Subject: Add support for libvirt domain <sysinfo> XML config

Libvirt domains can have system metadata defined in a <sysinfo>
XML element. For the x86 platform with KVM guests, this can then
be used to populate the SMBIOS data tables

            <sysinfo>
              <bios>
                <entry name="vendor">Acme</entry>
              </bios>
              <system>
                <entry name="manufacturer">Acme</entry>
                <entry name="product">Wile Coyote</entry>
                <entry name="uuid">c7a5fdbd-edaf-9455-926a-d65c16db1809</entry>
              </system>
            </sysinfo>
