1. For a compute virtualization module:
computational virtualization is a type of virtualization of a computer or operating system. Virtualization hides the real computer hardware from the user and represents another, abstract, computing platform. The premise of computational virtualization is that all virtual machines share a pool of physical hardware resources.
The pooling of the computing resources is mainly realized by pooling the hardware resources of the server and then distributing the hardware resources to a plurality of virtual machines through a virtualization technology, so that the use efficiency of the physical hardware resources is improved. After the resource pooling management, the calculation, the storage and the network lamp resources can be flexibly distributed according to the requirements of the service system; moreover, hardware equipment can be expanded at will, the capacity of the resource pool is improved, and the requirement of service increase is met.
The solution we provide defaults to using the most secure and high performance KVM hypervisor as the virtualization platform. The KVM is a trusted virtualization environment, and is particularly advantageous for implementation of a multi-tenant environment such as a cloud computing platform.
A physical computer is virtualized into a plurality of logical computers through a virtualization technology, the logical computers are simultaneously operated on the physical computer, each logical computer can operate different operating systems, application programs operate in respective operating systems, the operating systems are independent from each other and do not influence each other, isolation and decoupling of the application programs and hardware resources are achieved, and working efficiency of the computers is remarkably improved. The method for using the software in a virtualization mode redefines and divides the computing resources, can achieve dynamic allocation, flexible scheduling, cross-domain sharing and automatic batch deployment of the computing resources, improves the utilization rate of the computing resources, and meets flexible and variable application requirements.
2. For the network virtualization module:
the network architecture of the virtual desktop platform provided by the embodiment of the invention divides the flow into a management network, an external network, a storage network and a tenant network.
The management network (API network) of the virtual desktop platform provided by the embodiment of the invention is designed as follows:
the management network needs to be connected with each node in the cloud environment, the data transmitted by the management network comprises management flow of a virtualization center to host, HA heartbeat, an SDN controller, a cloud management platform API, a cloud monitoring operation platform and other management flow of management operation components of the cloud computing data center, and the management flow belongs to a neural network of the data center.
The management network is connected with all nodes of the data center, is mainly used for controlling bottom layer resources and calling API, and has low requirement on the network. Typically interconnected through a 1x 1GbE or 1x 10GbE switch network of a server's management network card, typically using a separate access switch.
The tenant network corresponds to a network used by virtual machines between tenants of the cloud data center to communicate. All computing nodes that provide computing services are typically connected. Data of the tenant network is encapsulated into a designated VLAN, the external view is communication between hosts in the VLAN, and internal traffic is invisible.
The tenant network is connected with the computing nodes and the exit area of the cloud data center, and data between virtual machines of the tenants marked through overlay technology are arranged on the tenant network. Tenant networks typically plan multiple vlans to mitigate the effects of broadcast traffic. The number of virtual machines on a physical host is large, and in order to ensure good network quality, the tenant network cards of the server are interconnected through a 1x 10GbE or 1x40GbE switch network.
The external network design of the virtual desktop platform provided by the embodiment of the invention is as follows:
for the external network, as compared with the user, the traffic between the user virtual machines can be completely transmitted through the user network, but when the external network communicates with the outside (usually, the internet, including the data center internal network), the original overlay encapsulation needs to be removed, and the public network IP is mapped. Other network services are included in addition to this, such as: NAT, VPN, firewall, LB, etc.
The software router is designed and realized to connect the tenant network and the external network. Each tenant can create a software router which is exclusive to the tenant, and defines the export strategy by self. External networks are typically interconnected by a 1x 10GbE or 1x40GbE switch network. The external network is typically northbound to conventional switches and routers of the data center.
The storage network design of the virtual desktop platform provided by the embodiment of the invention is as follows:
the storage network is mainly used for connecting the storage nodes and the computing nodes. In a cloud computing data center, storage includes distributed storage and centralized storage. The storage network at least uses a ten-million switch, and the servers are interconnected through a single ten-million network card to form an internal network. Meanwhile, the cluster change information needs to be acquired through multicast, so that the multicast must be supported.
The virtual router of the virtual desktop platform provided by the embodiment of the invention is designed as follows:
the software router is designed and realized to connect the tenant network and the external network. gateway is external gateway, interfaces is internal interface, and the internal interface can be a plurality of, and external gateway only has one, and external gateway and internal interface pass through the router and connect.
