Ha. I found out that the VMware vitrual Machine has a standard setting that uses only one CPU core... When trying to raise this to 6, it tells me that I need to upgrade. I can change it to 4, and it seems to re-initiate. But no difference in CPU usage.
Only after completely rebooting Virtual Machine and Ubuntu in it, I could use 4 (out of
cores and can now mine with 50% CPU 
Still not sure if I am actually mining correctly.
Hope this helps someone...

Which VMWare version are you using?
I am using 9.0.2 build-1031769 it supports all 8 cores, I advise upgrading it.
Thanks. Strange, I freshly downloaded vmware player and installed it 3 hours ago, but it is version 5.0.2 build-1031769 ?!
Got it from https://my.vmware.com/web/vmware/free#desktop_end_user_computing/vmware_player/5_0 , where did you get the 9.0.2 version?
