[ovirt-users] New host cannot connect to master domain

[ovirt--- via Users]

Hi, 

i just installed a new host, which cannot connect to the master domain. The 
domain is an iscsi device on a nas, and ovirt is actually fine with it, other 
hosts have no problem. I'sure , I#m just overlooking something. 

What I see in the log is:

The domain a15496dc-c241-4658-af9d-0dfe11783916 definitely exist, and works on 
other systems.

THe new host can acces the iscsi targets, and i am able to log into them.

Any one who knows, which blinder I have to remove, so I see the actual problem?

Thanks and best regards

[ovirt-users] Advice on upgrading oVirt 4.2 CentOS 7.x cluster to oVirt 4.5 Rocky Linux 8.9

[ovirt]

I have multiple aging clusters that I now need to upgrade both the host OS and 
the oVirt release. I have seen the notes about upgrading 4.2 to 4.3 and then 
being able to upgrade to 4.5, but what's not so clear is how to upgrade the 
host nodes' OS versions. After thinking about it, I wonder if this method is 
sane. Any advice or guidance is greatly appreciated.

1) spin up a new cluster running oVirt 4.5.x on the latest Rocky Linux release.
2) shutdown VMs on the original cluster
3) detach the domain storage
4) snapshot the domain storage (for rollback)
5) import the domain on the new cluster.
6) reload the OS on the original cluster to the new OS release (no local 
storage)
7) add those hosts to the new cluster

[ovirt-users] Importing ubuntu cloud image's failing

[joel+ovirt]

Hi Folks!

TL;DR: Anyone else in the user group here also using ubuntu cloud images? Have 
you had any luck?

I finally completed the 4.5.4 upgrade and started down the next series of steps 
to deploy some newer ubuntu images, however the import of the cloud image OVA's 
doesnt function or at least not as it has previously, using the same method as 
the person here: 
https://medium.com/@dsykes012/how-to-import-an-ova-into-ovirt-4-4-2925cd89d3c3 
and im using the Ubuntu Lunar image here: 
https://cloud-images.ubuntu.com/lunar/current/lunar-server-cloudimg-amd64.ova

The UI eventually informs me: "Failed to import Vm 
ubuntu-lunar-23.04-cloudimg-20221227 to Data Center Default, Cluster Default"
Then, looking into this on the hypervisor that was performing the task, I found 
the import log which didnt seem to give me an indication of an obvious failure. 
(ill attach the log here somehow soon)

[ovirt-users] oVirt 4.4.10 -> 4.5.x RPM upgrade problems

[joel+ovirt]

Hi folks!

I've have a oVirt 4.4.x installation running for 453 days now without issue. 
Now that I had some time over the holiday, I thought it would be good to 
upgrade it to the latest 4.5.x, however im getting stumped on an upgrade step 
which upgrades the engine setup: https://pastebin.com/mxf6E1R9

A small snippet of the paste-bin here:

Any help here is appreciated

[ovirt-users] Re: vdsmd crashes with sigsegv

[ovirt--- via Users]

Hello Albert, 

thanks, and sorry for the late response.

On Sept. 26 vdsmd went down on the host again. (didn't monitor properly, so, 
only now, I realized it was down:)

This time I could not find any segvs in the logs.

When did it start?
We used until  now, 4.3, and then upgraded first to 4.5.1 (through 4.4), as 
described in the documentation. Until then, we never encountered crashes of the 
vdsmd. Only ony after going to 4.5.2 and switching to compatibility level 4.7, 
random crashed of the vdsmd happen.

The Ovirt engine, btw. is on a seperate Virtual machine, outside of the ovirt 
cluster.

On the host ,/var/log/vdsm/vdsm.log:
I only can see, logging stoppped, and after restarting vdsmd, it started again. 
Also, after restarting vdsmd, all Virtual machines on that host are shown with 
the proper running state.

