changing vm's product serial

This Serial Number is located into=20 /sys/devices/virtual/dmi/id/product_serial, and we'd really want each vm=20 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=20 the product_serial file. Is there a simple way to do such a thing?

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() --->8--- -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.

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 Le 09/03/2016 12:35, Juan Hernández a écrit :
