hi all

I have Dell T410 server with 2x X5650
I have installed ESXi 5.5 on it, and then I installed windows 7

I want to install GNS3 ER on it, after installing virtualbox, then I imported the GNS3 IOU VM, but it shows me this error when I run it

You're attempting nested virtualization which VirtualBox doesn't support. Refer to https://forums.virtualbox.org/viewtopic.php?f=1&t=55519 for more information.

I suggest you try to disable VT-x in VirtualBox.
Settings->system->acceleration->VT-x
