Description
Technical Field
The present application relates to the field of virtual machine technologies, and in particular, to a method and an apparatus for creating a virtual machine template and accessing a virtual machine, and a storage medium.
Background
In the internet today, cloud computing is absolutely a popular technology. The things are interconnected, especially. As an underlying application of cloud computing technology, virtualization is one of the most important technologies. Through the virtualization technology, one hardware server or a common PC can be virtualized into a plurality of virtual machines, and the virtual machines can operate independently without any influence. In an enterprise-level virtualization solution, a vSphere virtualization suite introduced by VMware is famous for characteristics of simplicity, easiness in use, stability, reliability and the like, and is deeply favored by various large internet companies.
In the vSphere virtualization suite, the two most important core components are the ESXi server and the virtual center server vcenter server. ESXi acts as a hypervsior (virtual monitor) allowing a running virtual machine and associated virtual machine devices to be created thereon. The vCenterServer is used as management software and is responsible for managing and maintaining a plurality of ESxi hosts and related resources on the ESxi hosts. Based on the two core components, hundreds of virtual machines can be easily created, and the whole life cycle of the virtual machines can be managed.
Currently, in the vSphere virtualization suite, a virtual machine can be created by several methods:
1. creating an empty virtual machine through a newly-built virtual machine function provided by ESxi, and then loading an iso mirror image through starting up to carry out system installation on the empty virtual machine;
2. the creation of the virtual machine is realized by importing the previously exported virtual machine template into the ESxi through an ovf deployment function provided by the ESxi;
3. cloning the existing virtual machine or virtual machine template through vCenter Server management software to realize the creation of the virtual machine;
4. copying and copying the folder of the existing virtual machine through a file copying function provided by DataStore in the ESxi, and then re-registering the copied virtual machine into the ESxi to realize the creation of the virtual machine;
5. based on ssh (secure shell protocol) connection to the ESxi host, the virtual machine is copied to the target ESxi by means of scp remote virtual machine folder copy, and then the virtual machine is registered in the target ESxi to the list to realize the creation of the virtual machine.
In the implementation method, the deployment mode through ovf is fastest under the same virtual machine configuration (generally referred to as disk capacity). For example, the capacity of the virtual machine disk is 40G, and the capacity of the disk after the reduction and the standby is 10G is derived ovf. It takes about several minutes to import it into ESXi by way of ovf deployment. This is only the time of booting, and after booting, the virtual machine needs to be booted, and the whole booting process also needs 1 minute at least.
With the method for creating a virtual machine provided in the existing vSphere virtualization suite, the creation of a second-level virtual machine and the startup of the virtual machine into a system cannot be realized at all. Therefore, how to create the second-level virtual machine and start the system is a technical problem that needs to be solved urgently by those skilled in the art.

Detailed Description
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.
First, before describing the technical solution provided by the present application in detail, the reason for pursuing the creation of a second-class virtual machine or the creation of a virtual machine as fast as possible will be described. For example: if a company develops a product that involves underlying virtualization, such as: the experimental training environment of network training and the scene topology environment of network safety attack and defense training are naturally that the faster the user clicks to enter the experiment, the better the user experience. Therefore, it is necessary to create and enter the second-level virtual machine into the system.
In order to implement second-level virtual machine creation and entry into a system, as shown in fig. 1, an embodiment of the present application provides a virtual machine template creation method, including the following steps:
wherein, the ESxi server is a core component in the vSphere virtualization suite. The created first data storage area is used for storing disk data of the first virtual machine.
In a specific implementation, creating the first data storage area may be implemented by: deploying a Ceph environment and creating a Ceph rbd block in the Ceph environment; accessing a Ceph rbd block to an ESxi server to create a first data storage area in the ESxi server; wherein the storage capacity of the first data storage area is the same as the storage capacity of the Ceph rbd block.
The Ceph is a very popular open source distributed storage system at present, has the advantages of high expansibility, high performance, high reliability and the like, and provides a block storage service (rbd), an object storage service (rgw) and a file system storage service (cephfs), wherein the Ceph fully utilizes the computing power of storage nodes during storage, and obtains the position of each data through computation during storage, so that the distribution is balanced as much as possible. When creating a Ceph rb block in a Ceph environment, at least one Ceph rb block may be created as needed.
specifically, a Windows virtual machine is created by importing or creating a new virtual machine function provided in ESXi, where the disk capacity is 40G, and in addition, during the specific implementation, the storage capacity of the first data storage area created in step 101 may be the same as the disk capacity of the Windows virtual machine, that is, 40G. When creating the first virtual machine selection data storage, the first data storage area created in step 101 needs to be selected as a storage location of the disk data of the first virtual machine.
specifically, after the Windows virtual machine is created, a VMtools enhancement tool is installed, then a boot instruction is obtained, and the Windows system is accessed based on the boot instruction. The VMtools are mainly used for display optimization and adjustment of the virtual host, and in addition, the interaction between the virtual host and the physical machine can be facilitated, for example, a folder can be shared between the physical machine and the virtual machine, even files can be directly dragged and dropped from the physical host to the virtual host, seamless switching of a mouse, adjustment of display resolution and the like, so that the VMtools are very practical.
