[模板] KVM 虚拟机的 XML 模板

注意：

此模板只用于参考

# vi /etc/libvirt/qemu/template_centos_7_10g.xml

创建以下内容：

<domain type='kvm'>
  <name>node</name>
  <memory unit='KB'>1524000</memory>
  <currentMemory unit='KB'>1524000</currentMemory>
  <vcpu placement='static'>1</vcpu>
  <os>
    <type arch='x86_64' machine='template_centos_7_10g'>hvm</type>
    <boot dev='hd'/>
    <bootmenu enable='yes'/>
    <bios useserial='yes'/>
  </os>
  <features>
    <acpi/>
    <apic/>
  </features>
  <cpu mode='host-passthrough'>
  </cpu>
  <clock offset='localtime'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>restart</on_crash>
  <devices>
    <emulator>/usr/bin/qemu-kvm</emulator>
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2'/>
      <source file='/var/lib/libvirt/images/template_centos_7_10g.img'/>
      <target dev='vda' bus='virtio'/>
    </disk>
    <interface type='bridge'>
      <source bridge='vlan001'/>
      <model type='virtio'/>
    </interface>
    <channel type='unix'>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
    </channel>
    <serial type='pty'></serial>
    <console type='pty'>
      <target type='serial'/>
    </console>
    <memballoon model='virtio'></memballoon>
  </devices>
</domain>

（补充：这里以给 template_centos_7_10g 创建一个虚拟机模板为例）
