Hi All,
this is the proposed new feature called instance types:
http://www.ovirt.org/Features/Instance_Types
Long story short - it should basically split the VM template into:
- "hardware profile" called instance types
- "software profile" called image
This should enable to do something like: Create a new "small" VM and attach a
disk with "RHEL + Postgres" installed.
Any comments are more than welcome!

Hi Tomas,
I like the idea in general, but for me the instance types looks like a feature that is
typical in public clouds, while in private clouds it looks more like a cool extra feature
for special cases. Therefore in my opinion it would be great to keep the old template
solution as well to keep it simple for most users. A template could be an instance type
and an image together. Only the description overlap, and that could be solved.
Thanks,
Laszlo

Hi Laszlo,
it is not useful just for public clouds - it can be pretty useful for private as well. But
to keep the previous way, it could be done this way:
- on the advanced screen (after clicking "show advanced options" you can specify
the template)
- by default you pick on basic view the instance type (e.g. HW profile) and the Image
(e.g. disk with some metadata such as OS type). But, you can select custom instance type
(equivalent to blank template) and no Image. In this case the template appears also on
basic view and you can select it.
What do you think?

New subject: [Engine-devel] Instance Types Feature
hi,
This is what I thought of:
In public clouds it is common to have pre-defined instance types e.g. amazon
small/medium/large/x-large instance, and this is what customers get even if they don't
like it. I guess this helps Amazon a lot to simplify the decision logic for vm scheduling
and pricing.
In a private cloud, you choose the resources your application needs, therefore you can
choose just as much as you need.
Of course after introducing the instance type in ovirt, you will still have control over
the instance types and create any instance type you like beyond the pre-defined types you
have in public cloud, but you will have two things to set: the instance type and the
image, which is more administration than just working with templates, while most of the
cases the templates were enough: you created both the OS image and the virtual hardware
profile it is running on. For another image and another workload, I would most likely want
to create another one that just fits the needs.
This is why I think keeping the template as an entity composed out of an image and a
instance type would be great.

gets reflected in all machines using this instance type.
This is why I think keeping the template as an entity composed out of

yep, it seems we will keep it :) It
just will be hidden in the advanced options (e.g. one more click). Sounds reasonable?

A hidden feature is a not existing feature :)
Well, the
"hide" was not a correct term :)
But where would you put it? I see the following options:
1: To the basic screen (but a bit confusing as there will be instance type and image and
this dialog should be as simple as possible)
2: To the advanced screen (let's not call it hide but make it an advanced option:) )
3: Do not add it at all (worst case)
I suppose that add it to simple screen and put the Instance type and Image to the advanced
one is not really an option as the main point of
this feature is to actually introduce the instance types as a more convenient way of
configuring the VM's HW decoupled from SW.
What do you think? Do you see any other ways? I would say that the second possibility is
not bad...
Thank you,
Tomas

New subject: [Engine-devel] Instance Types Feature
So, I had a discussion with Laszlo. Long story short, the question is:
@Andrew: Is the more basic use case to select the Template or to select the Instance Type
+ Image? Why?
We need to decide it because the more basic UC should be in basic view and the less one in
advanced (after clicking "show advanced options" button).
The concern is, that the HW is anyhow configured to serve the SW so it, in most cases of
private cloud, does not make sense to
split them. So the user will have to select two combo boxes instead of one with no added
value (e.g. RHEL63-instance + RHEL64-image).
I understand that the advantage of having the HW and SW profile separated is that you can
update the HW of all VMs created from it.
But is this the basic UC or the advanced one?
Thank you,
Tomas

Other advantage of separating the HW and SW configuration is that you
can just change the HW profile (instance type) on which you are
running, or, if the instance type changes, it gets reflected in all
machines using this instance type.

yep, it seems we will keep it :) It just will be hidden in the
advanced options (e.g. one more click). Sounds reasonable?

Subject: Re: [Engine-devel] Instance Types Feature
hi,
This is what I thought of:
In public clouds it is common to have pre-defined instance types e.g.
amazon small/medium/large/x-large instance, and this is what
customers get even if they don't like it. I guess this helps Amazon
a lot to simplify the decision logic for vm scheduling and pricing.
In a private cloud, you choose the resources your application needs,
therefore you can choose just as much as you need.
Of course after introducing the instance type in ovirt, you will
still have control over the instance types and create any instance
type you like beyond the pre-defined types you have in public cloud,
but you will have two things to set: the instance type and the
image, which is more administration than just working with
templates, while most of the cases the templates were enough: you
created both the OS image and the virtual hardware profile it is
running on. For another image and another workload, I would most
likely want to create another one that just fits the needs.
This is why I think keeping the template as an entity composed out of
an image and a instance type would be great.

