There is no XML tag for specifying hard disk serial number KVM supports this, but lack of support from libvirt. It's very useful for virtualizing software which binds activation keys to HDD serial number. We have one. Also (less important), there are no XML tags for specifying other hardware identifications: CPU serial number, CPU name, Motherboard name/serial and so on.
The seiral number is supported by the '<serial>VALUE</serial>' tag within the <disk>. For example: <disk type='block' device='disk'> <driver name='qemu' type='qcow2'/> <source dev='/dev/HostVG/QEMUGuest1'/> <target dev='hda' bus='ide'/> <shareable/> <serial>XYZXYZXYZYXXYZYZYXYZY</serial> <address type='drive' controller='0' bus='0' unit='0'/> </disk> CPU name/serial is governed by the choice of -cpu arg given to QEMU, whcih is exposed via the <cpu> element in libvirt XML http://berrange.com/posts/2010/02/15/guest-cpu-model-configuration-in-libvirt-with-qemukvm/ The other fields mentioned are fixed in the QEMU BIOS.
Huge thanks! Please update documentation so far http://www.libvirt.org/formatstorage.html If that resource is not source of documentation, where to look ?
http://www.libvirt.org/formatdomain.html No information here too
