Linux 64 Host but impossible to install Guest 64

[cobalt78]

Hi all

I can't install linux guest ubuntu/fedora 64 on my PC with host Ubuntu Hardy 64bit

The Virtualisation on bios is enabled, the vmx is enable on my pc in /proc/cpuinfo

I check VT-X/AMD-V and PAE/NX

Why i can't install 64bit on 64bit

Thanks
