Therefore, the tenant's VM can no longer rely on the DHCP service for VM failure recovery
It can be seen that the above-mentioned VM fault recovery method cannot perform fault recovery on the VM in the scenario of no DHCP service

Abstract

A fault recovery method and device for a virtual machine, the method comprising: when it is detected that an original virtual machine has failed, using an image template to create a new virtual machine (101); setting the MAC address of the original virtual machine to the MAC address of the new virtual machine, and mounting the data disk of the original virtual machine to the new virtual machine (102); and starting the new virtual machine (103), wherein when the data disk in the new virtual machine is partitioned, the reservation area where the service data in the data disk is located is not formatted. The method can be used to troubleshoot a VM under no DHCP service scenario.

Description

technical field [0001] The present invention relates to the field of virtual technology, in particular to a virtual machine failure repair method and device. Background technique [0002] With the development of virtual technology, virtual machines (Virtual Machine, VM) are currently more and more widely used. However, a system disk failure may occur during the running of the VM, for example, the system disk failure of the VM is caused by a guest operating system (Guest Operation System, Guest OS). And when the VM system disk fails, the VM cannot work normally, resulting in business damage. The current solutions for dealing with VM faults mainly use the following methods: [0003] After the VM fails, the VM is set to boot from the network, and applies for an IP from the Dynamic Host Configuration Protocol (DHCP) server, and the VM uses the applied IP to connect to the Trivial File Transfer Protocol (TFTP) server to download the micro Operating system (micro OS); the VM st...
