I'm trying to check if a certain host can be upgraded.
1. I'm calling it through the host_service, something like:

host_service = connection.system_service().hosts_service().host_service(
host.id)
is_upgrade = host_service.upgrade_check()

To my surprise, is_upgrade is None. I expected a Boolean.

2. In addition, when trying to upgrade via:
host_service.upgrade()

I'm getting Operation Failed - and it complains there are no upgrades
available.
Alas, in the UI it shows that upgrades available and upgrade does work
through the UI.

Am I misusing the functions?
(The host is a regular host, not ovirt-node btw).

TIA,
Y.

The "upgrade_check" method doesn't return anything, it just triggers the execution of the process to check for upgrades. Then only result will be that an icon will be displayed in the UI.

That isn't very useful, to be honest, so I'd suggest to open a bug to modify this so that the upgrade runs synchronously, and so that the method returns the boolean that you expected.
