Looks like the xenapi driver is unable to get the product version from the host and when that happens there is no warning logged or anything, None is just returned:
https://github.com/openstack/nova/blob/master/nova/virt/xenapi/driver.py#L688
That sets the var that is passed to utils.convert_version_to_int.
I'm not sure why the driver can't get the product version from the host since I don't know much about the xenapi driver.
