Re: [Xen-users] Passthrough USB Controllers



Hi Tobias,

Yeah I spent last night compiling and testing, 3.5 and 3.5.2 both have the same bug with USB Controllers, odd since video works fine.

I did not encounter a crash when shutting down the virtual machine, I had two instances of Win7, one with PVHVM drivers, one without, both acted the same with the passed devices.

However, I did not try running shutdown or destroy from xl.

Thanks for verifying it wasn't just me.

Hi Casey,

encountered the same problem with 3.5 as Dom0 kernel, see here
http://lists.xen.org/archives/html/xen-devel/2012-08/msg00562.html

Konrad could - partially - reproduce this and i guess it will be
fixed in 3.6 (guess!)

do you also encounter the dom0 crash when shutting down dom0?

Good Evening,

I am testing our Xen 4.2 RC3 on Wheezy with the latest Kernel 3.5.2, and
encountered a bug.

I am certain it is stemming from the latest kernel, since the bug is not
present when using kernels 3.3.8 and 3.4.9.


I am running a Windows 7 HVM and passing USB 2.0 and USB 3.0 controllers,
as well as my graphics card.

The graphics card works, and to my surprise the USB controllers are the
problem.

Windows just gives me a Code 10 for all three, I tried each PCI device solo
with no changes, so it wasn't a conflict, and the qemu log appears no
different than with the other kernels.

Any ideas what logs I should check?  Also, is anyone aware of any changes
to the 3.5.2 kernel that could cause problems with USB controllers?

Thanks,

~Casey
