Running 8.0.18314 on Lion, everything was fine with several virtualization of CentOS until I had switch to 8.0.18345 then the centOS http://bugs.centos.org/view.php?id=4357 after removal of my cable power from my MacBook. This CentOS issue makes virtual machine no longer usable so I reverted to 8.0.18314 and everything was back to normal.
