According to the log file, VT-x is not enabled in the host's BIOS.
Common: MSR 0x3a = 0x1 --> currently "0001" , should be "x1x1" (e.g. 0x5)
Please follow the steps mentioned in the error message and - once in the BIOS - consider to also enable "Execute Disable". This is required if you want to install e.g. Windows 8/2012.
