[libvirt-users] usb post passthough stopped workng after kernel upgrade
Greetings, I have a vm on debian 9.5 to which I pass an specific usb from the host. here is the relevant part in the vm's xml file: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x148f'/> <product id='0x5572'/> </source> <address type='usb' bus='0' port='1'/> </hostdev> the address line was added automatically by libvirt. everything was working well with kernel 4.15.11-1~bpo9+1 until I needed to upgrade the kernel to latest possible version due to usb issues I've upgraded to 4.18.6-1~bpo9+1. after the upgrade, my vm doesn't starts anymore, I see this msg: error: Failed to start domain router error: internal error: qemu unexpectedly closed the monitor: 2018-11-02T13:43:32.174730Z qemu-system-x86_64: -device usb-host,hostbus=1,hostaddr=4,id=hostdev4,bus=usb.0,port=1: failed to find host usb device 1:4 how can a kernel upgrade cause this? is there a fix for this issue? Thanks, Dagg.
anyone has any idea regarding this issue?

Solved! apparmor was to blame, I've disabled it on kernel params and all works again.