[ovirt-users] vdsmd crashes with sigsegv

[ovirt--- via Users]

Hello,

since upgrade from ovirt 4.3 to 4.5., I encounter problems with one host. vdsmd 
permanently crashes after a while and it tells me, a segmentation violation is 
the cause.
As result, it becomes unresponsive to ovirt-engine.

Environment:
rocky linux 8.6, up to date
ovirt 4.5.2; 
One datacenter, compatibility level 4.7
The ovirt engine is on a seperate vm outside of ovirt. 

Any one else had that problem, or a has a tipp, where to start investigating 
the problem?

Thanks and best regards

Steffen

[ovirt-users] Re: Ovirt engine service fail to start after upgrading from 4.4.9 to 4.4.10

[gantonjo-ovirt--- via Users]

Problem solved. Reason was a fail at engine-setup. 

Engine setup showed cluster not in Global Maintenance mode, even if the cluster 
was indeed in Global Maintenance. Had to force engine setup by using a hint 
from https://www.ovirt.org/media/Hosted-Engine-4.3-deep-dive.pdf, Major issues 
4.

After this, I hit the "internal server error" problem, which I solved by 
downgrading postgresql-jdbc:

$ dnf downgrade postgresql-jdbc 
$ systemctl restart ovirt-engine

[ovirt-users] How to add an AlmaLinux 8 template?

[ovirt . org]

Hi, I'm looking for instructions on how to add the AlmaLinux template, resp. I 
can create and seal a template as an image. but I'm interested in how to do it 
via cloud instances of qcow2 and cloud-init in the 
sense:https://wiki.almalinux.org/cloud/Generic-cloud-on-local.html#almalinux-guest-os-support

I can't find the instructions ideally step by step.

Thanks you very much for support and advice.

[ovirt-users] How to find out I / O usge from servers

[ovirt . org]

Hi everyone, I would like via API, or. pull information about I / O usage by 
individual servers directly from the postre database. But I have a data 
warehouse turned off for performance reasons. Is this information collected 
somewhere so that I can collect it from somewhere in my external database or 
read it from the virus database?

Thanks for the information.

Hi,

I have ovirt version: 4.3.4.3-1.el7 I can't find in the documentation how to 
set up a server disk profile during creation via the REST API. If it didn't 
work during creation, then it doesn't matter later after creation.

How to please set up a disk profile server via REST API?

Thank you.

https://ovirt.mydomains/ovirt-engine/apidoc/#/ is not working (page is blank, 
has ovirt horizontal menu, but content is empty).

You may mean the page 
https://ovirt.mydomains/ovirt-engine/apidoc/#/services/disk/methods/update

It works for me, but the information I see on it seems insufficient (unusable) 
to me:

update

This operation updates the disk with the appropriate parameters. The only field 
that can be updated is qcow_version.

For example, disk update can be done using the following request:

PUT /ovirt-engine/api/disks/123

With a request body like this:


  qcow2_v3


Since the backend operation is asynchronous, the disk element that is returned 
to the user might not be synced with the changed properties.

I have HTTP Error 400: Bad Request  Request syntactically incorrect. But syntax 
is OK:

[ovirt-users] Re: How to reduce load during create VM

[ovirt . org]

Hi, no, we don't use bit cloning via "clone" function, but we use templates as 
a raw format template.

When creating a VM through this template, the server load will increase a lot.

We want to minimize this sharp increase during the establishment. We are 
willing to wait longer to set up the server.

Hello to everybody,

for about an hour I have stuck my nose in the ovirt and rhev documentation, but 
I still can't understand how to use the REST API to change the disk profile and 
nothing the server profile.

Ideally, how to set it for them when setting up a VM.

Thank you so much for the advice.

Thanks for your answer. 

Yesterday we removed all content from /rhev/data-center/mnt/blockSD/* on our 
nodes (in Local Maintenance mode) and manually updated the nodes with "dnf 
update". After a reboot and a night's sleep, all 12 nodes are reporting up to 
date status. 

