Hi @AaronDot. Thanks for your PR.

I'm waiting for a deepin-community member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

sw64 构建失败说明（deepin:CI:TestingIntegration:test-integration-pr-4525）

libvirt 在 sw64 上编译通过，但测试阶段有 3 个用例失败：check-symfile、check-admin-symfile、qemuxml2xmltest。

经排查与本 PR 无关：

• 同一份 PR 源码在 x86_64 / aarch64 / loong64 / riscv64 上这 3 个测试全部通过；
• 失败内容为 GObject class 符号导出缺失（virConnectClass、virAdmClientClass 等）以及 virtio-gpu 视频设备 / PCIe 相关差异，PR 的 8 个补丁均不涉及这些代码路径；
• 属于 sw64 工具链 / 打包层面的既有架构差异，建议单独提单给 sw64 维护排查。

本 PR 本身可以合入。
