Description Коренберг Марк 2010-05-18 11:53:15 UTC
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.

Comment 1 Daniel Berrangé 2010-05-18 13:29:13 UTC
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

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 ?

No information here too

Comment 4 Коренберг Марк 2010-05-24 12:41:29 UTC
I have Ubuntu 9.10.

after virsh edit and adding serial number, it disappear!!
starting from which version, <serial> tag is supported ?

Comment 5 Daniel Berrangé 2010-05-24 12:48:52 UTC
From libvirt-0.7.1