3. For the storage virtualization module:
storage virtualization refers to separating a specific storage device or a storage system from a server operating system, and providing a uniform virtual storage pool for storage users. It is an abstraction of a concrete storage device or storage system, presenting a logical view to a user, while separating the application program from the data storage operations and concrete storage controls required by the user. The task of storage virtualization is first to create an abstraction layer over multiple physical storage devices or storage systems, mask complexity, simplify management, and optimize storage resources.
The idea of storage virtualization is to separate the logical image of resources from the physical storage, thereby providing a simplified, seamless virtual view of resources for the system and administrators. The virtualized storage resource appears to the user as a large "storage pool," and the user does not have to be concerned about which path the user's data travels to which particular storage device.
4. For the GPU virtualization module:
the GPU virtualization implementation mode is as follows: the method comprises the steps of virtualizing a physical GPU into a plurality of virtual GPUs, directly allocating each virtual GPU to a virtual machine for use, providing an intermediate programmed device between a Host and a Guest in a software scheduling mode to allow the Guest virtual machine to access the physical GPU in the Host, wherein the physical GPU can control the number of the virtual GPUs in an API access mode, and recycling and recombination of resources are achieved.

The description is mainly directed to the unified transport protocol module.
The unified transmission protocol module of the virtual desktop platform provided by the embodiment of the invention is divided into three levels in the architectural design: service layer, abstraction layer, and delivery layer, see fig. 3.
The service layer classifies and manages different virtual objects according to different virtualization types, and can specifically manage virtual machines, containers and other self-defined virtualization objects, and adaptation conversion is performed between the service layer and the abstraction layer according to a standard PAI interface.
The abstraction layer provides standard operational services to the virtualized objects and is responsible for protocol communications between the service layer and the delivery layer.
The delivery layer provides different delivery modes according to different virtualization types, can provide delivery of the virtual machine desktop and the container, and adopts unified API access for different delivery modes. And uniformly abstracting the desktop and the container into virtual objects at the client side for uniform delivery. And the delivery layer and the abstraction layer are subjected to adaptation conversion according to a standard PAI interface. The delivery layer automatically detects the protocol type and automatically establishes a protocol channel.
The design mode of multilayer architecture, multiple virtual communication channels and automatic reconnection disconnection is adopted.

The following description is only directed to the functional implementation of the virtual desktop management module.
1. Virtual machine lifecycle management
The virtual desktop management module can assist a user to collect, utilize and manage various resources, and realize efficient use and safety of physical resources. The virtual machine life cycle management operations such as creating, deleting, restarting, viewing, shutting down, creating a snapshot, migrating, mounting a volume, modifying configuration (CPU, memory and disk) and the like are supported.
2. Desktop pool management
The virtual desktop supports the creation, deletion, restoration and reconstruction of a desktop pool, supports basic and strategy configuration, improves the usability of the desktop pool, and can more quickly and uniformly manage the desktop.
Basic management
Desktop pool creation: after the first template is successfully created, guiding a user to enter a prompt window for creating a desktop pool, wherein the desktop pool creation comprises two steps: configuration "basic information" and "configuration policy".
Deleting the desktop pool: and starting a desktop pool deleting task, and if a virtual machine exists in the desktop pool, prompting an administrator by the system and failing to delete the desktop pool.
And (3) desktop pool reduction: and starting a desktop pool restoration task, restoring all the virtual machines in the desktop pool to the state during creation, and being suitable for clearing the user data of all the virtual machines and keeping the state of all the virtual machines during creation.
Rebuilding a desktop pool: and starting a desktop pool reconstruction task, if the virtual machines in the desktop pool are deleted, re-creating the virtual machines, wherein the desktop pool reconstruction task is suitable for updating the scenes of all the virtual machines when the templates of the desktop pool are changed.
Basic configuration of desktop pool
The basic information of the desktop pool includes:
desktop pool name: globally unique desktop pool names;
selecting a template: selecting a desktop template for the desktop pool, based on which all desktops in the desktop pool are to be created;
selecting network resources: by default using the network resources configured at system initialization, the user can also specify specific network resources for each desktop pool.
