发明名称 Selecting Between Pass-Through and Emulation in a Virtual Machine Environment
摘要 According to one or more embodiments a logical virtual device may provide the desired functionality using either a virtual device or a physical device connected to a virtual machine. When the physical device is available, a guest operating system executing on a virtual machine (VM) can be instructed to utilize the physical device. When the VM is migrated between hosts of different underlying hardware, or when the physical device becomes unavailable, e.g., through dynamic reconfiguration or reallocation of physical resources, the guest operating system can be instructed to utilize the virtual device instead.
