[libvirt] How to define QEMU/SMBIOS Attributes in virsh
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: [Qemu-devel] [PATCH 2/2] smbios: Allow device ID instead of PCI address http://lists.gnu.org/archive/html/qemu-devel/2013-11/msg02350.html @@ -1336,9 +1338,10 @@ Specify SMBIOS type 0 fields Specify SMBIOS type 1 fields @item -smbios type=41,address@hidden,address@hidden,address@hidden,status=on|off][,address@hidden|n}] address@hidden -smbios type=41,address@hidden,address@hidden,address@hidden,status=on|off][,address@hidden|n}] Add SMBIOS type 41 fields (Onboard Devices Extended Information).

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 https://www.berrange.com/posts/2011/12/19/using-command-line-arg-monitor-com...

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 Am 01.07.2015 um 19:49 schrieb Daniel P. Berrange:
