Hi all, After having great success exporting my video card to a paravirt domu, I decided to try the USB controllers. It appears that all should be working, but when I connect a USB device, I get a hung box :-( Here is my info: DOM0 ---------------- Xen 3.1.0, Kubuntu Gutsy AMD64 root@hydra:~# lspci|egrep "USB|VGA" 00:1d.0 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #3 (rev 02) 00:1d.3 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #4 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02) 05:00.0 VGA compatible controller: nVidia Corporation NV38GL [Quadro FX 1300] (rev a2) root@hydra:~# grep pciback /etc/grub.conf module /vmlinuz-2.6.22-14-xen root=/dev/mapper/hydra-root ro xencons=xvc console=xvc0 console=tty1 swiotlb=force pciback.hide=(05:00.0) (00:1d.0)(00:1d.1)(00:1d.2)(00:1d.3)(00:1d.7) root@hydra:~# cat /sys/bus/pci/drivers/pciback/slots 0000:05:00.0 0000:00:1d.0 0000:00:1d.1 0000:00:1d.2 0000:00:1d.3 0000:00:1d.7 root@hydra:~# cat /etc/xen/aphrodite.cfg # # Configuration file for the Xen instance aphrodite, created # by xen-tools 3.5 on Mon Nov 26 14:24:09 2007. # # # Kernel + memory size # kernel = '/boot/vmlinuz-2.6.22-14-xen' ramdisk = '/boot/initrd.img-2.6.22-14-xen' memory = '2048' vcpus = '4' pci = ['05:00.0', '00:1d.0', '00:1d.1', '00:1d.2', '00:1d.3', '00:1d.7'] #extra = clock=jiffies # # Disk device(s). # root = '/dev/sda1 ro' disk = [ 'phy:hydra/aphrodite-disk,sda1,w', 'phy:hydra/aphrodite-swap,sda2,w' ] # # Hostname # name = 'aphrodite' # # Networking # vif = [ 'ip=10.0.0.9' ] # # Behaviour # on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' -------------------------------------------End of Dom0----------------------- So, everything looks OK on the Dom0 side DomU -------------- Also Kubuntu Gutsy $ lspci|egrep "USB|VGA" 00:00.0 VGA compatible controller: nVidia Corporation NV38GL [Quadro FX 1300] (rev a2) 00:01.0 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #1 (rev 02) 00:01.1 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #2 (rev 02) 00:01.2 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #3 (rev 02) 00:01.3 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #4 (rev 02) 00:01.7 USB Controller: Intel Corporation 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02) It looks like USB should work. When I run "lsusb" the command never returns even when run by root. It is a juggernaut; even "kill -9" won't stop it! When I plug a USB device in, I get hangs all over the place, until I unplug it.

This may be harmless, but if you have problems with your device: [ 51.779455] 1) see permissive attribute in sysfs [ 51.779458] 2) report problems to the xen-devel mailing list along with details of your device obtained from lspci. I tried setting the permissive attributes, like this: root@hydra:~# cat /etc/xen/xend-pci-permissive.sxp (unconstrained_dev_ids #('0123:4567:89AB:CDEF') ('0000:00:1d.0' '0000:00:1d.1' '0000:00:1d.2' '0000:00:1d.3' '0000:00:1d.7') ) I'm stumped. Any help would be greatly appreciated! Paul _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
