I attached x64 virtual machine, but when I run it, I got error that VT-x is not available. Hardware virtualization enabled for my machine, I know that there is settings for virtual box for enabling VT-x, but I can't found it in 4.02 version.
How to enable this setting for virtual box?

UPD
When I try to create a new virtual machine, x64 version is missing in list of available versions in some reasons.

It is under Settings->System->Acceleration Tab. Don't forget to activate it in your BIOS, too.

I haven't this tab (virtual box 4.02v) – Kai Jan 10 at 14:26
@Kai maybe update to the recent version, I am using v4.18 under linux. – bamboon Jan 10 at 14:28
@Kai I just googled a bit and that tab should be there. Did you check if vt-x is enabled in your BIOS? – bamboon Jan 10 at 14:37
I enabled hardware virtualization in bios, but I'm not sure if vt-x and hardware virtualization in bios is the same? – Kai Jan 10 at 14:52
@Kai It should actually be the same. However you should see the tab anyway. – bamboon Jan 10 at 15:01
