When starting, the CHARON-VAX software checks the available number of host CPU cores. Currently, this check is based on the maximum number of VAX CPUs that can be emulated, not on the number of the actually configured VAX 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-VAX will issue a warning message even if the requirements for the configured number of VAX CPUs are fulfilled. The CHARON-VAX software will work despite this warning if the requirements for the configured number of VAX CPUs are fulfilled.

Hyperthreading must be switched off completely. Disable hyperthreading 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 Hyperthreaded Core Sharing mode to None. |
