Hi guys. I had purchase a computer and looks like the MoBo and CHIP wont support IOMMU: AMD Athlon X4 640 Biostar A780L3L Biostart technical support confirm that this MoBo doesn''t support IOMMU and don''t have plans for it. Now, amd still not answer to. Well, I want to pass USB ports to my win7 HVM, Intel say is more clear about their settings and features, I found a link where it point me what MoBo support both VT/VT-d. Q67 DQ67EP; DQ67OW; DQ67SW Q57 DQ57TM; DQ57TML Q45 DQ45CB; DQ45EK Q35 DQ35JO; DQ35MP I would like to know if some here can confirm what MoBo/CPU pair have u been able to run Xen PCI Passthrough. I will appreciated any input,thanks. OS:Centos 5.7 x64 HVM:Win7 x32. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
