Looks like I found it. The VM in my case is trying to access /sys/devices/pci0000:00/0000:00:1e.0/0000:01:04.4/usb6/devnum
but the abstractions/libvirt-qemu profile only allows /sys/bus/usb/devices/ r, /sys/devices/*/*/usb[0-9]*/** r, when it should (also) allow /sys/devices/*/*/*/usb[0-9]*/** r, With this line added the guest boots fine and immediately gets access to the USB device. I have attached a patch for this one-line fix, hope it helps. ** Patch added: "One-line fix for hostdev access to USB devices" http://launchpadlibrarian.net/47796844/libvirt-qemu.patch -- apparmor driver blocks access to hostdev and pcidev devices https://bugs.launchpad.net/bugs/545795 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
