Wouldn't it be possible to check the response of ospd-openvas and don't raise any message if it is still busy?

Not sure what you mean. This function is checking the response from ospd-openvas. If it's still busy we don't get element VTS so we print a debug. You're saying we should just leave out the debug?

I mean we should check the response of ospd-openvas and not raise any warning. ospd-openvas should return a specific status code with a specific message in this case which should be checked instead of relying on a missing vts element.

The current log message is confusing because 1. we do expect this behavior from ospd-openvas and 2. it is an implicit assumption that if vts is missing ospd-openvas is busy.
