[0050] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0051] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.
[0052] Figure 1 This is a flowchart illustrating a virtual machine migration method provided in an embodiment of this disclosure. This method can be executed by an electronic device. The electronic device can be exemplarily understood as a device such as a mobile phone, tablet computer, laptop computer, desktop computer, or smart TV. Figure 1 As shown, the method provided in this embodiment includes the following steps:
[0053] S101. If a migration operation of a virtual machine on the current host is detected, the current migration mode is determined; wherein the current migration mode is either cold migration mode or hot migration mode.
[0054] In one example, the current host is the physical host to be migrated. The virtual machine migration operation moves the virtual machine from the current host to the target host. The target host is the physical host after the migration.
[0055] In one example, cold migration mode involves migrating the virtual machine while it is powered off. Hot migration mode involves migrating the virtual machine while it is powered on.
[0056] S102. Based on the current migration mode, process the first virtual machine network interface to obtain the second virtual machine network interface; wherein, the first virtual machine network interface is used to represent the network interface created on the current host.
[0057] In one example, the first virtual machine network interface represents the network interface created on the current host. This first virtual machine network interface is the virtual interface used by the virtual machine to communicate with the external network before migration. The second virtual machine network interface is the virtual interface used by the migrated virtual machine to communicate with the external network. Specifically, the way the first virtual machine network interface is handled differs depending on the current migration mode.
[0058] S103. According to the current migration mode, the first virtual IP address is processed to obtain the second virtual IP address; wherein, the first virtual IP address is used to represent the address of the virtual machine service; the first virtual IP address and the first virtual machine network interface have a first association relationship.
[0059] In one example, the first virtual IP address is used to represent the address of the virtual machine service. The first virtual IP address and the first virtual machine network interface have a first association relationship. Further, for example, if the first virtual machine network interface is VI F1 and the first virtual IP address is VIP1, then VI F1 and VIP1 have a first association relationship.
[0060] In one example, the way the first virtual IP address is handled differs depending on the current migration mode.
[0061] S104. Obtain configuration information from the preset database, and based on the configuration information, create a second virtual machine network interface and a second virtual IP address on the target host to complete the migration of the virtual machine from the current host to the target host.
[0062] In one example, the configuration information indicates how to create a second virtual machine network interface and a second virtual IP address on the target host. In this embodiment, the configuration information in the preset database can be pre-set or generated in real time.
[0063] This disclosure provides a virtual machine migration method, which includes: if a migration operation of a virtual machine on the current host is detected, determining the current migration mode; wherein the current migration mode is a cold migration mode or a hot migration mode; processing a first virtual machine network interface according to the current migration mode to obtain a second virtual machine network interface; wherein the first virtual machine network interface is used to represent a network interface created on the current host; processing a first virtual IP address according to the current migration mode to obtain a second virtual IP address; wherein the first virtual IP address is used to represent the address of a virtual machine service; the first virtual IP address and the first virtual machine network interface have a first association relationship; obtaining configuration information from a preset database, and creating a second virtual machine network interface and a second virtual IP address on the target host according to the configuration information, so as to complete the migration of the virtual machine from the current host to the target host. Using this technical solution can improve the completeness and accuracy of the migration of the virtual machine's network interface and its bound virtual IP address.
[0064] Figure 2a This illustration shows a flowchart of a virtual machine migration method provided by an embodiment of the present disclosure. The embodiments of the present disclosure are optimized based on the above embodiments, and can be combined with various optional solutions from one or more of the above embodiments.
[0065] like Figure 2a As shown, the virtual machine migration method may include the following steps:
[0066] S201. If a migration operation of a virtual machine on the current host is detected, the current migration mode is determined; wherein the current migration mode is either cold migration mode or hot migration mode.
[0067] In one example, this step can be found in step S101.
