Problems solved by technology

The connection channel between the direct-attached storage and the server host is usually connected by iSCSI. As the processing power of the server CPU becomes stronger, the storage hard disk space becomes larger, and the number of hard disks in the array increases, the iSCSI channel will Become an IO bottleneck; the iSCSI ID resource of the server host is limited, so the number of iSCSI channel connections that can be established is limited
Finally, DAS storage cannot effectively support high availability (High Availability, HA) and live migration, which brings great suffering to the need to perform live migration of virtual machines between nodes according to the load balancing strategy

Embodiment 1

[0049] ginseng Figure 1 to Figure 7A specific implementation manner of a method for starting a virtual machine based on the PXE protocol (hereinafter referred to as the "method") of the present invention is shown.

[0050] In the traditional PXE service, when the client starts, it will uniformly send a broadcast packet to obtain the DHCP information and the system boot program in the TFTP service, and then load the system image stored on the shared file server according to the address in the system additional file. In the existing technology, multiple DHCP servers are not allowed in the same network environment, so in the case of high concurrent requests, the single-point PXE service will encounter the problem of heavy pressure and slow response, resulting in a long time for the virtual machine to start , the loading system is slow. At the same time, since it is a single-point PXE server, if the service fails, all virtual machines under the same network will fail to start. ...

Embodiment 2

[0081] ginseng Figure 8 As shown, this embodiment also discloses an electronic device 500, which includes:

[0082] A processor 51 , a storage device 52 composed of at least one storage unit, and a communication bus 53 establishing a communication connection between the processor 51 and the storage device 52 . The processor 51 is configured to execute one or more programs stored in the storage device 52, so as to implement the method for starting a virtual machine based on the PXE protocol as disclosed in the first embodiment.

[0083] Specifically, the storage device 52 may be composed of a storage unit 521 to a storage unit 52j, wherein the parameter j is a positive integer greater than or equal to 1. Processor 51 may be ASIC, FPGA, CPU, MCU or other physical hardware or virtual device with instruction processing function. The form of the communication bus 53 does not need to be specifically limited, I 2 C bus, SPI bus, SCI bus, PCI bus, PCI-E bus, ISA bus, etc., and can...

Abstract

The invention relates to the technical field of computers, and provides a PXE protocol-based virtual machine starting method and electronic equipment, and the method comprises the steps: matching a mirror image virtual network for a virtual machine to establish communication with a TFTP server through a mirror image virtual network scheduler; after a virtual machine starting instruction is received, selecting an idle virtual host by the mirror image virtual network scheduler, selecting a unique TFTP server according to the resource overhead of the candidate TFTP server, configuring a mirror image virtual network corresponding to the finally selected TFTP server for the virtual machine, and starting a PXE protocol to start the virtual machine. According to the invention, the virtual machine in the virtual host in the high-availability virtualization cluster can be flexibly created and thermally migrated, and the timeliness and reliability of service response are ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method for starting a virtual machine based on the PXE protocol and electronic equipment. Background technique [0002] In order to reduce the impact of physical machine downtime on virtual hosts, virtual hosts are usually deployed in cluster mode, and FC-SAN, NFS, or iSCSI are used between each node of the cluster to implement shared distributed storage. The applicant pointed out that the deployment and operation costs of deploying and running the virtual host are relatively high, and it is not suitable for a small network application environment. However, although DAS storage can achieve high cost performance, while DAS storage brings a simple architecture, the direct connection mode also makes it very difficult to increase storage capacity, and there is a very high post-management cost. [0003] At the same time, DAS storage (direct-attached storage) relies more o...
