Embodiment 1
[0027] According to the embodiment of the present application, an embodiment of a method for migrating a virtual machine is also provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.
[0028] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. figure 1 A block diagram of a hardware structure of a computer terminal (or mobile device) for implementing a virtual machine migration method is shown. Such as figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more (shown by 102a, 102b, ..., 102n in the figure) processor 102 (the processo...
Embodiment 2
[0068] Figure 4 is a flow chart of another virtual machine migration method according to an embodiment of the present application, such as Figure 4 As shown, the method includes the following steps:
[0069] Step S402, acquiring an instruction sent by the source device to create a target virtual machine running on the target device.
[0070] Step S404, obtaining the memory management mode of the source device from the above instruction.
[0071] Step S406, creating the target virtual machine according to the memory management mode of the source device.
[0072] Steps S402 to S402 provide another virtual machine migration method, wherein, related content about virtual machine migration can be found in figure 2 Relevant descriptions of the illustrated embodiments will not be repeated here. Here, only the operations performed by the target segment host during the live migration of the virtual machine are described.
[0073] After receiving the instruction to create a virt...
Embodiment 3
[0082] According to an embodiment of the present application, a migration device for implementing the above virtual machine migration method is also provided, Figure 5 is a structural diagram of a virtual machine migration device according to an embodiment of the present application, such as Figure 5 As shown, the device includes:
[0083] An acquisition module 50, configured to acquire the memory management mode of the target device;
[0084] A comparison module 52, configured to compare the memory management method of the target device with the memory management method of the source device;
[0085] A determination module 54, configured to determine the creation method of the target virtual machine running on the target device according to the comparison result;
[0086] The migration module 56 is configured to migrate the memory and device state of the source virtual machine running on the source device to the target virtual machine created in the above creation manner....
