Thanks for reporting this bug. Can you tell use exactly how you told virt-manager about the printer? For other types of usb devices (like an ereader) this has definately created the needed rules for me.
Adding a blanket '/run/udev/** rw' rule would not be safe, but we should be able to find a way to add the needed rules through virt-aa-helper. status: incomplete priority: medium ** Changed in: libvirt (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1515791 Title: apparmor for qemu is too restrictive for USB passthrough To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1515791/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