That is, we are now on 4.4.2. Looking forward to see the error corrected in a 
future release.

[gantonjo-ovirt--- via Users]

Hi, Didi.

The command "find / -xdev -path "*/dom_md/metadata" -not -empty -not -type l" 
shows no storage domains, so I guess this would solve the "false positive" list 
of storage domains that are not really mounted to the node we want to update.

[gantonjo-ovirt--- via Users]

Hi again.

Just did a test. I unmapped the node from the iSCSI SAN and rebooted the node. 
After reboot, the storage domains still where listed as / storage domains. In 
other words, this was not a solution.

[gantonjo-ovirt--- via Users]

Hi, Didi.

Thanks for your answer. Unfortunately the suggested command shows the same 
storage domains as I listed above. The node is in Maintenance (as it would be 
when Installing an update from the GUI). None of these storage domains are 
mounted on the node ( at least not visible when running command "mount"), thus 
I am not able to unmount them. I guess they are visible to the node's OS due to 
the fact that they are iSCSI domains, even if the node itself makes no use of 
them.

That said, looking at the files listed by the find command you gave me, the 
storage domains all have links to non-existent /dev/ locations, like the 
following:
/rhev/data-center/mnt/blockSD/0d57fcd3-4622-41cc-ab23-744b93d175a0/dom_md/:

ls: cannot access '/dev/0d57fcd3-4622-41cc-ab23-744b93d175a0/ids': No such file

I guess I can remove the export from the iSCSI SAN towards the node, reboot the 
node and then try to upgrade the node via "dnf update". However, the node will 
then not be able to serve the storage domains to it's VMs when taken out of 
Maintenance.

[ovirt-users] Upgrade from ovirt-node-ng 4.4.1 to 4.4.2 fails with "Local storage domains were found on the same filesystem as / ! Please migrate the data to a new LV before upgrading, or you will los

[gantonjo-ovirt--- via Users]

So, we have a cluster of 3 servers running oVirt Node 4.4.1. Now we are 
attempting to upgrade it to latest version, 4.4.2, but it fails as shown below. 
Problem is that the Storage domains listed are all located on an external iSCSI 
SAN. The Storage Domains were created in another cluster we had (oVirt Node 4.3 
based) and detached from the old cluster and imported successfully into the new 
cluster through the oVirt Management interface. As I understand, oVirt itself 
has created the mount points under /rhev/data-center/mnt/blockSD/ for each of 
the iSCSI domains, and as such they are not really storaged domains on the / 
filesystem.

I do believe the solution to the mentioned BugZilla bug has caused a new bug, 
but I may be wrong. I cannot see what we have done wrong when importing these 
storage domains to the cluster (well, actually, some were freshly created in 
this cluster, thus fully managed by oVirt 4.4 manager interface).

What can we do to proceed in upgrading the hosts to latest oVirt Node?

[ovirt-users] oVirt disk disappeared after importing iSCSI domain

[gantonjo-ovirt--- via Users]

Hi all oVirt experts.

So, I managed to f.. up a VM today. I had one VM running on a oVirt 4.3 
cluster, where the disk was located on an iSCSI data domain. I stopped the VM, 
put the storage domain in maintenance mode, detached adn removed the storage 
domain from the ovirt 4.3 cluster.

Then I imported the storage domain to our new oVirt 4.4.1 cluster, let the 
process convert it from V4 to V5 format and activated the storage domain in the 
new cluster. Entering the information page for the imported storage domain, I 
expected to see "Import VM" and "Import Disk" menus, but these menues did not 
appear as they did for other storage domains that I successfully had moved from 
old to new cluster.

Clicking "Scan Disks" did not help either.

So, now I am stuck with a storage domain where the VM's disk is located, but 
oVirt is not able to see the disk.

What can I do to recover the lost disk from the storage domain? Any CLI 
commands available in ovirt 4.4.1 would be nice.

