v1.0.6-5-g33e3002
This bug verified pass in libvirt-1.1.0-1.el7, steps as bug description. --config working fine:
# virsh list --all
Id Name State
----------------------------------------------------
9 rhel7 running
2.Prepare a xml.
# cat usb_bus.xml
<hostdev mode='subsystem' type='usb' managed='yes'>
<source>
<address bus='1' device='9'/>
</source>
</hostdev>
3. In guest, to check the usb device.
# lsusb
Bus 001 Device 002: ID 08e6:4433 Gemplus GemPC433-Swap
Bus 001 Device 003: ID 0409:55aa NEC Corp. Hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
4. Attach usb device to the guest using attach-device with --config.
# virsh attach-device rhel7 usb_bus.xml --config
Device attached successfully
5. In guest, to check the usb device again.
# lsusb
Bus 001 Device 002: ID 08e6:4433 Gemplus GemPC433-Swap
Bus 001 Device 003: ID 0409:55aa NEC Corp. Hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
There is no pluged usb to guest.
6. Destroy and restart the guest, and to check the usb device.
# virsh destroy rhel7
Domain rhel7 destroyed
# virsh start rhel7
Domain rhel7 started
# lsusb
Bus 001 Device 002: ID 08e6:4433 Gemplus GemPC433-Swap
Bus 001 Device 003: ID 0409:55aa NEC Corp. Hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 148f:3370 Ralink Technology, Corp. RT3370 Wireless Adapter
After restart guest, there it is.
Working well.
Setting VERIFIED.
