You are using VirtualBox and have configured the virtual machine. But, whenever you try to start the virtual machine, you are dumping with below error,
Failed to open a session for the virtual machine CTC.
VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED).
Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}
Solution
1. Go to Setting. Choose System and under the Acceleration tab, make sure the Enable VT-x/AMD-V is checked.
2. Go to your computer BIOS (different computer manufacturers will have different way – google!) and enable the virtualization technology.
3. Restart your computer and start the virtual machine.
4. If above steps are not working, reduce the processor and start the virtual machine.
