Did you look there?
It explains that you need to post "<action/>". I don't know why this
is needed, but this
is how the API works :-)
Base on other examples, you are missing
--data "<action/>"

oVirt vms are not persisted on the host. They exist in oVirt db, and defined
on the host only when the vm is running.
oVirt API is the right place to control the system.
If you want something that is easier to script and does not require low level
API details, you can use the SDK - here is a related example:
