Virtualization causes an increase in the amount of physical memory required due to the extra memory needed by VMware Cloud on AWS for its own code and for data structures.
VMware Cloud Director 9.7부터 시스템 관리자는 Flex 할당 모델을 사용하여 조직 VDC(가상 데이터 센터)를 생성할 수 있습니다. 시스템 관리자는 Flex 할당과 VM 크기 조정 정책을 조합하여 VDC 및 개별 VM(가상 시스템) 수준 모두에서 CPU 및 RAM 소비를 제어할 수 있습니다. Flex 할당 모델은 기존 할당 모델에서 사용할 수 있는 모든 할당 구성을 지원합니다. VMware Cloud Director 10.0 이상에서는 Flex가 아닌 모든 조직 VDC를 Flex VDC로 변환 ...
Virtualization of memory resources has some associated overhead. ESXi virtual machines can incur two kinds of memory overhead. ESXi memory virtualization adds little time overhead to memory accesses. Because the processor's paging hardware uses page tables (shadow page tables for software-based approach or two level page tables for hardware-assisted approach) directly, most memory accesses in the virtual machine can execute without address translation overhead. The memory space overhead has two components. ...

Prerequisites ; Power off the virtual machine. ; Verify that the virtual machine has a guest operating system that supports memory hot add capabilities. ; Verify that the virtual machine compatibility is ESXi 4.x and later. ; Verify that VMware Tools is installed.
Field, Description ; PMEM (MB), Displays the machine memory statistics for the server. All numbers are in megabytes. total Total amount of the machine memory in the server. vmk Amount of the machine memory being used by the ESXi VMkernel. other Amount of the machine memory being used by everything other than the ESXi VMkernel. free Amount of the machine memory that is free. ; VMKMEM (MB), Displays the machine memory statistics for the ESXi VMkernel. All numbers are in megabytes. managed Total amount of the machine memory managed by the ESXi VMkernel. min free Minimum amount of the machine memory that the ESXi VMkernel aims to keep free. rsvd Total amount of the machine memory currently reserved by resource pools. ursvd Total amount of the machine memory currently unreserved. state Current machine memory availability state. Possible values are high, soft, hard and low. High means that the machine memory is not under any pressure and low means that it is. ; NUMA (MB), Displays the ESXi NUMA statistics. This line appears only if the ESXi host is running on a NUMA server. All numbers are in megabytes. For each NUMA node in the server, two statistics are displayed: The total amount of machine memory in the NUMA node that is managed by ESXi . The amount of machine memory in the node that is currently free (in parentheses). Shared memory for the ESXi host might be larger than the total amount of memory if memory is over-committed.