Thanks in advance for your quick and good help.

[Ovirt User]

I am performing a new install of 3 nodes
ovnode1 - 3 disks,install on first two disks
ovnode2 - 3 disks,install on first two disks
ovnode3 - 3 disks,install on first two disks

Storage network interfaces are configured with 192.168.xxx.10 no gateways 
configured for this network
Data network interfaces are configured with 10.3.x.10

When i run the wizard it always fails. All 3 hosts are running the latest 
stable (4.3.9). I have attached the log files from the runs on these hosts

So I think I fixed the option.  I created a sanlock user (179) on the NFS
server, share option also needed to use  no_root_squash.

the error means sanlock cannot write a resource on our device. Please
check 
you have proper permission on your NFS (has to be writeable by uid:guid
36:36) 
and eventually check /var/log/sanlock.log if there are any details

[ovirt-users] gluster

[mailing-ovirt]

Hi, 

 

I see options to deploy ovirt with gluster during the initial rollout,
however I can't seem to find information as to how I can add it following a
non gluster initial setup: 

 

GlusterFS Version:

[N/A]

 

Thanks

[ovirt-users] Re: network config change

[mailing-ovirt]

So in the case here, the work was already started outside of the ovirt engine 
UI.

I inherited the problem, so far I've made sure to point the em1,3 to the bond0, 
confirmed it was working (in mode 4, lacp), pointed the bond0 to the ovirtmgmt 
bridge.  Now the current setup uses dhcp and the IP address is successfully 
assigned.

One of the issue I'm seeing right now is that the hosted engine VM will not 
start.  So I started looking a bit further and I can see that route has some 
issues: 

192.168.20.0/24 dev em1 proto kernel scope link src 192.168.20.108 
192.168.20.0/24 dev ovirtmgmt proto kernel scope link src 192.168.20.108

The first line prevents the host from talking to it's default gateway (20.1) 
because it's using em1 which has no IP (part of bond0) 
If I remove the line from the routing table, I can successfully ping the 
default gateway through the ovirtmgmt interface.

I can't figure out how to prevent the system from recreating the first line 
during a reboot.

I don’t know if this is one of the reason why the engine fails or not, but 
since the ovirt startup process seems to validate ping, when the services are 
starting during boot time, they'll fail because that route is re-added.

Thanks again

Simon

All modifications should be done via oVirt Engine, e.g. in Administration 
Portal via Compute > Hosts > hostname > Network Interfaces > Setup Host 
Networks because this way the change will be rolled back automatically on 
failures.

Because this change modifies many aspects of the management network, I would 
recommend to add a temporary second host, migrate the hosted Engine on this 
second host, and put the first host in maintenance and migrate back to the 
first host after the change succeeded.

[ovirt-users] network config change

[mailing-ovirt]

Greetings,

So we have a single hosted engine ovirt box deployed.

When this was deployed, the network requirements were poorly determined and
there was no port teaming or any vlan configuration.

now we need to change that.  

I have searched all over for any form of procedure or guide as to how we do
this.

in summary: 

I need to go from a setup that uses em1 as it's default device and gateway
to a setup where em1 and 3 are bonded into bond0 and now use that instead.

 

As for the vlan we could live with keeping the native vlan configured on the
cisco side for management and only add extra ones for VMs.

any assistance as to what I need to go through from a bash shell would be
appreciated.

thanks

Simon

[ovirt-users] Re: Hosted Engine Storage migration

[joel+ovirt]

Thanks for the reply! Sorry, it's been a while for my response.

I presently have 3 hypervisors in this environment - do I need to remove one of 
the hypervisors from the cluster and use that to run the `hosted-engine 
--deploy --restore-from-file=` command? or can this be done completely in-situ 
with a running hosted-engine running?   I'm really unclear about where to start 
and the docs vary in description.

Thanks for your help!