[0068] S202. If the current migration mode is cold migration mode, then according to the current migration mode, the first virtual machine network interface is processed to obtain the second virtual machine network interface, including: deleting the second association relationship between the first virtual machine network interface and the current host in the preset database, and generating the second virtual machine network interface in the preset database.
[0069] In one example, the first virtual machine network interface is used to represent the network interface created on the current host. In this embodiment, since the first virtual machine network interface is used to represent the network interface created on the current host, there is a second association between the first virtual machine network interface and the current host. In cold migration mode, the second association between the first virtual machine network interface and the current host needs to be deleted from the preset database. The advantage of this setting is that it can prepare for virtual machine migration. Further, a second virtual machine network interface is generated in the preset database. The advantage of this setting is that the migrated virtual machine can be connected to the external network through the second virtual machine network interface.
[0070] S203. If the current migration mode is cold migration mode, then according to the current migration mode, the first virtual IP address is processed to obtain the second virtual IP address, including: removing the first association between the first virtual IP address and the first virtual machine network interface, and determining the first virtual IP address as the second virtual IP address.
[0071] In one example, the first virtual IP address is used to represent the address of the virtual machine service; the first virtual IP address has a first association relationship with the first virtual machine network interface.
[0072] In one example, since there is a first association between the first virtual IP address and the first virtual machine network interface before the virtual machine migration, and the first virtual IP address will not change in cold migration mode, it is necessary to first remove the first association between the first virtual IP address and the first virtual machine network interface, and then determine the first virtual IP address as the second virtual IP address.
[0073] S204. Establish a third association between the second virtual machine network interface and the target host.
[0074] In this embodiment, after determining the second virtual machine network interface, the second virtual machine network interface is associated with the target host, and then a third association relationship between the second virtual machine network interface and the target host is obtained.
[0075] S205. Establish a fourth association between the second virtual IP address and the second virtual machine network interface.
[0076] In one example, the second virtual IP address is associated with the second virtual machine network interface, resulting in a fourth association. The advantage of this setup is that by establishing this association, the virtual IP address can be prevented from being lost during virtual machine migration.
[0077] S206. Based on the third and fourth association relationships, generate configuration information in the preset database.
[0078] In one example, the third and fourth associations are used to generate configuration information that indicates how to create a second virtual machine network interface and a second virtual IP address on the target host.
[0079] S207. Obtain configuration information from the preset database, and based on the configuration information, create a second virtual machine network interface and a second virtual IP address on the target host to complete the migration of the virtual machine from the current host to the target host.
[0080] In one example, this step can be found in step S104.
[0081] For a clearer explanation, please refer to [link to relevant documentation]. Figure 2b The diagram shows an architecture diagram under a cold migration mode.
[0082] This disclosure provides a virtual machine migration method, which includes: if the current migration mode is a cold migration mode, processing a first virtual machine network interface to obtain a second virtual machine network interface according to the current migration mode, including: deleting a second association between the first virtual machine network interface and the current host in a preset database, and generating a second virtual machine network interface in the preset database; if the current migration mode is a cold migration mode, processing a first virtual IP address to obtain a second virtual IP address according to the current migration mode, including: removing a first association between the first virtual IP address and the first virtual machine network interface, and determining the first virtual IP address as the second virtual IP address; establishing a third association between the second virtual machine network interface and the target host; establishing a fourth association between the second virtual IP address and the second virtual machine network interface; generating configuration information in the preset database according to the third and fourth associations; obtaining the configuration information from the preset database, and creating a second virtual machine network interface and a second virtual IP address on the target host according to the configuration information, to complete the migration of the virtual machine from the current host to the target host. This technical solution can improve the efficiency and stability of virtual machine migration.
[0083] Figure 3a This illustration shows a flowchart of a virtual machine migration method provided by an embodiment of the present disclosure. The embodiments of the present disclosure are optimized based on the above embodiments, and can be combined with various optional solutions from one or more of the above embodiments.
