We have example script here: https://github.com/oVirt/python-ovirt-engine-sdk4/blob/main/examples/remo... $ ./remove_checkpoint.py -h usage: remove_checkpoint.py [-h] -c CONFIG [--debug] [--logfile LOGFILE] vm_uuid checkpoint_uuid Remove VM checkpoint positional arguments: vm_uuid VM UUID for removing checkpoint. checkpoint_uuid The removed checkpoint UUID. options: -h, --help show this help message and exit -c CONFIG, --config CONFIG Use engine connection details from [CONFIG] section in ~/.config/ovirt.conf. --debug Log debug level messages to logfile. --logfile LOGFILE Log file name (default example.log). Regardless, if you really need to use vdsm client, here is how to use the client correctly. $ vdsm-client VM delete_checkpoints -h usage: vdsm-client VM delete_checkpoints [-h] [arg=value [arg=value ...]] positional arguments: arg=value vmID: A UUID of the VM checkpoint_ids: List of checkpoints ids to delete, ordered from oldest to newest. JSON representation: { "vmID": { "UUID": "UUID" }, "checkpoint_ids": [ "string", {} ] } optional arguments: -h, --help show this help message and exit The vdsm-client is a tool for developers and support, not for users, so we did not invest in creating an easy to use command line interface. Instead we made sure that this tool will need zero maintenance - we never have to change it when we add or change new APIs, because is simply get a json from the user, and pass it to vdsm as is. So when you see the JSON representation, you can build the json request like this: $ cat args.json { "vmID": "6e95d38f-d9b8-4955-878c-da6d631d0ab2", "checkpoint_ids": ["b8f3f8e0-660e-49e5-bbb0-58a87ed15b13"] } You need to run the command with the -f flag: $ sudo vdsm-client -f args.json VM delete_checkpoints { "checkpoint_ids": [ "b8f3f8e0-660e-49e5-bbb0-58a87ed15b13" ] } If you need to automate this, it will be easier to write a python script using the vdsm client library directly: $ sudo python3 Python 3.6.8 (default, Oct 15 2021, 10:57:33) [GCC 8.5.0 20210514 (Red Hat 8.5.0-3)] on linux Type "help", "copyright", "credits" or "license" for more information. {'checkpoint_ids': ['b8f3f8e0-660e-49e5-bbb0-58a87ed15b13']} Like vdsm-client, the library is meant for oVirt developers, and vdsm API is private implementation detail of oVirt, so you should try to use the public ovirt engine API instead.
