Hi,

I have a Toshiba 4th gen core i5 laptop with 4200u processor. It does not support vt-d. Will there be any limitations on virtualization.

Can you please reply the virtualization features not possible without vt-d?

Regards,
Sriram.K

Yes.  It will be slower.

You can still virtualize.  But you lose access to hardware on the computer system.

Lack of vt-d is not a major issue unless you are trying to run a virtual machine that needs you to "pass through" hardware I/O.    For example, if you were running a NAS in a VM, you'd probably want to pass through the actual disk controller that the drives were attached to instead of just using the disks through the hypervisor.

But for the vast majority of uses, there is NO effective loss of performance -- especially on a laptop, where it's VERY unlikely there is any special hardware you need to pass through to the VM.
