28.1 Adding and Removing CPUs Edit source

Some virtualization environments allow adding or removing CPUs while the virtual machine is running.

For safe removal of CPUs, first deactivate them by executing

root # echo 0 > /sys/devices/system/cpu/cpuX/online

Replace X with the CPU number. To bring a CPU back online, execute

root # echo 1 > /sys/devices/system/cpu/cpuX/online
