RE: [Xen-devel] Problem: WIndows domu switches power off

["Kay, Allen M" <allen.m.kay@xxxxxxxxx>]

Dietmar,

 

This is a known issue with WLAN passthrough cause by ME (management engine) interaction.  The latest xen-unstable has quirk to workaround issue.

 

Can you give it a try and let me know if it fixes the problem for you?  By the way, which brand of Core i5 laptop do you have.  I would like to see if I have one locally.

 

Allen

Subject: [Xen-devel] Problem: WIndows domu switches power off

 

Hi list,

I have a special effect on a Laptop with:

cpu: Intel(R) Core(TM) i5 CPU M 540 @ 2.53GHz with integrated graphics

Chipsatz: Intel QM57

with SLES11 SP1 (xen-4.0 with some patches from Novell)

I passed through the sound and WLAN pci controller to the guest.

I start a Windows 7 guest and while installing the driver for the WLAN

controller within Windows the power of the notebook got switched off.

I couldnt see any message on the serial console.

I tried Windows on bare metall and all runs very well. Later on starting this

Windows guest again the power got switched of after login into Windows - maybe

the WLAN driver got started there.

For a test I prepared a OpenSuSE 11.3 as HVM guest and were able to configure

the WLAN device without any problems.

And here I need some assistance to prevent the power off and to add some tracer

in the hypervisor.

By the way I have no problems with the sound device.

If wanted I can add more informations.

Thanks.

Dietmar.
