I have xeon quad core server I wonder if is possible to assign pci usb device to pv if the server does not suport iommu vd-t I had blacklisted usb modules and hid devices and devices are listed as assignable but when I add them to pv I get this error libxl: error: libxl: error: libxl_pci.c:989:libxl__device_pci_reset: The kernel doesn''t support reset from sysfs for PCI device 0000:00:1d.0 libxl: error: libxl_pci.c:989:libxl__device_pci_reset: The kernel doesn''t support reset from sysfs for PCI device 0000:00:1d.1 Daemon running with PID 897 _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

I get that on, for example, the VGA card passed through to the VM, but it still works inside the domU. It just means the device doesn''t support FLR. Gordan
Well the strange part is that when I assign devices in this case all usb ports lspci lsusb does not show anything. Is even posible to assign device if system does not support iommu there is vd-t ?