The following steps are described: description information of the desktop pool;
virtual machine name prefix: the virtual machine name consists of a prefix part and a suffix part, and prefix names of all desktop virtual machines in the desktop pool are input at the prefix part;
virtual machine name suffix: the suffix name of the desktop virtual machine in the desktop pool is composed of numerical numbers, the numerical numbers are increased in sequence, and the initial number is input.
Memory: the method includes the steps that when each desktop virtual machine in a desktop pool is created, allocated memory resources;
number of virtual machine CPUs: the method includes the steps that when each desktop virtual machine in a desktop pool is created, the quantity of CPU resources is distributed;
number of cores per CPU: the number of cores of the CPU allocated to each desktop virtual machine is referred, and the number of vCPUs of the virtual machine is equal to the number of the CPUs of the virtual machine multiplied by the number of the cores of each CPU;
peripheral redirection: peripheral redirection includes two types, RDP resource redirection (hard disk, printer, data port, smart card) and USB device redirection (other USB devices).
Desktop pool policy configuration
Maximum number of created virtual machines: the system guarantees that the total number of the desktop virtual machines in the desktop pool does not exceed the value when the desktop pool is automatically issued. The maximum number of desktop virtual machines that a desktop pool can actually create is also limited by system capacity and storage capacity.
Number of pre-created virtual machines: the number of the unallocated desktop virtual machines maintained for the desktop pool is not greater than the maximum number of the created virtual machines, on the premise that system resources allow.
Desktop pool types: the type of the desktop virtual machine in the desktop pool is set, and all desktops in the public desktop pool are public desktops; the desktops in the special desktop pool are all special desktops.
For the common desktop pool, a recovery strategy and a redistribution strategy of the desktop virtual machine can be configured:
and (4) recovering after logout: when the user logs off and logs in, the virtual desktop is recovered. Shutdown and restart events also trigger logout events, resulting in the system recovering the desktop.
Manual recovery: when a user logs out of a desktop and a server is restarted, the system does not recover the desktop virtual machine, and only the virtual machine can be manually deleted or restored by plan scheduling or an administrator.
Shutdown and recovery of the server: the server has the events of once shutdown, restart or power-off restart, and the server recovers the public desktop when starting.
Desktop redistribution: when the free desktops of the desktop pool are insufficient, the system may assign desktops in the "unregistered" state to other users.
Reduction: the method is to restore the virtual machine to a snapshot point during creation to become a free virtual machine or an unregistered virtual machine of the desktop pool.
3. Backup management
The virtual desktop needs to support the backup restore operation of the virtual machine based on the snapshot, and mainly has the following functions.
The hot standby and the cold standby are simultaneously supported, so that not only is the system backup of the virtual machine in a shutdown state supported, but also the real-time backup of the virtual machine in an operating state is supported.
The virtual machine backed up on one node can be restored not only on the node but also on any node in the cluster.
The backup state is monitored in real time, and when the virtual machine system is backed up, the backup state can be monitored in real time through the log, so that the problems can be conveniently recorded and checked.
The method supports a multi-compression backup algorithm, the data backup requires to support three items of no compression, LZO (quick) and GZIP (good), "no compression" means backup without any compression mode, LZO (quick) "means compression by adopting an LZO mode during backup, the mode has the advantage of being capable of performing quick compression, and" GZIP "item means compression by adopting a GZIP mode during backup, the mode has the advantages of high compression ratio and small compressed file, and a user can select a proper mode to perform virtual machine backup according to own requirements.
The virtual desktop needs to support two backup modes, namely, automatic backup is carried out in a planned mode, and a user can select a corresponding time node to enable the system to execute backup operation; secondly, manual backup is performed, and a user needs to perform backup operation by himself. The automatic backup is also called a scheduled backup, and in this backup mode, an administrator user can set a corresponding virtual machine to perform batch automatic backup through setting. The operation and maintenance personnel only need to select the automatic backup time, the virtual machine to be backed up, the storage mode of the backup file and the compression mode of the backup file. The manual backup is as the name implies that an operation and maintenance person selects a backup function by himself to enable a single virtual machine to be backed up immediately, and in such a backup mode, a user only needs to select information such as a storage position of a backup file, a compression mode of the backup file and the like, so that the instantaneity is very high.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