I'm still looking for an answer here - do I shut down my existing hosted VM and 
follow:
https://bugzilla.redhat.com/show_bug.cgi?id=1409112#c12 ?

will I need to provision this on a new piece of metal that will be added to the

[ovirt-users] Hosted Engine Storage migration

[joel+ovirt]

Hello listmembers!

I'm in search of some steps to use to migrate my Hosted-Engine from one NFS 
storage domain to another different NFS storage domain. One of the possible 
ways to accomplish this task may already be a feature with oVirt 4.1, I'm using 
4.2

https://lists.ovirt.org/pipermail/users/2017-January/078739.html (New feature 
in 4.1?)

Will someone elaborate the steps to use this new feature and how I could use it 
to accomplish this task? the bug link in the email linked above has a comment 
(https://bugzilla.redhat.com/show_bug.cgi?id=1409112#c12) - does this mean I 
need to redeploy the hosted-engine? I'm not able to follow as I'm new to oVirt 
and still learning the ins and outs and design if I'm on the wrong path here 
please correct me.

Thank you,

-Joel

[ovirt-users] Desktops as Nodes and Client?

[gilbert . drew+ovirt]

Hi, 

I'm starting to look at oVirt to help with a datacentre consolidation project 
to drastically reduce the number of physical servers and it seems like a great 
fit.

As an added bonus, it looks like it might help solve some desktop management 
challenges we have.  Since the desktop PCs are reasonably powerful, what I 
would ideally like is for them to be nodes, each capable of running a single 
templated VM accessed by the local user.

I can only seem to find documentation relating to standard VDI, i.e thin 
clients and fat servers.  As I'm trying to reduce the number of servers, this 
is not ideal.

Does anyone know of a similar setup or can provide some pointers?

Thanks

Hi all,

after rebooting the ovirt-engine (4.2) i'm unable to log in to the Admin-portal

The error disappears after putting in the credentials.
Irestarting the ovirt-engine service of the whole (CentOS) VM wouldn't fix it.

I smell an issue with the Ansible var file we use to pass the password
into the job. We should probably base64 encode it or something.

With DHCP, the deployment failed when it was trying to add the gluster 
host.

Once I changed the engine to static, the deployment passed.


DHCP is tricky as you need to make sure that the FQDN always matches
the same VM (proper MAC, DNS and DHCP reservation come into play). But
this is the default for all installs I did and always worked fine.

We had a bug in the past (

I have now re-installed ovirt node on all 3 hosts.
I will double check that hosts can resolve each other.

All hosts should correctly resolve the engine VM fqdn, the engine VM
has to correctly resolve the address of all the three hosts.

Any other advise (or things to check) before I re-try Hosted Engine
Setup?

Nothing special on my side.

With DHCP, the deployment failed when it was trying to add the gluster 
host.

Once I changed the engine to static, the deployment passed.

Also Squeakz (on ovirt channel - IRC) said he has also seen the problem 
with dhcp.

Do not:

-use special characters in any of your passwords - letters & numbers

We had a bug in the past (
https://bugzilla.redhat.com/show_bug.cgi?id=1528253 ) but we never
really reproduced it, better to double check.
Can you please provide an example of password that make it failing?


-hosted engine vm - assign static IP, no dhcp reservation.


I'm pretty sure that DHCP based configuration are correctly working,
I'd suggest to double check your DHCP server.

All hosts should correctly resolve the engine VM fqdn, the engine VM

Any other advise (or things to check) before I re-try Hosted Engine

Not sure if this would have anything to do with that error on the 
previous attempt.
Even though network config files (in /network-scripts) are set to 
"ONBOOT=yes"
After a reboot, I still need to issue "systemctl restart 
network.service" otherwise I can not connect to any the 3 hosts?

it overwrites my engine IP entry from 10.50.235.x to 192.168.xxx.x

The same thing happens whether I set the engine IP to Static or

Any ideas it "insists" on using "vibr0" instead of "eno1"?

