Thank you experts !

VirtualBox – Error

Filed to open a session for the virtual machine Windows-XP-SP3.

VirtualBox can’t operate in VMX root mode. Please disable the KVM Kernel extension, recompile your kernel and reboot

(VERR_VMX_IN_VMX_ROOT_MODE).

Using KVM and Virtual Box side by side

Hello,

If you have got any double virtualization software running both at the same time, this problem will occur. Both software will try to access the “VT-x” and “AMD-V” which should not be happening. In order to fix this issue, you must disable the other one which is conflicting with VirtualBox.

Also, disable the KVM module from your kernel.

1. Press “Ctrl + Alt + T” to open Terminal.

2. Type and enter the following command:
sudo modprobe –r kvm_intel

3. Enter the password for your root account.

Also, you might have got “qemu-kvm” installed. Recommend to remove it too if no improvement seen from the above steps.

Now, run VirtualBox. Also, try the latest VirtualBox. Download VirtualBox.

This should solve the issue.
