Hello, I am currently trying to configure of forwarding devices from specific USB ports which is supported by QEMU. But I don't see any support from libvirt side. Due to libvirt security it occurs to be impossible to passthrough devices from specific bus+port combination. As workaround I may suggest only writing udev rules which use specific script which adds devices to running domains. Unfortunately situation becomes more complicated when I do need to passthrough these devices during system boot -- the special service is required which will handle all these devices after libvirt-guests are up. Does anybody knows how I can do this passthrough without udev workarounds? Thanks. -- Best regards, Alexander Betaev
