Right, actually my intension was to refer to the host type not to the CPU type. So even if the host is 32-bit (that is, if it runs a 32-bit kernel) it is possible to run a 64-bit guest on that host if the CPU supports VT-x or AMD-V and it supports the long mode as well. The latter (VT-x => 64-bit) is most often true but not always. Thank you Intel, my Core Duo can VT-x but not 64-bit! Kind regards, Frank -- Dr.-Ing. Frank Mehnert Sun Microsystems http://www.sun.com/
