摘要
A method for managing a memory of a virtual machine, a physical host, a PCIE device and a configuration method thereof are provided. The method executed by a virtual machine includes: allocating a memory to a service carried on a PCIE device, where the memory includes multiple memory blocks, the multiple memory blocks is used to save working information of the service; generating a base address table BAT and a chip logic address table CLAT, where the BAT includes a CLAT entry base address corresponding to the service, and the CLAT includes a first address of each memory block; and sending an address of the BAT and a function number corresponding to the virtual machine to the PCIE device. Therefore, the PCIE device can obtain, according to the address of the BAT and the function number, working information of a service from the virtual machine.
