Memory Swap Partition Status: Select whether to enable the memory swap partition. After this function is enabled, deficient memory usage can be compensated by creating disk partitions.
Memory Compression: Select whether to enable memory compression. Once this feature is enabled, the swap partition compresses data, creating a compressed memory pool that occupies a certain percentage of the host memory. Enabling memory compression allows the host to store more data. You can select a compression level, including low, medium, and high, representing 20%, 30%, and 40% of the total host memory, respectively.
Shared Memory Page Status: Select whether to enable shared memory pages. Shared memory pages allow the kernel to share identical memory pages among multiple processes (including VMs). Enabling this feature can reduce the actual memory usage of each VM. This allows more VMs to be created on a physical host, increases VM density, and improves physical resource utilization.
VM: Set the memory isolation value of the VMs. When the total memory used by all online VMs exceeds the limit, the performance of the VMs will decrease.
OVS: Set the memory isolation value of the virtual switch. When the total memory used by all virtual switches exceeds the limit, the performance of the virtual switches will decrease.
