Windows Update inside KVM virtual machine crashes iwlwifi

February 8, 2013

And I was wondering why running Windows Update inside a KVM virtual machine failed with some mysterious error code:

This is my KVM host, of course, running openSUSE 12.2. Seems Intel hasn’t progressed much with the instability issues in the Centrino WLAN chipsets, this is a Intel Wifi Link 5300 and I had similar issues ever since the 2200BG chipset. And www.intellinuxwireless.org apparantly does not exist any more. Various tickets have been filed for Ubuntu, Fedora and others.

The funny thing is: this only happens when I start Windows Update inside the VM, which is NATed to the host. I can download Gigabytes in both the host and the guest system, and the driver runs without the slightest problem.

Workaround for SUSE:


cat "options iwlwifi 11n_disable=1" >>/etc/modprobe.d/99-local.conf
