Hi All
I've written a new wiki page [1] for a feature we've developed, called All in One.
This allows configuring VDSM on the same host with rhevm (ovirt) automatically during
setup.
Please review and provide feedback :-)
Thanks

how are you planning to perform this check?

worth mentioning bootstrapping code was changed to allow to not reboot a
host for this.
3. "The plugin works by providing parameters, group and sequences and
adding them into the Controller object (the main object of the setup

nice - I like it is modular code.

Sounds indeed modular. Not really familiar with
the architecture of the setup process today, so I have a one question:
How easy will it be in the future to write a plugin that performs different actions?
I'm asking because of the gluster integration. They might also want such a "all
in one" feature, and in their case the CPU type is irrelevant, some of the steps are
similar, and some other steps will have to be performed, such as format partition, create
bricks, volumes and etc.
We should think about this today, as they might need this tomorrow :-)
Thank you,
Oved

today, so I have a one question:

It's quite modular and it's very easy to create another plugin.
I'm asking because of the gluster integration. They might also
want such a "all in one" feature, and in their case the CPU type is irrelevant,
some of the steps are similar, and some other steps will have to be performed, such as
format partition, create bricks, volumes and etc.

from the description in the wiki, it will by default create a local
storage DC/cluster and configure the host in it. fencing is not relevant
for local storage, as they can currently have only a single host per DC.

One thing I noticed is that you plan to install engine-core,
and then add the host using REST (sdk). Please note that
prior to starting JBoss you need to create the ovirtmgmt
bridge. If it doesn't exist when you add the host, then
it'll be created and network may be corrupted, especially
with JBoss up & running over it.

As far as I've seen in testing, the creation of the bridge was working
fine. And why would it be different between automatic and manual
creation of the host?

So far, no one created a bridge under JBoss' legs while
it's up & running. Bridge creation happens on hosts and
not in the engine-core machine. So up until now we had
JBoss up & running in his machine, and when it installed
a new host, a script would run on that new host to change
networking for the new bridge to be created. During this time
JBoss is monitoring the process from a (safe) distance.
Now, an web-app running on top of JBoss (you may know
it as engine-core) is doing network changes while the
app-server (JBoss...) is running and listens to 0.0.0.0
and maybe locally as well to specific ports. In this
situation network changes should happen only if you /know/
it's safe, or even better- do it /before/ starting JBoss.
So when JBoss starts network should be stable.