104, creating a memory snapshot for the first virtual machine system to complete the creation of a virtual machine template; the memory snapshot is used for realizing second-level access to the virtual machine system.
Wherein step 104 is the key to implementing second level entry into the virtual machine system. In specific implementation, virtual machine templates of different systems can be created as required, for example: a virtual machine template of a Windows 7 system, a virtual machine template of a Windows 10 system, etc. Generally, a template is manufactured once for one system version. For example, win7 template, win8 template, win10 template. Later when it is desired to create a win7 virtual machine, it may be created directly through the win7 template.
In the embodiment of the application, after a first virtual machine is created in an ESXi server, the first virtual machine system of the first virtual machine is entered, a memory snapshot is created for the first virtual machine system, and a virtual machine template is obtained, wherein the memory snapshot is used for achieving second-level entry into the virtual machine system, so that the snapshot is restored for a created target virtual machine subsequently, and second-level entry into the target virtual machine system becomes possible.
As shown in fig. 2, an embodiment of the present application provides a virtual machine entry method, which includes the following steps:
in specific implementation, a new Ceph rbd block is created based on a COW (copy-on-write) technology, and the method specifically comprises the following steps: creating a snapshot for the Ceph rbd block to obtain a Ceph rbd block snapshot; performing protection on the Ceph rbd block snapshot; and performing link cloning based on the protected Ceph rbd block snapshot to generate a new Ceph rbd block. The new Ceph rbd block generated by the Link clone is then mapped out by the Ceph iSCSI Target cli command. The purpose of the mapping is to allow the ESxi to interact with the Ceph iSCSI Target through the iSCSI protocol, and further allow the ESxi to access and use a new Ceph rbd block.
and (3) accessing the new Ceph rbd block to an ESxi server through an iSCSI protocol, and after the access is successful, adding a new storage area, namely a second data storage area, in the ESxi again.
and entering a newly added second data storage area, and registering the virtual machine registration file (vmx file of the virtual machine) corresponding to the virtual machine template to the ESxi server, wherein a new virtual machine is successfully created.
and step 206, executing snapshot recovery operation on the target virtual machine, and entering the target virtual machine system.
Because the memory snapshot is created for the virtual machine system when the virtual machine template is created, after the target virtual machine is created by using the virtual machine template, the snapshot operation is executed for the created target virtual machine, and the target virtual machine system can be accessed in a second level.
In the embodiment of the application, a virtual machine template with a memory snapshot created in advance is adopted, the memory snapshot is created in the starting state of the virtual machine, the starting state of the virtual machine template is stored in the memory snapshot, and the snapshot recovery operation is used for recovering the virtual machine to the starting state of the virtual machine stored in the snapshot, so that the second-level virtual machine creation and system entry are realized.
During specific implementation, the second-level vSphere virtual machine creation and system entry functions are finally achieved through combination of multiple technologies such as ESxi, Ceph rbd, Ceph iSCSI, ESxi iSCSI access, virtual machine memory snapshot, Ceph SDK (distributed file system software installation package) and vSphere SDK programming.
In order to further explain the method for creating a virtual machine at the second level and booting the virtual machine to enter the system provided by the embodiment of the present application, the embodiment of the present application is further explained according to the following three parts.
A first part: the early preparation mainly comprises the environment deployment of a Ceph rbd cluster and a Ceph iSCSI service;
a second part: creating a virtual machine template of a second-level access system;
and a third part: the method comprises the steps that a virtual machine is created in a second level mode and enters a system based on a Ceph rbd and a virtual machine template entering the system in the second level mode;
the first two parts only need to be prepared once, and the second part can be directly realized through the third part when a virtual machine needs to be created in a second level and enters the system.
For convenience of understanding, referring to fig. 3, fig. 3 shows an overall flowchart of creating a virtual machine and entering the virtual machine, taking a single ESXi server, 4T capacity data storage as an example, and the specific implementation steps are as follows:

1.1, initializing an ESxi server: and emptying the ESxi server to ensure that the data storage is empty and no other data occupies the space of the data storage.
1.2, in the ESxi server, newly building a second virtual machine: specifically, a virtual machine of Centos7.x is created through the newly-built virtual machine function provided by ESxi, and the disk capacity of the virtual machine is configured to be 4T, so that the disk capacity of the virtual machine occupies the space of the whole data storage (usually only 3.9T).
1.3, installing a second virtual machine system on the second virtual machine: the disk partitions are divided such that the system disk occupies 100G (/ dev/sda1), and the remainder are all divided into a separate partition for the data storage disk of Ceph (/ dev/sda 2).
