【openEuler-22.03-LTS-SP2】修改虚拟机内核启动参数，Guest-Idle-Haltpoll特性无法生效

【标题描述】x86/arm修改虚拟机内核启动参数，Guest-Idle-Haltpoll特性无法生效
【环境信息】
硬件信息：
1）虚机场景提供虚机XML文件
虚拟机规格：4核 + 4G内存 + 20G存储（安装时只修改了CPU模式，其他选项均使用默认参数）
arm使用鲲鹏物理机装虚拟机, 虚拟机CPU模式为host-passthrough
x86使用海光物理机装虚拟机，虚拟机CPU模式为host-passthrough
2) 虚拟机内核参数
输入图片说明

软件信息：
1)系统版本:openEuler 22.03 (LTS-SP2)
2)内核版本:5.10.0-153.12.0.92.oe2203sp2.x86_64
输入图片说明

【问题复现步骤】
出现概率(100%必现)
1.安装虚拟机，使用openEuler-22.03-LTS-SP2-x86_64-dvd.iso镜像
2.在x86虚拟机内核启动参数中配置“cpuidle_haltpoll.force=Y”启动Guest-Idle-Haltpoll特性。
arm虚拟机在虚拟机内核启动参数中配置“cpuidle_haltpoll.force=Y haltpoll.enable=Y”的方式启动Guest-Idle-Haltpoll特性。
（参照欧拉官方文档链接https://docs.openeuler.org/zh/docs/22.03_LTS_SP2/docs/Virtualization/最佳实践.html）
3.重启虚拟机后，确认Guest-Idle-Haltpoll特性没有生效。

【预期结果】
预期cat /sys/devices/system/cpu/cpuidle/current_driver，应该输出为haltpoll

【实际结果】
输入图片说明

【附件信息】
查询dmesg 信息，有如下提示“Booting kernel: Y' invalid for parameter cpuidle_haltpoll.force'”

请问这个特性存在问题，有哪位负责的同事可以解答一下

方便提供下虚拟机xml吗？

该问题缺少关键信息，暂时先挂起

arm机器的xml如下所示

暂不支持cmdline配置，待更新资料
arm可以在线配置：echo 1 > /sys/module/cpuidle_haltpoll/parameters/force
x86支持在xml中配置：

<domain type='kvm'>
 ...
 <features>
   <kvm>
     ...
     <hint-dedicated state='on'/>
   </kvm>
 </features>
  ...
</domain>
