Virtual machine migration detection by hosted operating system
In one embodiment, a guest operating system (OS) running on a virtual machine (VM) detects VM migration, where the embodiment includes storing, by the guest OS, a VM identifier (VMID) provided by the VM and a first host identifier (HID) provided by a host computer system in computer memory. The embo...

| description | In one embodiment, a guest operating system (OS) running on a virtual machine (VM) detects VM migration, where the embodiment includes storing, by the guest OS, a VM identifier (VMID) provided by the VM and a first host identifier (HID) provided by a host computer system in computer memory. The embodiment also includes determining, by the guest OS, that the VM performs the migration that is transparent to the guest OS. The embodiment also includes detecting, by the guest OS, that the VM has been migrated based on a comparison of the first HID to a second HID provided to the guest OS in response to an HID request from the guest OS.
在一个实施例中，在虚拟机(VM)上运行的访客操作系统(OS)检测VM迁移，其中该实施例包括由访客OS将VM提供的VM标识符(VMID)和主机计算机系统提供的第一主机标识符(HID)存储在计算机存储器中。该实施例还包括由访客OS确定VM执行对访客OS透明的迁移。该实施例还包括由访客OS基于第一HID与响应于来自访客OS的HID请求而提供给访客OS的第二HID的比较来检测VM已经被迁移。 |
