linux - 如何使用 VMX 挂起和恢复 VM

Question

我已经在 Linux 中用 VMX 开发了一个玩具管理程序，它可以很好地与我的测试 VM 一起工作。现在我正在尝试使用我的玩具管理程序测试暂停和恢复我的测试 VM。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。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 的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 加载程序，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。然后通过调用“vmlaunch”告诉管理程序启动虚拟机。 (在此之前，管理程序将调用 vmxon、vmclear、vmptrld 和 vmwrite VMCS 字段和客户 CPU 上下文)。我的期望是 VM 将从之前保存的 RIP 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。请照亮它。

Answer 1

FS ATTR 和 GS ATTR 无效。请参阅 26.3.1.2 中“访问权限字段”的检查。如果第 16 位为 0，则第 7:0 位必须为非零，通常为 0x93。
