Hot-Add Memory in Linux (SUSE11)

After using VMware vcenter5.5 to dynamically add memory to SuSE 11, use Free-m view to discover that there are no changes to the virtual machine memory.

Check the information, found that under the SUSE11, you need to load the dynamic Add Memory module, and then operate as follows:

# modprobe acpiphp# modprobe acpi-memhotplug# grep-v online/sys/devices/system/memory/*/state

Description: The ACPOHHP module is a module for detecting hot-add devices, and Acpi_memhotplug is a hot-add module.

If you have memory offline, use echo online >/sys/devices/system/memory/memory[number]/state to bring it online

in addition, I tested the CentOS6 memory dynamic Add, directly on the vcenter add, in the system can be directly recognized.
