Re: [libvirt] [PATCH] 0/4 Add SMBIOS settings to domain definition

 The SMBIOS data are a standardized set of data structures available in the BIOS area of PCs. Those blocks of data describe things like BIOS version informations, machine vendor, model and identifiers, as well as various parts of the machine capability. On a linux machine running dmidecode allows to dump those informations.  Spec available at the DMTF: http://dmtf.org/standards/smbios  From a virtualization POV, it's mostly the first block describing the BIOS named "type 0" and the second block describing the machine named "type 1" which are of interest. Those data are usually accessed either from the OS or from management application, and being able to override the default setings may be needed for such management.  The suggested XML description follows the logical structure of the data, one top smbios description, with one or more blocks, each containing the entries, the example below gives an idea:  <smbios>    <table type="0">      <entry name="Vendor">QEmu/KVM</entry>      <entry name="Version">0.13</entry>    </table>    <table type="1">      <entry name="Manufacturer">Fedora</entry>      <entry name="Product">Virt-Manager</entry>      <entry name="Version">0.8.2-3.fc14</entry>      <entry name="UUID">c7a5fdbdedaf9455926ad65c16db1809</entry>    </table>  </smbios>  The patch serie includes:   - the change to the doamin schemas   - the code to parse this in config structure   - the QEmu driver part   - a test example Currently missing is the conf code to save the data back, and documentation for the domain extension. I think it's possible set some of those settings in Xen too, but I don't know if I will take the time of a driver for it. For ESX it seems there is an option to inherit some of the SMBIOS data from the host on the guest but I'm not sure some of the fields can be manipulated directly. I don't know what  VirtualBox can set there either, Daniel
