Detailed Description
The core of the application is to provide a high availability method, a system and a related device of a virtual machine
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a high availability method for a virtual machine according to an embodiment of the present disclosure, where the method includes:
s101: receiving a network card application request sent by a virtual machine;
s102: judging whether the network card application request contains a fault code or not; if yes, entering S103;
s103: marking the physical network card state of the virtual machine as unavailable in a resource pool, selecting a target network card from the resource pool as a direct connection network card of the virtual machine, and configuring a unique MAC address for the virtual machine; and the unique MAC address is used for covering the MAC address of the target network card before the virtual machine establishes network connection.
The physical network card of each host is provided for the virtual machine in a form of a resource pool of the direct connection network card, and the attribute of the physical network card in the resource pool comprises the following steps: host, physical network card name, specification, PIC address, status, etc.
If the virtual machine needs to use the direct-connection network card, the virtual machine needs to apply from the direct-connection network card resource pool, and after the application is successful, the virtual machine runs on the host where the direct-connection network card is located.
If the host where the virtual machine is located is crashed and has a fault, the cloud management platform marks the physical network card state of the faulted host as unavailable in the direct connection network card resource pool, selects a proper target host and a proper physical network card for the virtual machine, the target host must have the physical network card with the same specification as the original host in the direct connection network card resource pool, marks the physical network card state of the target host as used by the cloud management platform, and starts the virtual machine at the target host.
The cloud management platform assigns a unique MAC address for the virtual machine when the virtual machine is created, the unique MAC address is not changed due to the change of the direct network card, and the virtual machine does not need to make any network adjustment after the new host is successfully available. Particularly, the MAC address of the direct connection network card of the virtual machine is planned uniformly by the cloud management platform, and is responsible for specific execution and maintenance by vmtools in the virtual machine, each time the host position of the virtual machine changes, the cloud platform can transmit the planned MAC information to the vmtools in the virtual machine, and the MAC address of the direct connection physical network card is covered by the vmtools before the network service in the virtual machine is pulled up.
It should be noted that, instead of configuring the unique MAC address after each failure of the virtual machine, if the unique MAC address has been configured for the virtual machine before, the configuration may not be performed after that, but at least a determination process of whether the unique MAC address is configured should be performed.
Preferably, after the unique MAC address is configured for the virtual machine, the mapping relationship between the virtual machine and the unique MAC address may be saved. The saving is mainly saved in the cloud management platform, and the specific storage address is not specifically limited herein.
Preferably, a resource pool may be created first, where the resource pool is used to provide a direct network card to the virtual machine; the attribute of the network card in the resource pool comprises at least one of a network card specification, a PIC address and a network card state.
In addition, if the network card application does not contain the fault code, the corresponding pass-through network card can be determined according to the configuration information of the virtual machine in the network card application request, so that the virtual machine can apply the pass-through network card and start. When the network card application does not contain the fault code, which indicates that the virtual machine may apply for the network card for the first time, the target network card can be selected from the resource pool as the straight-through network card of the virtual machine according to the network card specification in the network card application request, wherein the network card specification is the physical network card specification before the virtual machine fails.
For example, when the virtual machine VM1 runs on the host1, the physical network card of the host1 is used as a pass-through network card, the mac address of the virtual machine VM1 configured by the cloud management platform is macX, and when the virtual machine runs for the first time and the host position changes, the virtual machine VM is modified from vmtools to macX.
When host1 goes down, virtual machine VM1 starts up on host2, that is, when the host location of the virtual machine changes, virtual machine VM1 uses the physical network card of host2 as a pass-through network card, but the mac address is still macX and does not change. It is also possible to change the unique MAC address from macX to a second MAC address and modify the mapping, but usually without change.
The following describes a high availability system of a virtual machine provided by an embodiment of the present application, and the high availability system of a virtual machine described below and the high availability method of a virtual machine described above may be referred to correspondingly.
