Kernel requires an X86-64 CPU...

[poiu]

I tried to update VirtualBox at the start of November and haven't had it working since. None of my VMs would start. De-installation failed. Couldn't reinstall. Major faff. Have now managed to get VirtualBox installed and have given up on my old VMs.

However, now, on a completely new installation, I'm getting the "This Kernel requires an X86-64 CPU, but only detected an i686 CPU." error.

I'm running OSX 10.6.8 with an Intel Core 2 Duo. System Profiler reports "4-bit Kernel and Extensions: Yes" (I enabled it as a result of searching these forums, I've never had it enabled before and have never had problems).

Does anyone have any idea what's causing it?

This Kernel requires an X86-64 CPU, but only detected an i686 CPU.

In the VM settings, General, Basic, Version, change the guest type to the 64-bit variant.

Arrrrggghh. How have I never seen that before? What a waste of a day.

Thanks.

It's because its a new option after 4.3.x.

Actually it has always been this way. Its just that some users register it as normal (32-bit) and edited the settings to allow for (64-bit) and that does not work since 4.3.*

Thank's a lot, it did the trick!
