Hi,

if I try to start the vm by virt-manager I get this detailed error log:

Fehler beim Starten der Domain: internal error: early end of file from monitor: possible problem: qemu-system-x86_64: -device usb-host,hostbus=1,hostaddr=3,id=hostdev0: 'usb-host' is not a valid device model name

Hi,

 From qemu-1.7 release version, the old usb-host(host-linux.c) had been removed,
re-implemented by libusbx. So you should build qemu with --enable-libusb, then
you can use usb pass-through capacity.

BTW, Gerd, should we enable libusb by default now? Thanks.


Best regards,
-Gonglei

Subject: [Qemu-devel] [Bug 1320360] [NEW] usb passthrough not working
anymore

Public bug reported:

Hi,

I'm using qemu 2.0.0 with opensuse 13.1 x84_64 bit as host and window7
as guest. Til qemu version 1.6.2 USB passthrough works perfectly, but
starting with qemu 2.0.0 passthrough stop working. I can still add the
usb device but when I start the guest following message appears:

"unable to execute QEMU command 'device_add': 'usb-host' is not a valid
device model name"

Then the guest will not start.

I try it with different usb devices (iphone, stick, hdd), always the
same error.

Are there any news / hints about this ?

Regards

Martin
