The kernel doesn''t support reset from sysfs for PCI device...
Hi, i have an old proliant dl380 server, running hardened gentoo as Dom0 on Xen 4.2, with several DomUs, also running hardened gentoo. I have PCI passthrough working for a DomU (3 network cards, 2 wired, 1 wireless), but when i try to pass it my usb root hub, i get the following error, during xl create (or when i use xl pci-attach): libxl: error: libxl_pci.c:1001:libxl__device_pci_reset: The kernel doesn''t support reset from sysfs for PCI device 0000:00:0f.2 After that, the system (both Dom0 and the DomUs) are terribly slow, sometimes completely inaccessible (took me several minutes to get the dmesg output (see attached for full output) and i get the following: Dom0 dmesg [ 407.581924] xen-pciback[0000:00:0f.2] IRQ line is not shared with other domains. Turning ISR off [ 409.004566] irq 11: nobody cared (try booting with the "irqpoll" option) [...] [ 409.004761] Disabling IRQ #11 xl dmesg (XEN) Cannot bind IRQ11 to dom1. Will not share with others. After that, all i can do is to reset the box. For more information about my config see attachment: kernel config (both Dom0 and DomU): .config DomU config: DomU Dom0 grub config: grub0.conf DomU grub config: grubU.conf lspci -vvv: lspci Dom0 dmesg after the problem: dmesg i''ve tried to reorganize the pci cards, but that didn''t help what can i do to solve this problem? regards, Gabor Hudiczius _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
