thank you, it's ok for the python script!
another simple way I found is with ovirt-shell:
ovirt-shell -E "update vm name --serial_number-value $(uuidgen)"
anyway we need not to simply reboot, but stop and start the vm so as to
this change take effect

Hi all,
We've been using templates for months before we realized that "ocs
report" used Serial Number given into "demidecode -t system" to identify
a VM as unique.
This Serial Number is located into
/sys/devices/virtual/dmi/id/product_serial, and we'd really want each
vm to have its own Serial Number instead of the template's one.
We tried to generate a new id with uuidgen, but it can't be written into
the product_serial file.
Is there a simple way to do such a thing?
Thank you.
You can change the serial number of the VM via the GUI:
Vms -> Edit -> System -> Provide custom serial number
There you can specify that the VM should have as serial number the id of
the host, the id of the VM, or a custom serial number.
You can do the same with the API. For example, to set a custom serial
number for a specific VM using the Python SDK you can do something like
this:
---8<---
#!/usr/bin/python
from ovirtsdk.api import API
from ovirtsdk.xml import params
# Connect to the server:
api = API(
url="https://engine.example.com/ovirt-engine/api";,
username="admin@internal",
password="...",
ca_file="/etc/pki/ovirt-engine/ca.pem",
debug=False,
)
# Find the VM:
vm = api.vms.get(name="myvm")
# Set a custom serial number:
vm.set_serial_number(
params.SerialNumber(
policy="custom",
value="yourserial",
)
)
vm.update()
# Disconnect:
api.disconnect()