New subject: [Engine-devel] Instance Types Feature
So, I had a discussion with Laszlo. Long story short, the question
is:
@Andrew: Is the more basic use case to select the Template or to select the Instance Type
+ Image? Why?
We need to decide it because the more basic UC should be in basic view and the less one
in advanced (after clicking "show advanced options" button).
The concern is, that the HW is anyhow configured to serve the SW so it, in most cases of
private cloud, does not make sense to
split them. So the user will have to select two combo boxes instead of one with no added
value (e.g. RHEL63-instance + RHEL64-image).
I understand that the advantage of having the HW and SW profile separated is that you can
update the HW of all VMs created from it.
But is this the basic UC or the advanced one?
I have checked with Andy, it seems like this:
the users complains that the "new VM dialog" has far too many options and it is
hard to start using it.
After this change, the oVirt will be shipped with preconfigured instance types (e.g.
something like small, medium, large etc)
which will pre-fill the dialog, and unless you press the "show advanced options"
you won't even know how. It should enhance the
learning curve of new users.

A hidden feature is a not existing feature :)
Well, the
"hide" was not a correct term :)
But where would you put it? I see the following options:
1: To the basic screen (but a bit confusing as there will be instance type and image and
this dialog should be as simple as possible)
2: To the advanced screen (let's not call it hide but make it an advanced option:) )
3: Do not add it at all (worst case)
I suppose that add it to simple screen and put the Instance type and Image to the advanced
one is not really an option as the main point of
this feature is to actually introduce the instance types as a more convenient way of
configuring the VM's HW decoupled from SW.
What do you think? Do you see any other ways? I would say that the second possibility is
not bad...
Thank you,
Tomas

You will still have the templates - you will be able to choose a
template which defines both. But it will be "hidden" in advanced
part of the dialog.
You are right, the simple way is pretty much inspired by public
clouds, because they do great job in making the things easy. You
basically just say you want a small machine and attach a rhel image
to it.
Other advantage of separating the HW and SW configuration is that you
can just change the HW profile (instance type) on which you are

Our plan
was to provide couple of predefined types and let user create own if needed. Custom means
an extra type where you can specify anything when creating a VM (or use a template).
A change to one of the instance type's parameter(say, mem size) will change the type
to Custom while creating a VM. Otherwise the VM will be tied to its instance type and
update to the instance type will be global and reflected in all relevant VMs.

Hi Tomas,
I've couple of comments, mainly from User POV.
Currently:
- we've many useful information, but only on Template tab. Once user
(administrator) wants create new VM, he HAVE TO go to template tab,
remember/write down name of template & then went back to VM tab & create Vm
from desired template.
New after this change:
- Administrator will go to tree - clicks few times (or just once in case is
expanded by default), then to DC then to Template tab.
Overall at lest +1 click => almost EACH time someone needs to create VM?
What if we bring these changes?
- Create VM window will show as much info about template as possible
- Description, NICs, list pf apps! (there is plenty useless space in gray
area on top of this window above/top/between {DC & CLUSTER})
- as much info as possible (VM subtab on Hosts/Templates main tabs)
- links between entities which are leading to different entities - once I'm in
template VM subtab, why I can't click to button & be transferred to VM tab to
see all info about this VM?
After mentioned changes I don't really care in which layer or how deep tabs
are. Currently we're adding/deleting tabs in each release in a loop.

Some questions:
1. Why do we need a new set of permissions for "Create Instance" and
"Instance Owner"? Aren't the VmCreator role and the UserVmManager role
enough in these use-cases? 2. iiuc, the internal implementation of instance
types and images will be done using templates. However, I guess we plan to
expose instance types and images as REST resources, right?
Thank you,
Oved

so checked this with Andy:
- Create Instance: it is a permission to actually see the instance
types in the list of instance types when creating the VM and to be
able to create a VM from that instance type
Wouldn't we want the instance types
to be public, limiting the user on resources according to his Quota?
What worries me is that you currently need VmCreator role on a DC in order to be able to
create VMs there, add disks, and etc.
So, now you would also need to have a CreateInstance permission.
And, in addition, you also need the right Quota.
Why not simplifying things, saying all instance types are public, and you only need
VmCreator role, and the Quota for your new resources?
- Instance Owner: if the user has this permission, he can edit the
fields marked as "Basic User" in the table in the wiki (but not the
others)
