In order to add vCPUs, go to the
INSTANCES section and select
RESIZE INSTANCE from the drop-down menu in the instance chosen.
In the window that opens, you will see all available resources (the
OLD FLAVOR item). In the
NEW FLAVOR item, select the instance type with the required number of vCPU cores.
The next step is to confirm the instance type changing.
In the same way, if desired, you can reduce the number of processor cores, if there is no need for large capacities.