[0084] like Figure 3a As shown, the virtual machine migration method may include the following steps:
[0085] S301. If a migration operation of a virtual machine on the current host is detected, the current migration mode is determined; wherein the current migration mode is either cold migration mode or hot migration mode.
[0086] In one example, this step can be found in step S101.
[0087] S302. If the current migration mode is hot migration mode, then the first virtual machine network interface is processed according to the current migration mode to obtain the second virtual machine network interface, including: adding the migration status of the virtual machine to the preset database, and establishing the second virtual machine network interface in the preset database according to the first virtual machine network interface.
[0088] The first virtual machine network interface is used to characterize the network interface created on the current host.
[0089] In one example, the migration status of a virtual machine is used to indicate that the virtual machine is in the process of migration. For example, the first virtual machine network interface is VI F1, and the second virtual machine network interface is VI F2. In this embodiment, VI F1 and VI F2 exist simultaneously in the preset database at this time.
[0090] S303. If the current migration mode is hot migration mode, then according to the current migration mode, the first virtual IP address is processed to obtain the second virtual IP address, including: determining the first virtual IP address as the second virtual IP address.
[0091] In one example, the first virtual IP address is used to represent the address of the virtual machine service. The virtual IP address does not change in hot migration mode; therefore, the first virtual IP address is designated as the second virtual IP address.
[0092] S304. Establish the fifth association between the second virtual IP address and the second virtual machine network interface.
[0093] In one example, the second virtual IP address is associated with the second virtual machine network interface to obtain the fifth association.
[0094] S305. Based on the fifth association relationship, generate configuration information in the preset database.
[0095] In one example, the configuration information includes a fifth association, and this configuration information is used to indicate how to create a second virtual machine network interface and a second virtual IP address on the target host.
[0096] S306. Obtain configuration information from the preset database, and based on the configuration information, create a second virtual machine network interface and a second virtual IP address on the target host to complete the migration of the virtual machine from the current host to the target host.
[0097] In one example, this step can be found in step S104.
[0098] S307. Delete the second association between the first virtual machine network interface and the current host in the preset database.
[0099] In one example, in hot migration mode, after the virtual machine migration is completed, the second association between the first virtual machine network interface and the current host can be disconnected and deleted from the preset database.
[0100] S308. Remove the first association between the first virtual IP address and the first virtual machine network interface.
[0101] In one example, the second virtual IP address, which is the first virtual IP address, has already been associated with the second virtual machine network interface. At this time, after the virtual machine is migrated, the first association between the first virtual IP address and the first virtual machine network interface can be broken.
[0102] S309. Retrieve the current configuration information of the virtual machine in the target host, compare the current configuration information of the virtual machine with the configuration information in the preset database, and if they are inconsistent, send an error message.
[0103] In one example, to ensure the correctness of the migration process, the current configuration information of the virtual machine can be compared with the configuration information in the preset database. If they are inconsistent, an error message can be sent in time for timely correction.
[0104] For a clearer explanation, please refer to [link to relevant documentation]. Figure 3b The diagram shows an architecture under a hot migration mode.
[0105] This disclosure provides a virtual machine migration method, which includes: if the current migration mode is a hot migration mode, processing a first virtual machine network interface according to the current migration mode to obtain a second virtual machine network interface, including: adding the migration status of the virtual machine to a preset database, and establishing the second virtual machine network interface in the preset database according to the first virtual machine network interface. If the current migration mode is a hot migration mode, processing a first virtual IP address according to the current migration mode to obtain a second virtual IP address, including: determining the first virtual IP address as the second virtual IP address. Establishing a fifth association relationship between the second virtual IP address and the second virtual machine network interface.

Deleting a second association relationship between the first virtual machine network interface and the current host in the preset database. Deactivating a first association relationship between the first virtual IP address and the first virtual machine network interface. The system retrieves the current configuration information of the virtual machine on the target host and compares it with the configuration information in a pre-set database. If they do not match, an error message is sent. This technical solution ensures service continuity during virtual machine migration.