Hi,

That bootstrap VM runs over default natted libvirt network, that's
why you see vibr0 and 192.168.xxx.x at that stage.

[ovirt-users] Re: Hosted Engine Setup error (oVirt v4.2.3)

[ovirt]

I will get the logs.

Here is the exact error message:

Simone, unfortunately I deleted that install after it failed.
I can re-run the install based on the df -h (see previous post) or I
can change disks & increase the size of /var then re-run the

What do you think?
The error I was getting said it could not find the hosted engine at
vibr0 on 192.168.xxx.xx


On my opinion you could simply retry.
Please share your log file it fails again.

I get an error saying the hosted engine setup is "trying" to use
vibr0 (192.168.xxx.x) even though I have the bridge interface set
to "eno1"

Regardless of whether the Edit Hosts File is checked or unchecked,
it overwrites my engine IP entry from 10.50.235.x to 192.168.xxx.x

The same thing happens whether I set the engine IP to Static or
DHCP (I don't have DNS, I'm using static entries in /etc/hosts).

Any ideas it "insists" on using "vibr0" instead of "eno1"?

Hi,
up to this point is absolutely fine: in the new node zero deployment
flow, hosted-engine-setup bootstraps a local VM with an engine there
to use that engine to configure the rest of the system (storage,
network...).
That bootstrap VM runs over default natted libvirt network, that's
why you see vibr0 and 192.168.xxx.x at that stage.

If you are facing any issue, it's definitively not there.

Yes, the blog post describes the 4.2.{0,1} behaviour while the local
VM is a change introduced in 4.2.2.
I faced a similar error and in my case the VM creation failed
because
there was not enough space in /var/tmp. It wasn’t a problem
before,
because the engine VM was created directly on top of a gluster
volume.

It’s temporary, so you can add a disk and mount it into /var/tmp to
complete the installation and remove it when finished. The VM is
created locally, then moved to gluster and started with its final
configuration.

My 3 hosts have a 64GB SSD for the oVirt node install and a 2+TB SSD 
RAID for the gluster portion.
If the hosted engine vm does not run on the gluster volume that means I 
don't have enough space on the 64gb disk?

it overwrites my engine IP entry from 10.50.235.x to 192.168.xxx.x

The same thing happens whether I set the engine IP to Static or
DHCP (I don't have DNS, I'm using static entries in /etc/hosts).

Any ideas it "insists" on using "vibr0" instead of "eno1"?


Hi,
up to this point is absolutely fine: in the new node zero deployment
flow, hosted-engine-setup bootstraps a local VM with an engine there
to use that engine to configure the rest of the system (storage,
network...).
That bootstrap VM runs over default natted libvirt network, that's
why you see vibr0 and 192.168.xxx.x at that stage.

If you are facing any issue, it's definitively not there.


Yes, the blog post describes the 4.2.{0,1} behaviour while the local
VM is a change introduced in 4.2.2.
I faced a similar error and in my case the VM creation failed because
there was not enough space in /var/tmp. It wasn’t a problem before,
because the engine VM was created directly on top of a gluster volume.

Re: [ovirt-users] Storage Hardware for Hyperconverged oVirt: Gluster best practice

If a disk fails (aka node fails) assuming no RAID, once the disk gets 
replaced, the node will rebuild?

Is that what will happen or am I over simplifying?

Without local node replication (RAID), a failed disk == a failed node.
This may or may not be acceptable.

From Yaniv:

 I think there are two interesting questions here:
1. Why would you want RAID? Your data is replicated already on other
Gluster nodes. RAID writes will wear out the SSDs earlier and RAID
'wastes'
additional space. The reason may be because you don't want the node to
go
down in case of a single disk malfunction. Fair - but is that the
case?
2. I think HW RAID should be higher performing, but that's about it.

