Hi Folks: I am oot able to add HP Intel 4Port PCIe to a linux hvm domain. HW is a HP DC7900. ErrorMessage: VmError: pci: to avoid potential security issue, 0000:22:00.0 is not allowed to be assigned to guest since it is behind PCIe switch that does not support or enable ACS. I also added in /etc/xen/xend-config.sxp: pci-passthrough-strict-check no pci-dev-assign-strict-check no but no success. Same HW Configuration works without any changes under xen 3.2.1 ! Thanks for your help !

yes... I think think we need more debugging. But how ? -- View this message in context: http://xen.1045712.n5.nabble.com/PCIe-switch-that-does-not-support-or-enable-ACS-tp3320277p3320562.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
