Hi everyone   I start a new conversation because I read many of your messages while trying to solve my problem but I couldn't solve it... Can you please help me?   I downloaded VirtualBox 5.2 and Cloudera-quickstart-vm-5.4.2-0. My computer is 7 years old and has an Intel Core i5-3210 (2,5GHz), RAM 8Go and is coded in 64bits. When I try to start my Cloudera VM, I always get an error message saying:   "VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED) Error Code : E_FAIL (0x80004005) Component : ConsoleWrap Interface : IConsole {872da645-4a9b-1727-bee2-5585105b9eed}"   Do you have any suggestion on this case?   Your help would be much appreciated!!    Thanks a lot,   Jean Baptiste ...
