I would like to gain some idea of the XCP impact of these two CPU versions: Intel Core i7-2600, 3.4 GHz Core i7-2600K, 3.5 GHz Both have VT-x Differences 2600K does not include: Embedded Opions Available vPro Technology Virtualization Technology for Directed I/O Trusted Execution Technology Is the difference critical? Thanks, ray

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. -- Fajar

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? Thanks, ray

In virtualization, VM''s GUI is often accessed remotely (e.g. rdesktop/vnc). In that case, you don''t need GPU passthru. Actually, you don''t even need a GPU at all (IIRC some old sun x86 server don''t even have a GPU). Usually you''ll need GPU pasthru ONLY if you xen on your desktop/notebook, and directly use the monitor/keyboard/mouse to do something 3d-related (e.g play game) on the domU directly. For most other cases, remote console will be enough.> > What kind of remote console might a mother board support?Not sure about desktop. For servers, for example HP as ILO, DELL has DRAC, etc. There''s also KVM over IP. -- Fajar
