Public bug reported:

Version: nova-2013.1.4 (Grizzly)
Driver: libvirt
Hypervisor: KVM
Host OS: Ubuntu 12.04 LTS
Description:
To get instance UUID, I tried to use "wmic CSPRODUCT" command on a Windows guest, but the result was different from the instance uuid.

See below:
https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L3099

Libvirt driver used get_host_uuid() in nova.virt.libvirt.driver and it
returns the host uuid, so the VMs on a host get same computer system
product id from SMBIOS. I think each  VM should have an unique value as
computer system product id.
