What is the difference between VT-d and VT-x in terms of virtualization support?
I want to buy a Dell server and run ESXi but I want to make sure I get the right chip. Under the system requirements for vMA (vSphere Management Assistant), it says that VT-d technology is required on the chip.
On the chip I am looking at (Xeon E5630), the Intel site says it has VT-x technology.
In a Wikipedia article on the subject it seems that VT-d is newer than VT-x.
What I care about is that the Xeon E5630, with VT-x support, is everything I need for full 64-bit ESXi and vMA.
If anybody has any opinion on this I'd appreciate it.
Thanks.

You are but are not :)
All VMs use the host resources as its own, but is done through the VMM layer (hypervisor), not 'directly'. The real need for "direct use" users have had is for USB connection, since USB isn't supported natively in ESX/i yet.

Thanks, coolsport. And that support for USB connection (which I don't need on my VM's) is separate from the suggestion you gave on another thread to run VMWare ESXi OS on a Flash Drive and use all the HD's as Data Store, right?
I don't need "direct use" to do that, do I? (I definitely want to try that trick!)

Yes..it's separate :)
USB is seen by the server hardware (installing ESXi on USB), but ESX/i cannot see USB-attached storage.

When I accept the standard networking, for example, when setting up a new windows vm on my ESXi server, am I using the Ethernet card "directly"? If not, then I don't need VT-d.
(Thanks for the links. Very interesting reading.)
