Hello,

here is a problem with KVM passthrough of TechnoTrend S2-6400.

Bug report is done.

The last answer of the debian maintainer:

--> Please check with lspci -vv whenever your device is MSI-capable,

--> and if yes, try to add prefer_msi=on to the pci-assign device

--> argument -- like, from your original report,

-->

--> -device pci-assign,host=08:00.0,id=hostdev0,configfd=23,bus=pci.0,addr=0xa,prefer_msi=on

-->

--> I don't know how to add this to libvirt however, maybe they have

--> some knobs for that nowadays.

and now my question:

How do I add the parameter "prefer_msi=on" to the xml file?

Thank and greets klak2
