the ELF service provides functions related to virtual machine operations, such as creating, deleting, creating snapshots, rolling back, associating vnic, and the like. The VPC service provides VPC network related functions such as vnic creation, deletion, association vnic to VPC-net, etc. vnic contains two pieces of information: VPC related information, such as VPC-net, ip addresses, etc., is stored in the VPC service. mac address, mode, etc. is stored in the ELF service.
When a user needs to create a snapshot for a virtual machine, the user requests an ELF service to create the snapshot for the virtual machine, and the ELF service stores the current information of the virtual machine, wherein the method comprises the following steps: metadata configured by the virtual machine, cpu, memory, storage and the like; vnic, the number of network cards, the mac address of each network card, the network card mode and the like;
When the user desires to roll back the virtual machine to a certain snapshot, the user requests the ELF service to roll back the virtual machine to the designated snapshot, and the ELF service rolls back the virtual machine to the configuration in the snapshot according to the virtual machine information stored in the previous snapshot.

For a virtual machine supporting a vpc network, when the virtual machine rolls back, the information of vnic can only recover the information stored in the ELF, such as mac address, network card mode and the like; for information stored in the VPC, information such as VPC-net, ip address, etc. is lost.
And after the virtual machine creates the snapshot, the network card is deleted, so that the vpc service releases the ip address occupied by the deleted network card at the moment, and even the vpc-net is possibly deleted. When the virtual machine needs to roll back to the configuration in the snapshot, even though the network card information before the virtual machine is reconfigured by means of manual configuration, the situation that the vpc-net is deleted or the ip address is occupied may be found, so that snapshot roll-back failure is caused.

Referring to fig. 2, fig. 2 is a flowchart of a first method for processing a snapshot of a virtual machine VPC network configuration according to an embodiment of the application.
As shown in fig. 2, the present invention provides a method for processing a virtual machine VPC network configuration snapshot, which includes the following operation steps:

S500, finally, virtual machine rollback is realized on the appointed snapshot for the current virtual machine according to the configuration information of the corresponding network card snapshot of the appointed snapshot.
A virtual machine snapshot is a mirror image of a particular file system that has read-only properties for a particular time.
The virtual machine snapshot creation flow is as shown in fig. 3:
the method for responding to the user request to realize the creation processing of the virtual machine snapshot specifically comprises the following steps:
s101, a user still requests ELF service to create a snapshot for a virtual machine, and the snapshot of the virtual machine is obtained;
s102, an ELF service acquires a network card of a VPC network in a virtual machine, and requests a VPC service to create a snapshot for the network card so as to obtain a network card snapshot;

And S104, the ELF service stores virtual machine attribute information, wherein the virtual machine attribute information comprises a network card mac address, a network card mode and a network card snapshot ID returned by the VPC service.
Preferably, as an embodiment; the configuration information of the network card snapshot comprises a vpc network and ip information. Therefore, when the virtual machine is executed to create the snapshot, the configuration information of the network card snapshot needs to be saved, the mapping relation between the network card snapshot ID and the virtual machine attribute information (virtual machine snapshot) can be constructed at the same time, and the virtual machine configuration file corresponding to the configuration information of the network card snapshot is stored at the same time so as to be called when the virtual machine is rolled back.

S304, the VPC service deletes the network card snapshot.
The virtual machine snapshot rollback flow is as follows, as shown in fig. 5:
When detecting that the current user needs to roll back the current virtual machine to the appointed snapshot, obtaining the configuration information of the network card snapshot of the appointed snapshot by obtaining the network card snapshot ID of the appointed snapshot and obtaining the configuration information of the network card snapshot of the appointed snapshot according to the network card snapshot ID of the appointed snapshot and the mapping relation, and specifically comprising the following operation steps:
S401, a user requests ELF service, and virtual machines are rolled back to a specified snapshot;
s402, the ELF service reads the network card snapshot ID of the appointed snapshot;
S403, the ELF service requests the VPC service to acquire configuration information of the network card snapshot corresponding to the specified network card snapshot according to the network card snapshot ID of the specified snapshot; and the VPC service obtains configuration information of the network card snapshot of the specified snapshot according to the network card snapshot ID of the specified snapshot and the mapping relation.
Preferably, as an embodiment; and finally, virtual machine rollback of the current virtual machine on the appointed snapshot is realized according to the configuration information of the corresponding network card snapshot of the appointed snapshot, and the method specifically comprises the following operation steps:
and S404, the ELF service retrieves the virtual machine configuration file from the storage module according to the configuration information of the network card snapshot corresponding to the appointed network card snapshot, updates the virtual machine configuration file to the virtual machine configuration file configured when the appointed snapshot, and realizes virtual machine rollback on the appointed snapshot for the current virtual machine.
In summary, the invention provides a processing method for supporting virtual machine VPC network configuration snapshot, which realizes the function of network card snapshot through VPC, thereby ensuring the accuracy of virtual machine snapshot creation and rollback: the capability of providing the network card snapshot through the VPC service ensures the integrity of the network card information in the virtual machine snapshot, and saves the network card information (namely the configuration information of the network card snapshot) related to the VPC service in the network card snapshot, such as the information of the VPC network, the ip address and the like of the network card. The configuration information of the network card snapshot comprises information such as a vpc network, an ip address and the like of the network card.
Meanwhile, the VPC service can perceive that the VPC network in the snapshot is still used by the virtual machine through the network card snapshot, so that the VPC network is not deleted, the ip address is not occupied by other equipment, and further, even if the virtual machine performs the deletion operation of the VPC network card after the snapshot, the VPC network and the ip address are still available when the snapshot is rolled back, and the snapshot is ensured to be rolled back successfully.
In addition, based on the same concept of the above method embodiment, the embodiment of the present application further provides a snapshot processing system supporting virtual machine VPC network configuration, so as to implement the above method of the present application, and since the principle of solving the problem in the method embodiment is similar to that of the system, the method at least has all the beneficial effects brought by the technical solution of the above embodiment, which is not described in detail herein.