Re: [ovirt-users] Hardware for Hyperconverged oVirt: Gluster storage best practice

I think just defining each SSD as a single Gluster brick may provide
the best performance for VMs, but my understanding of this is
theoretical, so I leave it to the Gluster people to provide further
insight.


Pardon my lack of knowledge (I'm an oVirt/Gluster newbie).
I assume the SSD-to-single-Gluster brick can be done using gdeploy in 
oVirt?

Yes, it is for a HC setup of both oVirt & Gluster.


..it really depends on your budget,

I would like to enhance the performance.


Makes sense (I could not see the rear bays - might have missed them).
Will you be able to put some SSDs there for caching?

This the correct part # 
https://www.supermicro.com/products/chassis/2U/216/SC216BE26-R920LPB

In all the oVirt docs/videos, no one mentioned using SSD for caching?
Therefore I was not planning on caching.

Re: [ovirt-users] oVirt install error

I found another bug that is related to this problem: 
https://bugzilla.redhat.com/show_bug.cgi?id=1449217
On the initial oVirt install, the gdeploy version is 2.0.1, which causes 
the problem stated in bug # 1449217
After upgrading gdeploy to 2.0.2, you are left with the problem I 
described in my original post.

Re: [ovirt-users] oVirt install error

[ovirt]

I just used all the default setting installing from the iso.
ansible v2.3.0.0
gdeploy v2.0.2

just wondering how did this change happen. I will install with the iso

have few questions. Can you please tell me what is the version of
ansible and gdeploy you have on the node ?

Re: [ovirt-users] Nested KVM for oVirt 4.1.2

[ovirt]

Well you can always run the engine on a physical node directly too.
The question is why would you want that when hosted engine gives you
fail-over and reliability features.


Failover & reliability are definitely worth having


So I would install Node on all four hosts, enable all of them for
hosted engine and enable three of them for Gluster if hyperconverged
is what your want.


Hyperconverged is what I want.
There does not seem to be a good reason to have a 4th node, so I'll take 
your advice & go 3 nodes + hosted engine.

Hosted engine runs as VM on one of the hosts. But not necessarily on
the first one (it can even move if it decides so).


Why can't the hosted engine run on its own host?

Please note Fedora support within oVirt project is a best-effort

There's no testing of oVirt on Fedora done by the core development
team.
That said, I would be happy if you contribute fedora testing :-)

I'm not sure to understand what you're looking into now since you 
talk

about real hardware and VMs in the same sentence.
Suggested minimal deployment is 3 real hardware hosts as hypervisor
nodes and hosted engine with hyperconverged deployment.
You can use oVirt Node iso in order to do the whole deployment using
cockpit.


What is the install process?

Sandro,
If & when one decides to "graduate" & use real hardware, what is the

The install process depends on how you want to design your lab .
You can have a small deployment with just 3 hosts in hyperconverged
setup or a large datacenter with 200 hypervisors and one or more
dedicated SAN for the storage.
If you go with an hyperconverged setup, you can install oVirt Node
on
3 hosts and then on one of them use cockpit to deploy gluster and
hosted engine on top of it in hyperconverged mode.

You can find an installation guide here:
http://www.ovirt.org/documentation/install-guide/Installation_Guide/
[1]

Is the gluster part still automated or that has to be done
manually?

If you go with hyperconverged mode it's now automated. You can find
more info here:



http://www.ovirt.org/develop/release-management/features/gluster/gdeploy-cockpit-integration/


[2]
Sahina, please ensure above link is updated. I see it shows the
feature still in WIP while it's been released.

Another question, what type of use cases & jobs is oVirt being
deployed in & how are people getting tech support?

About use cases for oVirt you can find some examples here:
http://www.ovirt.org/community/user-stories/users-and-providers/ [3]
If you want dedicated support, I would recommend to get a Red Hat
Virtualization (which is oVirt with technical support and some
additions) subscription getting Red Hat support.
Another place to get support if you stay with oVirt is the
community:
this mailing list, the IRC channel and social media, have a look
here
