Hi,
how can I define passthrough of all USB-slots to a guest with libvirt?
With qemu it's very easy:
# kvm -usb -usbdevice host:0.* -usbdevice host:1.* -usbdevice host:2.* -usbdevice host:3.* ...
This configuration of the VM gets *all* 4 USB-Slots. Every time somewhat USB-device
is plugged in the VM gets it.
virt-install manpage offers:
--host-device 001.003
USB by bus, device (via lsusb).
I installed a VM with option --host-device 001.001 according to output of lsusb.
The XML-file generated:
<hostdev mode='subsystem' type='usb' managed='yes'>
<source>
<vendor id='0x1d6b'/>
<product id='0x0002'/>
</source>
</hostdev>
But no USB device is passed through automatically. I always need
virsh attach-device virtualM myusb.xml
with exact vendor and product ID. I want to plug in somewhat USB-Stick or other USB stuff
without exploring vendor and product id before.
Who can help?
