in short, the EM thread is the 'emulation thread' which emulates one guest CPU. One EM thread per guest CPU, so if your guest has 4 CPUs configured, your VM process will create 4 EM threads. The threads of a VM process are scheduled by the host. Kind regards, Frank -- Dr.-Ing. Frank Mehnert | Software Development Director, VirtualBox ORACLE Deutschland B.V. & Co.