1.4, configuring a Ceph environment on the second virtual machine system:
1.4.1, deploying a Ceph rbd cluster; wherein deploying the Ceph rbd cluster is used to create at least one Ceph rbd block; specifically, a Ceph-deployment automation deployment tool is used for deploying a Ceph rbd cluster with the number of nodes being 1 mon node, 1 mgr node and 1 osd node, wherein the rbd cluster is used for providing disk storage services for virtual machines created at the next second level.
1.4.1.1 installation of ceph related component packages: the package of components is installed by yum, where yum is a package manager under centos, and the ceph-deployment package of components is installed by yum.
1.4.1.2 deploy mon, mgr and osd nodes.
The mon node is a manager of the cluster state, and maintains the state of the whole cluster. The primary function of the mgr node is to expose some of the indices of the cluster to outside use. osd is an object storage resource in Ceph.
1.4.2, deploying an iSCSI Target service, wherein the iSCSI Target service is used for accessing the Ceph rbd blocks in the Ceph rbd cluster into an ESxi server.
Specifically, the iSCSI Target service is deployed to map the Ceph rbd block out using the standard iSCSI protocol, so that ESXi can access the mapped Ceph rbd block through the iSCSI protocol, and the specific deployment mode is as follows:
1.4.2.1 install tcmu-runner kit;
the tcmu-runner toolkit is used for transferring kernel read-write operations to a user mode layer based on kernel-user mode communication, and the tcmu-runner supports a plurality of plug-ins including ceph rbd.
1.4.2.2 installing a Ceph-iSCSI protocol package;
wherein the Ceph-iSCSI protocol package provides iSCSI protocol.
Also for 1.4.2.1 and 1.4.2.2, yum means.
1.4.2.3 configuring and initiating an iSCSI gateway; the iSCSI gateway is used for enabling a Ceph rbd block to access to an ESxi server based on an iSCSI protocol;
1.4.2.4 configuring iSCSI Target service; the iSCSI Target service is used for providing storage resources, and specifically includes:
creating a first service end;
creating a first client, and setting a user name and a password of the first client for verification during ESxi access; and the user name and the password of the first client are used for configuring the iSCSI storage adapter in the second part.
Thus, the preliminary preparation work is completed.
And a second part, creating a virtual machine template with a second level entering the virtual machine system:
2.1, in a Ceph environment, creating a Ceph rbd block and mapping the block out through a Ceph iSCSI Target service (taking a windows virtual machine template with the disk capacity of 40G as an example).
Specifically, a Ceph rbd block is created through a Ceph iSCSI cli command line, and the created rbd block is mapped out.
2.2, accessing the 40G Ceph rbd block created in the last step in the ESxi through an iSCSI protocol, wherein after the access is successful, the ESxi shows that one more data storage with the capacity of 40G is added in the data storage of the ESxi.
2.2.1 adding iSCSI storage adapter;
2.2.2 configuring an iSCSI storage adapter;
selecting a newly added iSCSI adapter, and then clicking the lower right corner attribute; configuring the name of an iSCSI client in a conventional configuration, and configuring the name of the iSCSI client as the name of a first client in a first part as a second client;
2.2.3 configuring iSCSI Target information;
the iSCSI Target may be understood as a server, a second server is added in the dynamic discovery, and the address information of the second server is configured to be the same as that of the first server, because the address of the server needs to be known when communication is to be achieved;
and clicking the CHAP to configure the identity authentication information, configuring the CHAP authentication information, and using the user and the password set by the first client in the first part.
2.2.4 adding iSCSI data storage (first data storage area);
2.2.4.1 rescanning the storage area entirely to find a mapped Ceph rbd block;

At this time, a first newly added data storage area can be seen in the data storage list of the ESxi, and the first data storage area is used for storing relevant data of the virtual machine template;
2.3 through the function of the newly-built virtual machine provided by the import or ESxi, a Windows virtual machine is created, the disk capacity is 40G, it is noted that when selecting the data storage, the newly-added data storage (the first data storage area) in the previous step needs to be selected, so as to finally realize the storage of the disk data of the virtual machine in the Ceph rbd block.
2.4. After the Windows virtual machine is successfully established, a VMtools enhancing tool is installed, and then the Windows virtual machine is started to enter a Windows system desktop;
2.5. after entering the system, the operation of creating the memory snapshot is executed on the Windows virtual machine system, which is a very critical step for realizing the second-level entry of the system.
And a third part: the method comprises the following steps that a virtual machine is created at a second level and enters a system based on a Ceph rbd block and a virtual machine template of the second-level entry system:
3.1, link cloning is executed on a Ceph rbd block where a second level enters a system virtual machine template through an rbd command, so that the second level creates a new Ceph rbd block based on a COW (copy-on-write) technology, and the method specifically comprises the following steps:
