Many servers in the data center perform xen virtualization. Suddenly, the memory size detected by free-M differs greatly from the actual memory size of the server .. I found a lot of information and compared several virtualized servers to find the kernel problems after virtualization. * ***** If the actual memory of the server is less than or equal to 32 GB, after xen virtualization, the host memory plus
