Does intel Xeon e5620 have EPT support

http://en.wikipedia.org/wiki/Trusted_Execution_Technology - Intel TXT includes Intel VT-d

This technology is coupled with VT-d (Intel Virtualization Technology for Directed I/O) which, among other things, protects certain areas related to TXT from DMA access.

You can read about VT-D here.

Basically it's

1. I/O device assignment. This feature allows an administrator to assign I/O devices to VMs in any desired configuration.

2. DMA remapping. Supports address translations for device DMA data transfers.

3. Interrupt remapping. Provides VM routing and isolation of device interrupts.

4. Reliability features. Reports and records system software DMA and interrupt errors that may otherwise corrupt memory of impact VM isolation.

The entire point of which is to provide hardware support for the functions that hypervisors currently do in software. This also requires chipset/bios support so it is not drop in replaceable
