Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The core idea of the invention is as follows: introducing a pre-boot eXecution Environment (PXE, also called pre-eXecution Environment) technology, establishing a shared single disk image for a virtual machine in a system by using diskless software, and setting a first boot mode of the virtual machine in the system as PXE network boot. Therefore, through the management of the single disk image of the virtual machine, when the operating system and the application program are upgraded, only the patch of the system and the update of the application program need to be carried out on the single disk image, and each virtual machine sharing the disk image can trigger the streaming technology to immediately update the single disk image to the virtual machine by utilizing the PXE network as long as the machine is started or restarted. Therefore, the system patch and the application software can be updated on line in real time, and the management workload and the operation and maintenance cost of the super-fusion system are greatly reduced.
Fig. 1 is a schematic flow chart of a virtual machine deployment method of a hyper-fusion system according to an embodiment of the present invention, as shown in fig. 1, the embodiment mainly includes:
The present step is used to create a diskless server in the super-fusion system, and specifically, the diskless server may be created directly by using the whole hardware resource of the selected physical server node, or may be created by using only one virtual machine created on the node. Preferably, the diskless server can be created by the following two methods:
the method comprises the steps that a preset server operating system is installed on a physical server node; and installing diskless software on the physical server node.
And secondly, installing a preset server operating system on one virtual machine of the physical server node, and installing diskless software on the virtual machine.
In the second method, the server is created by using one virtual machine created on the selected physical server node, so that resources of the physical server node can be saved compared with the first method.
In this step, for the selection of the physical server node, any one node in the system may be selected, or may be specified in advance by a system administrator according to actual needs.
In the above method, no matter the diskless server is created on the physical server node or the diskless server is created on the virtual machine, the specific creation method can be implemented by using the prior art, and is not described herein again.
This step is used to create a disk image template, which will be shared by the virtual machines in the system.
Preferably, this step can be implemented by the following method:
creating a virtual machine in any physical server node in the system, and installing the operating system on the virtual machine, wherein the installation comprises installation of a driver, a system patch and application software.
In the method, a designated operating system needs to be installed in one virtual machine in the system, and the installed file forms the disk image template.
Here, the operating system to be installed may be set according to the operating system to be used in the actual virtual machine.
This step is used to copy the disk image template created in step 102 to the diskless server, so that the disk image template can be obtained from the diskless server when a virtual machine in the system is started.
Here, it is required to create storage configuration parameters on the diskless server through the diskless management interface, where the storage configuration parameters at least include: a storage directory, a write-back directory, and a mirror file name. Then, the disk image template created in step 102 is saved to the file corresponding to the configured image file name.
Preferably, the disk image template may be saved in the diskless server by the following method:
establishing a virtual machine on the diskless server, and associating the virtual machine with the mirror image file name and the network card MAC address of the virtual machine; and storing the disk mirror image template into a file corresponding to the mirror image file name.
And step 104, when a virtual machine is newly established in the system, setting the first starting mode of the virtual machine as PXE network starting.
It should be noted that PXE is a technology developed by Intel corporation, works in a Client/Server network mode, supports a workstation to download an image from a remote Server through a network, and thus supports starting an operating system through the network, during the starting process, a terminal requests the Server to allocate an IP address, and then downloads a start software package to a local memory for execution by using TFTP or MTFTP protocol, and the start software package completes the setting of the terminal basic software, thereby booting the terminal operating system pre-installed in the Server. PXE can boot a variety of operating systems, such as: windows95/98/2000/Windows2003/Windows2008/winXP/win7/win8, linux, etc.
In this step, the first starting mode of the virtual machines in the system needs to be set as a PXE network starting mode, so that when each virtual machine is started, the disk image template is directly triggered to be downloaded from the diskless server, and the disk image template enters the desktop system of the corresponding version. Therefore, when the system is maintained, the virtual machines in the system can use the upgraded operating system and application software only by upgrading the disk image template in the diskless server. For example, if the disk image template is used by 200 virtual machines, the 200 virtual machines are restarted or restarted, and the real-time online update of system subscription and application software is realized. Therefore, the virtual machine deployment method of the embodiment is beneficial to improving the updating efficiency of the super fusion system and greatly reducing the management workload and the operation and maintenance cost of the super fusion system.
In addition, in the above embodiment, by creating the diskless server, the technology that the diskless system writes back to the memory of the workstation can be utilized, so that the user does not need to pay attention to the pressure of the stored input and output on the virtual desktop, and a 10GB network can quickly start the desktop system for 10 seconds, thereby greatly reducing the storage performance requirement of the physical server node.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
