Only single CPU core detected in BT4 VMWare edition

[blackhathacker]

I've just fired up the VMWare version of BT4 Final and set about cracking my test wlan (WPA) at home. I've noticed (via the performance monitor and x86info) that only a single CPU core is seen by BT. I want to utilise all four cores in aircrack-ng.

The host in question is a quad-core Q6600, and the .vmx config file shows maxvcpus = "4".

Grateful for any pointers.

Use setting from vmware. If you want to use whole power of your computer use USB stick or HDD installed version of BT4. BT4 is 32bit so it may not can use whole power of your computer.

You can install 64 bit version of some linux, like ubuntu, and install aircrack-ng there, but here is no support for that. Thats how you will get most power out fo your computer.

Worked it out. Need to change maxvcpus = "4" to numvcpus = "4" in the .vmx config file.

VMWare Player limits to 2 virtual CPUS.
