You need XCP for that and the= n it is still very experimental with NO documentation except what is in the= code.

Subject: [Xen-users] pci passthr= ough and Xenserver

Hi,

We are running Citrix Xenserver 5.5(do= m0) and PV guests(domU). Since VT-d support is not required for PV guests h= as anyone tried pci passthrough with Citrix Xenserver? If yes what config f= ile 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.<= br>
Thanks
