Dear Gurus,
I am trying to install 64-bit guest OS (OEL) on my laptop which is running on 64-bit Windows 7. However while doing so I am getting "your cpu doesn't support long mode use a 32 bit distribution". Earlier I was able to install on a different laptop but now on any laptop the same problem is coming. I read many post from here but could not get any solution. Kindly advice

Make sure Hyper-V or XP-mode is not enabled on the host.

And that hardware virtualization is available and enabled in your bios, and that your CPU also supports Hardware virtualization.
