When starting, the CHARON-AXP software checks the available number of host CPU cores. Currently, this check is based on the maximum number of AXP CPUs that can be emulated, not on the number of the actually configured AXP CPUs. Therefore the number of host CPU cores recommended for the maximum number of emulated CPUs - as shown in the right column of the table above - must be available. If the available number of host CPU cores is below this number, CHARON-AXP will issue a warning message even if the requirements for the configured number of AXP CPUs are fulfilled. The CHARON-AXP software will work despite this warning if the requirements for the configured number of AXP CPUs are fulfilled.

Note

Hyper-threading must be switched off completely. Disable hyper-threading in the BIOS settings of the physical host or, for a VMware virtual machine, edit the virtual machine properties, select the Resources tab then select Advanced CPU. Set the Hyper-threaded Core Sharing mode to None.
