Hi Livnat,
My name is Malini Rao and I am the lead interaction designer dedicated to RHEV/Ovirt UX
from Red Hat and we have another interaction designer Eldan Hildeshiem who is also focused
on RHEV UX. I went over your feature page and in general, the GUI proposals look great. I
do have some quick feedback comments -
Will there be any predefined profiles available to the users out of the box in RHEV? Or
will they have to define their own? I am wondering if there are any common standard QoS
levels that can be predefined and the users can get a heeadstart and use or tweak instead
of defining from scratch.
VNIC level QoS dialog
1. Will the Outbound and inbound values come with some defaults? Or will they be empty? Is
there a need for any spinners or drop downs for frequently used values or is it ok to just
have fields to type in the numeric values? Also I am assuming there is some kind of
validation to ensure only numbers an be entered in these fields.
2. For custom properties, why do we have a drop down? Can custom properties defined
elsewhere be accessed here and applied? If not, then I am assuming this will have to be a
text field. Correct? Also, I am guessing if there is only one custom property field, the
[-] icon will be disabled.
Edit Network Interface Dialog
1. It will be awesome if under the Profile Field value, you can present a short summary of
the profile in gray text. alternately, there can be a little info icon which will present
this info on hover. This will help people who pick Gold know what that means vs silver or
any other profile.
Besides these specific feedback, I am wondering if any of the VM dialogs are affected by
this? Will a VNIC profile field now show up on those dialogs as well?
I see you have identified a bunch of open issues to work out and we will be more than
happy to help you with the GUI for these flows as needed. Please feel free to reach out to
Eldan and me and we can post back to the group with our work.
Thanks
Malini

Subject: [Engine-devel] VNIC profiles
Hi,
We are working on adding VNIC profiles as part of the work to add VNIC QoS.
http://www.ovirt.org/Features/Network_QoS#VNIC_Profiles
We need to define some of the system behavior followed by this change,
here is my take -
Editing a profile -
--------------------
A user should be able to edit the profile properties (including profile
name) while VMs are attached and are using this Profile (reference
should be done by id).
Changing the network though is a bit more tricky as long as we don't
have a way to distinguish between running and current configurations I
think it could be very confusing to the user. Especially since we
support dynamic wiring so the behavior IMO is unpredictable.
I think it should be blocked at this point.
Edit a VNIC / change a VNIC profile -
------------------------------------
Changing the profile a VM is using while the VM is running should behave
like dynamic wiring (changing the VM network while it is running).
Remove a Profile -
-------------------
Is only valid if all VMs that are using this profile are in status down.
It should update all VMs to point to no profile which should behave like
none network today.
I see no reason to support a profile on a none network at this point.
The above is also relevant for upgrade flow (upgrading none network to
point to no profile)
Removing a Network -
----------------------
should remove all profiles on that network
VM snapshot/import/export -
--------------------------
We should handle VMs that are pointing to a network directly for b/w
compatibility.
we need to select first profile that is on that network that the user
has permissions on.
I assume there are more, comments are welcome
Thanks, Livnat
