我已经在 Linux 中使用 VMX 开发了一个玩具虚拟机管理程序，它可以与我的测试 VM 很好地配合使用。现在我正在尝试使用我的玩具虚拟机管理程序来测试挂起和恢复我的测试虚拟机。我执行了以下操作来暂停虚拟机。
VM 以实模式启动，然后进入保护模式。它调用 wrmsr，这将导致 VMEXIT。虚拟机管理程序获取 VMEXIT，然后将 CPU 上下文(gprs、段寄存器、描述符表等)和 VM 内存保存到磁盘文件中，然后退出。 (VMXON/VMCS 区域未清除)。
现在，重新启动VM加载器，它将读取磁盘文件，将CPU上下文保存到VMCS字段中，并填充VM的内存。然后告诉虚拟机管理程序通过调用“vmlaunch”启动虚拟机。 (在此之前，虚拟机管理程序将调用 vmxon、vmclear、vmptrld 和 vmwrite VMCS 字段和 guest CPU 上下文)。我的期望是虚拟机将从之前保存的 RIP 中恢复。
但它因“无效的 guest 状态”而失败
下面是 WRMSR VMEXIT 处的 VMCS 转储。

我用 ch 26.3 检查了字段，但找不到任何提示。 请用你的灯照亮它。
最佳答案
FS ATTR 和 GS ATTR 无效。请参见第 26.3.1.2 节中“访问权限字段”的检查。如果位 16 为 0，则位 7:0 必须非零，通常为 0x93。
