Multiple Virtual Machines on windows 7

A new Laptop with the good resources with Windows 7 Ultimate which has got the Windows XP mode is really marvelous as most of the Oracle programs needs to be installed on x86 platform or in windows XP.


After a brief search for the free and reliable virtual machine for Windows 7 found Oracle VM Box. After Installation and when we tried to start the VMBOX, it keeps on getting the error as "VirtualBox can't operate in VMX root mode.

VBox status code: -4011 (VERR_VMX_IN_VMX_ROOT_MODE)."

After a few minutes of research and Google found that, we can;t open the 2 virtual machines on same system :(


Reason: VT-x and AMD-V compatible issues

So, need to use any of the one VM System at a time.

Solution: Shutdown the Microsoft Virtual Machine and it's Services and restart your computer. Later start the Oracle Virtual Box.

I see the same issue, but only if I start XP Mode first. If Vbox is running when I start XP Mode, it seems to work alright. Still a pain, but workable.
