1. patch合入后，oemaker编译成功
2. patch分析
```
- virtinstall: split no_install conditional apart to track code coverage
  完善测试用例，覆盖遗漏的场景

- virtinstall: fix regression with --boot and no install method
  修复boot选项的隐藏含义（Resolves: https://github.com/virt-manager/virt-manager/issues/426）

- tests: Add a compat check for linux2020 in amd-sev test case
  增强测试的兼容性，避免使用较旧的 osinfo-db，以致 amd-sev 测试失败。

- cli: --cpu: Add maxphysaddr.{mode,bits} options
  增加了对 cpu 物理地址位控制的支持，这对于具有大量 ram 的 VM 非常有用。

- virt-install: --help required options are wrong
  回显的帮助说明，没有必要显示与其他参数的关联
  合入该补丁前
  [root@b06-vm ~]# virt-install --install
  usage: virt-install --name NAME --memory MB STORAGE INSTALL [options]
  virt-install: error: argument --install: expected one argument
  合入该补丁后
  [root@b06-vm SPECS]# virt-install --install
  usage: virt-install OPTIONS
  virt-install: error: argument --install: expected one argument

- cloner: Sync and system uuid
  解决克隆同时带有sysinfo和uuid虚机时，出现sysinfo与uuid不匹配的问题（https://bugzilla.redhat.com/show_bug.cgi?id=2038040）

- virt-install: --unattended and --cloud-init conflict
- virt-install: Reuse cli.fail_conflicting
  以上两个修改，解决--unattended and --cloud-init两个参数冲突问题
   （https://bugzilla.redhat.com/show_bug.cgi?id=2117157）

- cli: support --boot loader.stateless=
  默认虚拟机会生成指定的nvram，用于支持虚拟机的启动
  <os>
    <type arch='x86_64' machine='pc-i440fx-8.2'>hvm</type>
    <loader readonly='yes' type='pflash'>/usr/share/edk2/ovmf/OVMF_CODE.fd</loader>
    <nvram template='/usr/share/edk2/ovmf/OVMF_VARS.fd'>/var/lib/libvirt/qemu/nvram/kylin-hostos10.0_VARS.fd</nvram>
    <boot dev='hd'/>
  </os>

通过增加stateless的支持，允许在不创建nvram的场景下启动虚机;支持多个虚拟机共用edk2提供的uefi固件
  <os>
    <type arch='x86_64' machine='pc-i440fx-8.2'>hvm</type>
    <loader readonly='yes' type='pflash' stateless='yes'>/usr/share/edk2/ovmf/OVMF_CODE.fd</loader>
    <boot dev='hd'/>
  </os>

- diskbackend: Drop support for sheepdog
  sheepdog是一种分布式文件系统，也是存储池类型的一种。
  libvirt-8.8已经移除libvirt-daemon-driver-storage-sheepdog，因此丢弃它
