[ovirt-users] Migration Progress Bar UI question, was Migration Progress Bar not updating

[Einav Cohen]

interesting suggestion. this will also allow tracking 
progress of tasks on multiple business entity types if / 
once supported) all at once. 
Moreover, if we will have more than one task running on 
a single VM in parallel (e.g. Host migration and Snapshot 
creation - not sure if possible today, it is just an 
example for clarification), it would be nice to display 
progress per task, rather than somehow "squeeze in" all 
of this information within the vm list somehow. 

However: I think that having this information available 
*only* in the Tasks pane (i.e. instead of within the vm list) 
is problematic at the moment, since if we have 100 migrations 
happening in parallel, tracking down the migration progress 
for a particular VM that I am interested in may be difficult. 

[this, of course, can be resolved by improving the current 
tasks-pane to allow filtering, for example]

another reason to keep this data in the vm list is the 
fact that it gives a very clear graphical indication that 
this VM is currently "going through some critical process", 
so the user can make a more educated work-flow decision 
quicker. 

I agree with your comment on the already-overloaded VMs 
grid real-estate. Note that this particular issue may be 
resolved more generically in the context of [1]. 

so to summarize: I think that the state today is reasonable, 
but can be greatly improved. I assume it will be somewhat 
improved once [1] is addressed. 

proposal for further improvement:

- have the tasks progress information available twice:

  a. [detailed information] in a Tasks context. This can be 
in either one of the following, preferably both: 

     * a global Tasks context, i.e. the Tasks bottom pane. 

     * a "local" Tasks context, i.e. only for the VM, e.g. 
a (new) Tasks sub-tab in the VMs main-tab / a tool-tip that 
appears when hovering on the Tasks indication within the 
vms list (see b. below) / etc. 

  b. [summarized (short) information, to save real-estate] 
within the VM list. This can be either one of the following: 

     * only percentage / percentage average (if multiple 
tasks run in parallel) 

     * just an icon that indicates "task(s) are running 
on this VM". 

[icon/label color may change based on the average tasks completion]

     * ...

- need to have the detailed information easily accessible via 
the summarized information; e.g. hovering on the label/icon in 
the vm-list should display a tool-tip with the full details 
(e.g. "2 running tasks: 1. migration [45%] 2. snapshot [98%]", 
can even contain graphical bars, etc.) / clicking on the 
percentage/icon will "jump" to/focus on the relevant tasks from 
the Tasks pane/sub-tab / etc.

[1] Bug 957600 - [RFE] RHEV-M should have a field/column chooser in the UI that is saved for the logged in user.
