setting motherboard serial number?

setting motherboard serial number?

[Oliver Rath]

Hi list,

i have a little problem: a program of us is looking for the serial
number of the motherboard via

dmidecode -s baseboard-serial-number

which returns normally (i.e. Athlon Board) a 16-digits-number.

But doing this in a virtualized (i.e. Ubuntu-oneric-11.10) box, the
command returns the empty string.

Is there any possibility to set this number when defining the virtual
machine?

Tfh!

Regards,

Oliver

I believe you only can specify type 0 and type 1 entries as text fields
at the moment, while you are interested in type 2 (baseboard).  But what
you can do is load it as a binary blob.  If you don't care about the
values, you can probably just use a dump from a real machine.

Something like 

  dmidecode -t2 --dump-bin my-type2.bin

and then

  kvm -smbios file=my-type2.bin ...

might do the trick.  Totally untested of course :-)
