needs to be matched with each preset type in a preset type set, if the type is matched with a consistent preset type, the type is represented as being in the preset type, and if the type is not matched with the consistent preset type, the type is represented as not being in the preset type.
When the type is consistent with the preset type, determining that each interrupt controller is corresponding to the type, wherein each interrupt controller is provided with a register, the register is used for reading and/or writing, the register type of the register and the data corresponding to the register are extracted from the interrupt controller, the register type can be TPR, APR, PPR, RRD, LDR, DFR, ICR, IRR, ISR, TMR, LVTT, and the like, and the register type can also be other types, and the description is omitted herein.
After the type of the register and the data corresponding to the register are obtained, the type and the data are associated to generate a data structure, and the data structure is stored, which should be noted that, when kvm_ vcpu _ioctl and kvm_get_lapic are called, the data structure may be added to the calling program, and the implementation of saving the physical LAPIC data structure is added to the kvm_ apic _get_state function, which is mainly implemented to save all readable physical LAPIC registers.
Step S3, adding the data structure to migration transmission data of the virtual machine to be migrated;
In the above description, during the migration process of the virtual machine, the KVM is combined with the QEMU to implement the migration of the virtual machine, the QEMU is a model of an open source simulator and a virtual machine supervisor, the QEMU can be used as a user mode simulator to execute codes different from the host architecture by using a dynamic code translation mechanism, the QEMU can also be used as a virtual machine supervisor to simulate a whole system, and other VMM (Xen, KVM, etc) is used to use virtualization support provided by hardware to create virtual machines close to the host performance, each virtual machine corresponds to one QEMU process in the host (host), and vcpu of the virtual machine corresponds to one thread of the QEMU process, and the vcpu is cpu of the virtual machine.
After the data structure is stored, the data structure is added to the migration transmission data of the virtual machine to be migrated, and the data structure of the stored physical LAPIC is added when the destination calls kvm_ vcpu _ioctl or kvm_set_lapic.
Based on the above description, the data structure is stored in the migration transmission data, and since the migration transmission data is stored in the KVM, the storage and recovery of the physical lapic state can be realized.
And step S4, migrating the virtual machine to be migrated from the source host to the target host based on the migration transmission data.
The above description describes that the data structure is added to migration transmission data of the virtual machine to be migrated, and when the source host performs dynamic migration of the virtual machine to the target host, the server controls the source host to migrate the migration transmission data to the target host, thereby implementing dynamic migration based on the hardware transparent virtual machine.
After the target host receives the migration transmission data, the target host starts and resumes the virtual machine corresponding to the interrupt controller of the type described above, or starts a new virtual machine of transparent lapic according to qemu xml configuration, and resumes the physical lapic.
In order to realize the injection of register data in the register, the target host shuts down the corresponding cpu interrupt under host, restores the physical lapic normal register, reads the ir/isr register, re-injects the corresponding interrupt into the register according to the interrupt number, and finally, the server controls the target host to restore virtual machine operation.
Specifically, as shown in fig. 2, in the flow chart of the physical LAPIC dynamic migration source host, in fig. 2, there are QEMU and KVM in the source host, QEMU is a hardware virtualization program, a calling function kvm_get_ apic calls kvm_ vcpu _ioctl or kvm_get_lapic, because the source host exists on the virtual machine when migrating the dynamic virtual machine, host exists on the host, in the process of implementing migration of the virtual machine, it is required to ensure that host interrupt is closed, the cpu is designated to exit to host, all readable registers including physical LAPIC are acquired through a program kvm_ vcpu _ioctl_get_ LAPIC, only the non-Reserved registers are saved, the saved LAPIC states including the physical LAPIC states are saved through a program kvm_ apic _get_get_teand then the saved LAPIC states are migrated to the target host, thereby implementing migration from the source host to the virtual machine.
After the source host sends the virtual machine to the target host, the physical LAPIC dynamic migration target host flowchart is shown in fig. 3, after the QEMU of the target host receives LAPIC status data sent by the source host, the program kvm_put_ apic _state will read the saved LAPIC status information, including the physical LAPIC, and then based on the program kvm_ apic _put and the program kvm_ vcpu _ioctl or the kvm_set_lapic under the condition of closing the host interrupt, the state of LAPIC is read, including the physical LAPIC register into the KVM, the physical LAPIC status is SET by the program bm_ apic _set_state, and part of the readable and writable registers are directly written into the KVM, and because the interrupt request register and the interrupt processing register are read-only registers, the corresponding interrupt is required to be re-injected in the interrupt request register, and the interrupt is described above, when the program is injected in the registers, the program is reset, the qu is reset after the program injection in the registers, the program is reset, the purpose is restored from the virtual host is restored to the virtual machine is achieved, and finally the virtual machine is restored to the target host, and the virtual machine is migrated from the host.
Based on the method, the data structure is stored based on the type of the virtual machine to be migrated, the data structure is added into migration transmission data, and dynamic migration based on the hardware transparent virtual machine is realized in a mode that the migration transmission data is sent from a source host to a target host.
