It depends.

What are your use cases? If it's just for a headless, common virtual
server setup, with remote access using rdp/vnc/whatever, then it
shouldn't matter.

Vt-d is important if you want to use pci or GPU passthru, but GPU
passthru is kinda hit-and-miss, with some hardware combination better
than others. Search the list archive for GPU passthru if you're
interested in this. If you're an average end-user, chances are you
won't be needing this.

vpro might be useful for remotely controlling the physical server, but
an IP-based KVM or server-grade motherboard with remote console
facilities can provide the same functionality.

As for others, just do some research. I'm not sure those capabilities
are even used by xenserver right now.




Thank you very much.  You have given me insight and added to my search
vocabulary - things I really need.

I will require GUIs for most of my VMs.  I have been searching and
participating in threads relative to PCI pass throuh and found some
information - there are a lot of problems but only a few individuals
bring forth their findings - very valuable.  

What kind of remote console might a mother board support?
