This behavior is consistent with Xen > 4.0.1, 4.0.2.rc1-pre and 4.1. I just checked on my SuperMicro X8DTN, this combination - For Dom0, git commit fe999249 (2.6.32.18) - For DomU, devel/xen-pcifront-0.6 or devel/xen-pcifront-0.7 - For Hypervisor I used cs 21976, but found that the latest (22155) works too with which where I passed in PCI devices with legacy IRQ, MSI, and MSI-X. I tried a combination of doing this with IOMMU (VT-d) and without - both cases these devices: 00:1d.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02) 03:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) (rev 06) 0a:00.1 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) worked just fine (either defining pci=["..."] or just using pci-attach). But if I use the latest xen/next or xen/stable-2.6.32.x it does not look that happy :-( _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
