I did go through  vmops.ml and I really didn't get much information on what config file it is reading or what changes are needed. I looked at http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_module from the link given by Dullor, not sure whether those changes suffice XCP for pci passthrough hence thought of checking. Any inputs?

No PCI passthrough for XenServer AFAIK.
You need XCP for that and then it is still very experimental with NO documentation except what is in the code.

Subject: [Xen-users] pci passthrough and Xenserver


We are running Citrix Xenserver 5.5(dom0) and PV guests(domU). Since VT-d support is not required for PV guests has anyone tried pci passthrough with Citrix Xenserver? If yes what config file changes are required in domU and dom0? I looked at Citrix forums and xen.org/xen-users archives, not getting useful information from it. Inputs much appreciated.
