Walkthrough

在 KVM 虚拟机启动流程中引入了新的 guestOsType 参数。在 KVMAgentCommands.StartVmCmd 中添加了灰度版本字段，并在 KVMHost.startVm() 方法中将虚拟机配置的客户机操作系统类型传播到代理命令。

Changes

Cohort / File(s)	Summary
KVM 代理命令 plugin/kvm/src/main/java/org/zstack/kvm/KVMAgentCommands.java	在 StartVmCmd 类中添加了灰度版本字段 guestOsType（注解为 @GrayVersion("5.5.12")）以及对应的公开访问器方法 getGuestOsType() 和 setGuestOsType(String)。
KVM 主机启动流程 plugin/kvm/src/main/java/org/zstack/kvm/KVMHost.java	在 startVm() 方法中调用 cmd.setGuestOsType()，将虚拟机的客户机操作系统类型从 spec.getVmInventory().getGuestOsType() 传播到启动命令。

Poem

🐰 一只灰色的字段悄然降临，
从虚拟机的清单跳跃而出，
飞过 KVM 的通道，
告诉代理系统的灵魂，
这只兔子说：「客户机已识别！」✨
