I was very pleasantly surprised when TP Beta 2 installed on openSUSE 12. kernel 3.5 "out of the box". When I tried to create a guest (Linux Mint) and powered on I got the same kiind of panic as used to happen on Fedora with WS 8. Tried to change processor preference from autoomatic to binary but that didn't help. paniced again I seemed to recall other entries s in the vmx that might help - but I forget where and what they are.
Any suggestions?
