[ovirt-users] How to add a note to a VM

Hello, I know there are the "Comment" and "Description" columns available in many areas of the Webadmin Gui. But there are some tasks, like "shutdown VM" or "Management -> Maintenance" for a host, where I can specify a "reason" for doing that task and then a note icon appears, aside the object, with the mouse over showing the note text, like in this image: https://drive.google.com/file/d/1v3Yd2t7AtuRFMT6HPFYYZqYUmJLMHYMY/view?us... Is there a way to do it in general? So for example I have a VM and I want to put a note (for some colleague, or to remind me to do an action tomorrow, ecc...) And btw: how can I manually remove the note? Eg I shutdown a VM and fill in the "Reason" field and then in a second moment I want to remove it.... Thanks in advance, Gianluca
