XML配置文件示例

概述

本节给出两个基本的虚拟机XML配置文件示例，供用户参考。

示例一

一个包含基本元素的XML配置文件，其内容示例如下：

  1. <domain type='kvm'>
  2.     <name>openEulerVM</name>
  3.     <memory unit='GiB'>8</memory>
  4.     <vcpu>4</vcpu>
  5.     <os>
  6.     <type arch='aarch64' machine='virt-4.0'>hvm</type>
  7.     <loader readonly='yes' type='pflash'>/usr/share/edk2/aarch64/QEMU_EFI-pflash.raw</loader>
  8.     <nvram>/var/lib/libvirt/qemu/nvram/openEulerVM.fd</nvram>
  9.     </os>
  10.     <features>
  11.     <acpi/>
  12.     <gic version='3'/>
  13.     </features>
  14.     <cpu mode='host-passthrough'>
  15.         <topology sockets='2' cores='2' threads='1'/>
  16.     </cpu>
  17.     <iothreads>1</iothreads>
  18.     <clock offset='utc'/>
  19.     <on_poweroff>destroy</on_poweroff>
  20.     <on_reboot>restart</on_reboot>
  21.     <on_crash>restart</on_crash>
  22.     <devices>
  23.     <emulator>/usr/libexec/qemu-kvm</emulator>
  24.     <disk type='file' device='disk'>
  25.         <driver name='qemu' type='qcow2' iothread="1"/>
  26.         <source file='/mnt/openEuler-image.qcow2'/>
  27.         <target dev='vda' bus='virtio'/>
  28.         <boot order='1'/>
  29.     </disk>

  34.         <target dev='sdb' bus='scsi'/>
  35.         <boot order='2'/>
  36.     </disk>
  37.     <interface type='bridge'>
  38.         <source bridge='br0'/>
  39.         <model type='virtio'/>
  40.     </interface>
  41.     <console type='pty'/>
  42.         <video>
  43.            <model type='virtio'/>
  44.         </video>
  45.         <controller type='scsi' index='0' model='virtio-scsi'/>
  46.     <controller type='usb' model='ehci'/>
  47.     <input type='tablet' bus='usb'/>
  48.     <input type='keyboard' bus='usb'/>
  49.     <graphics type='vnc' listen='0.0.0.0' passwd='n8VfjbFK'/>
  50.     </devices>
  51. </domain>
