Hi Daniel,
thanks a lot for this information.
I think thepassthrough is usable as a work around meanwhile.
How do I write a bug report (via the HP of libvirt)?
Best regards
Holger

Hello,
I have a "request for Help" please.
Myself:
I'm a native german language speaker and
I' work with qemu/virsh since 6 months now.
At the moment I try to define/configure qemu/smbios
attributes in a virsh xml-file.
My current problem:
I need to configure two on-board lan elements.
Thanks to Gerd Hoffmann (Qemu group). He gave me the hint for
smbios/acpi configuration. For this configuration I need a
type 41 record. I found on http://libvirt.org some descriptions
for smbios but only for type 0 and 1.
In qemu the solution is available:

Add SMBIOS type 41 fields (Onboard Devices Extended Information). Could be
specified multiple times for different devices. Mandatory options are
address@hidden in form "[[<domain>:]<bus>:]<slot>.<func>" and
address@hidden in form "[[<domain>:]<bus>:]<slot>.<func>" or @option{id},
and
@option{instance} number. @option{instance} shoud be in range [1, 255] and
should be unique within specified @option{device-type}.
@option{designation} is
an optional string that somehow designates device. @option{status} is a
device

So my question: How can I configure such record in a virsh xml-file please.
There's no official support for SMBIOS type 41 fields in libvirt. Please do
file a bug report requesting this feature against libvirt. Meanwhile your
only option is to use custom command line passthrough in libvirt
