VirtualBox 3.1.6_OSE r59338 linux.amd64
I wanna to install a virtual system with x86-64 in Virtual Box,But it seemed that it is impossible to do this.
The virtual machine tips me it only detected an i686 CPU.
Is there any link between the architecture of host and that of the client virtual OS?
INFO: Your CPU supports KVM extensions INFO: /dev/kvm does not exist HINT: sudo modprobe kvm_amd KVM acceleration can NOT be used
sudo modprobe kvm_amdresult
FATAL: Error inserting kvm_amd (/lib/modules/2.6.32-24-server/kernel/arch/x86/kvm/kvm-amd.ko): Operation not supported
INFO: Your CPU supports KVM extensions INFO: KVM is disabled by your BIOS HINT: Enter your BIOS setup and enable Virtualization Technology (VT), and then hard poweroff/poweron your system KVM acceleration can NOT be used
But another problem happened,the VirtualBox displayed an error windows.:
VT-x/AMD-V hardware-acceleration has been enabled,but it is in the ineffective status. So the VirtualBox won't detect the CPU of 64bit,and fail to start.Please confirm the support has been enabled.
How to check the CPU whether support the
VT-x/AMD-Vtechnology?And start it in BIOS?But another Virtual OS (32bit)also enable this technology,and works well.
