[Xen-devel] [Bug] PVUSB, Ubuntu 12.04, Xen 4.1.2

[Erwan PILLET <erwan.pillet@xxxxxxxxxxxxxxxxxxx>]

Hi everyone,

I installed xen from packages on Ubuntu 12.04, getting the version 4.1.2 .

I wanted to use pvusb which I understand was functional on this version to pass an USB hard drive to my DomU, but I only manage to get this error trying to attach the device to a domain.

It may also be worth mentionning that "xm usb-hc-destroy mydomu 0" doesn't have any effect, so it doesn't give back any error (I get one if I try on an unregistered devId) but don't remove the host controller.

So should pvusb be fonctionnal on this version of xen/xm ? If yes, any help would be highly appreciated.

Thanks,

Erwan
