Embodiment 1

[0051] figure 1 is a flow chart of the virtual machine migration method provided in this embodiment, such as figure 1 As shown, the virtual machine migration method of the present invention includes:

[0052] S101. The DRS defines hosts whose host information meets the same selection criteria as the same host set to form a host set pool.

[0053] The host set pool includes at least one host set. Different host sets are defined by different selection criteria. Each selection criterion defines a set of hosts along a dimension.

[0054] Specifically, one or any combination of the following may be included:

[0055] (a) Define shared storage hosts as shared storage host collections, and there can be multiple shared storage host collections.

[0056] (b) Define hosts supporting Trusted Platform Module (TPM) as a set of trusted hosts.

[0057] (c) According to legal provisions, define hosts satisfying a certain legal requirement as legally restricted host sets, and multiple lega...

[0079] image 3 is a schematic diagram of the virtual machine migration device provided in this embodiment, such as image 3 As shown, the virtual machine migration device of the present invention includes: a host management module 301 , a range determination module 302 and a host determination module 303 .

[0080] The host management module 301 is used to define hosts whose host information meets the same selection criteria as the same host set to form a host set pool.

[0081] The host set pool includes at least one host set. Different host sets are defined by different selection criteria. Each selection criterion defines a set of hosts along a dimension.

[0082] Specifically, the host management module 301 is specifically used for one or any combination of the following:

[0083] The host management module 301 is used to define shared storage hosts as shared storage host sets, and there may be multiple shared storage host sets.

[0084] The host management module 301...

Embodiment 3

[0104] Figure 4 is a schematic diagram of the composition and structure of the virtual machine migration device provided in this embodiment, as shown in Figure 4 As shown, the virtual machine migration apparatus 400 includes: a processor 401 , a communication interface 402 and a memory 403 .

[0105] The communication interface 402 is used to interact with other devices.

[0106] The memory 403 can be a permanent memory, such as a hard disk drive and a flash memory, and has software modules and device drivers in the memory 403 . The software modules can execute various functional modules of the above methods in the embodiments of the present invention; the device driver can be a network and interface driver.

[0107] At startup, these software components are loaded into memory 403, then accessed by processor 401 and execute the following instructions:

[0108] Defining hosts whose host information meets the same selection criteria as the same host set to form a host set p...

Abstract

The invention relates to a virtual machine migration method and device. The method includes the steps that mainframes with mainframe information conforming to the same selection standard are defined as the same mainframe set so as to form a mainframe set pool, wherein the mainframe set pool comprises at least one mainframe set; the migration range of a virtual machine is determined from the mainframe set pool according to configuration items of the virtual machine or the virtual machine migration range property in properties, wherein the virtual machine migration range property is used for determining the migration range of the virtual machine; the target mainframe of the virtual machine is determined in the migration range of the virtual machine. According to the virtual machine migration method and device, a unified model for the migration range of the virtual machine is provided, different migration ranges can be flexibly set for different virtual machines, and management and control over the virtual machines are simplified and unified.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a virtual machine migration method and device. Background technique [0002] Virtual machine live migration (Live Migration) is one of the key features brought about by the decoupling of server software and hardware. Based on this feature, Distributed Resources Scheduler (DRS) implements load balancing, hardware maintenance, energy-saving Ultimate (Killer-level) capabilities such as power management (Distributed Power Management, DPM) and high availability (High Availability, HA). However, there has not been a clear definition of the scope of virtual machine migration. There is no unified model for virtual machine host binding, virtual machine trusted migration, etc., but they are realized through their own technical means, which is not conducive to The management and control of virtual machine migration may bring various security risks and legal risks. [0003] When ...
