Description
Technical Field
The invention relates to the technical field of cluster management, in particular to a VirtualBox-based cluster management system.
Background
VirtualBox is an open source cross-platform virtualization suite developed by Sun, Inc., primarily used to provide desktop virtualization capabilities on the x86 platform. The VirtualBox is called as the strongest free virtual machine software, and not only has rich characteristics, but also has excellent performance.
First, the VirtualBox is simple and easy to use, and the virtualizable system includes Windows (from Windows 3.1 to Windows10, Windows Server 2012, all supported by Windows systems), Mac OS X, Linux, OpenBSD, Solaris, IBM OS2, and even Android operating systems. The user can install and run these operating systems described above on the VirtualBox. Second, VirtualBox is unique in that it includes Remote Desktop Protocol (RDP), iSCSI, and USB support, as compared to VMware and Virtual PC of the same nature. Moreover, after installing the VirtualBox Extension Pack, the VirtualBox already implements support for the hardware device of USB 2.0 on the client operating system.
The VirtualBox is capable of installing multiple client operating systems, each of which can be independently started, paused and stopped. The main end operating system and the client end operating system can communicate with each other, and the environment that a plurality of operating systems run simultaneously can use a network simultaneously.
Since VirtualBox is mainly directed to individual desktop users, efforts have been made to optimize the virtualized desktop, and since it is free, it has developed rapidly in recent years.
Hypervisors are an intermediate software layer that runs between a physical server and an operating system, allowing multiple operating systems and applications to share a set of underlying physical hardware, and thus can also be viewed as a "meta" operating system in a Virtual environment that coordinates access to all the physical devices and Virtual machines on the server, also known as Virtual machine monitors (Virtual machine monitors). Hypervisor is the core of all virtualization technologies. The ability to support multi-job load migration without interruption is a basic function of Hypervisor. When the server starts and executes the Hypervisor, it allocates an appropriate amount of memory, CPU, network and disk to each virtual machine, and loads the guest operating systems of all the virtual machines.
Currently, the mainstream hypervisors capable of performing cluster management include Qemu, Zen and VMWare, but a set of cluster management system software management is not available for the VirtualBox which is excellent in performance on a desktop system. If the desktop virtualization capability of the VirtualBox can be uniformly combined with large-scale node and cluster management, a set of VDI solution with good user experience can be provided.
Based on the above situation, the invention provides a VirtualBox-based cluster management system.
Disclosure of Invention

The server is responsible for providing storage, updating and synchronizing the state files, detecting the running state of the local end, receiving the instruction sent by the receiving and managing end and distributing the received instruction to the local end.
Since the VirtualBox supports NFS and CIFS shared storage, the server storage directly uses a network file system to store the virtual machine image.
The VirtualBox-based cluster management system performs synchronization or update operation according to each local end node state file and system state file stored by each server.
According to the VirtualBox-based cluster management system, the local end node state stored by the server is inquired, if the local end node state stored by the server is inconsistent with the actual state of the corresponding local end node, the server is informed to execute the state updating operation, the local end node state stored on each server is ensured to be consistent, and therefore accurate cluster data are provided for users.
And the local end inquires the local end node state stored on each server, if the local end node states stored on the two servers are inconsistent, the data of the servers are synchronized, and the local end is allowed to connect with only one server at the same time.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the embodiment of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
The VirtualBox-based Cluster management system (VBCluster for short) comprises a server side, a management side and a local side, wherein the server side is responsible for node management, state synchronization and storage management, the management side is responsible for user management, Cluster management and upgrade management, and the local side actually controls the VirtualBox and is responsible for command execution and state feedback.
The management end is an entrance for performing VirtualBox cluster management by a user, and can organize a service end and manage a local end node.
The management terminal can be a Web management interface for providing a VirtualBox cluster management entrance, and can also be an App program.
The server is responsible for providing storage, updating and synchronizing the state files, detecting the running state of the local end, receiving the instruction sent by the receiving and managing end and distributing the received instruction to the local end.
Since the VirtualBox supports NFS and CIFS shared storage, the server storage directly uses a network file system to store the virtual machine image.
The server is a VBCluster core component, where the most important functions are status update and synchronization. VBCluster does not judge cluster status from the network as in the mature cluster management systems like corysync.
The VirtualBox-based cluster management system performs synchronization or update operation according to each local end node state file and system state file stored by each server.
According to the VirtualBox-based cluster management system, the local end node state stored by the server is inquired, if the local end node state stored by the server is inconsistent with the actual state of the corresponding local end node, the server is informed to execute the state updating operation, the local end node state stored on each server is ensured to be consistent, and therefore accurate cluster data are provided for users.
And the local end inquires the local end node state stored on each server, and if the local end node states stored on the two servers are inconsistent, the data synchronization of the servers is carried out. Although the local side can access the state information of the two servers, when the state information of the two servers is inconsistent, the local side can only obtain the state information from one server at the same time, that is, the local side can only be in one state at the same time. If the two pieces of state information are acquired simultaneously, the local end cannot judge the state of the local end, and the state information of the server cannot be updated, so that the local end is only allowed to be connected with one server at the same time.
And the local end is responsible for executing the VirtualBox instruction. Due to the perfect functions of the VirtualBox, the VirtualBox can directly manage the virtual machine of the VirtualBox through a command interface provided by the VirtualBox.
Example 1
Taking 6 computers as an example, the VirtualBox-based cluster management system is built, and the specific implementation steps are as follows:
the method comprises the steps of firstly, selecting two computers as shared storage, installing a VBCluster server of the VirtualBox-based cluster management system, simultaneously starting NFS shared storage service, and creating an NFS folder and a VM _ STATE folder. The NFS folder stores VBox virtual machine images on the computing nodes, and the VM _ STATE folder stores cluster STATEs in VBCluster.
The IP of the two server computers are 192.168.100.14 and 192.168.100.24 respectively.
And secondly, taking the rest 4 computers as computing nodes, and installing the VirtualBox and the local end of the VirtualBox-based cluster management system VBCluster. And simultaneously mounting NFS and VM _ STATE folders of a VBCluster server, creating a virtual machine on each computing node, and placing all created virtual machine files under the mounted NFS folders.
And thirdly, installing management terminal software of VBCluster in the virtual machine. And meanwhile, the virtual machine and the server program are configured in the same network segment.
And fourthly, after the environment configuration is completed, running cluster management software to perform cluster state query, modification, virtual machine migration hot standby and other operations.
