Hi, A quick question - Is it possible to perform PCI passthrough without using HVM(VT-d or AMD''s I/O-virtualization hardware)? Thanks, Asim _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks! I got confused by the Xen download page(the new features). My DomU and Dom0 are all PV.
