[Qemu-devel] QEMU 2.1.2 w/ libvirt - USB host assignment doesn't work

[Erik Rull]

Hi all,

I started with QEMU emulator version 2.1.2 backport on ubuntu 14.04 (I also tried the QEMU 2.0.0 that is provided natively with this version) and I can't get the USB device redirection working properly.

No idea what actually goes wrong. I have the 32 bit version running properly without any problems on other systems.

Below the usbhost and usb output from monitor + commandline.

I would like to have the device from hostbus 1 / hostport 2 routed to my guest.

Any help appreciated.

Thanks.

Best regards,

Erik
