Re: [ovirt-users] Some questions about Ovirt REST API

[gss...@pku.edu.cn]

Sorry for one more question.

I want add an Action like .../vms/{vm:ID}/myaction
So,
1. I add api in api-model project and mvn clean install.
2. After mvn clean install my ovirt engine project. I get the generated file : 
VmResource
In that file I get 
 
Question: I cant find href  'myaction'   in GET request feedback.xml  

I must have misunderstood sth.

Re: [ovirt-users] Some questions

Hello.




 





1. How can I acces to the User Portal from a different PC of my subnetwork (appart from the one which has the engine)? IP/UserPortal doesn't work.




 

It could acces to the admin portal from another device till I installed the manager as a node. But not now...

 





2. I have Ubuntu and CentOS in a VM. I added a NIC to each one but they don't appear as a interface.




 

Solved. I tried with a different type.




 





3. Why when I try to install W10, it doesn't detect any Hard Drive ? I added the floppy disk as it's explained on the web guides.




I'll test it in some days.

 

Thanks everybody.

Re: [ovirt-users] Some questions

[Wesley Stewart]

In addition to the previous post, oVirt requires you to use a DNS entry,
not an IP address to access the web interface.  If you don't run your own
DNS server, you can simply edit the host files on the client PCs.  This is
quite easy to do.  For example, just Google "edit host file on Windows".

Did you add the vnic after the installation?  The Linux distros are pretty
good when doing the install of detecting the NICs, but if you add them
later you may have to enable them afterwards.  Try running "sudo nmtui" and
see if you can enable it that way.  Otherwise you will Need to activate it
manually.

Lastly, windows was tricky for me at first.  Have you downloaded the oVirt
driver ISO?  Make sure that you have downloaded this and have it available
for oVirt vms to use.  During the windows install, you will have to use the
"change disk" or "change CD" button in the console once you get to the
point where you can choose your driver's, load the correct drivers, and
then switch back to the windows iso and continue the install.

https://www.ovirt.org/documentation/how-to/virtual-machines/create-a-windows-7-virtual-machine/

I hope this helps!  Once I am next to a computer I can answer more fully if
necessary

There are 2 scenarios:

- engine is kept separate from oVirt infra itself. In this case the related
sw components should be installed on a server that is not one of the nodes
an not one of its guests. This server could be a physical server or a
virtual server (in this second case part of a different virtual
infastructure, oVirt or not oVirt)
Eg: I have a vSphere environment where I configured a CentOS 7.3 VM and on
it I installed the engine sw components for managing an oVirt
infrastructure. So this vSphere virtual machine is my "oVirt management
engine", using your words.
HA of this server and its backup/restore policies naturally inherited from
what offered by VMware and its agents

- engine is itself a VM of the oVirt infrastructure that it has to manage
This kind of environment is known as Self Hosted Engine environment
The technological approach is similar to the one described here for VMware:
https://kb.vmware.com/selfservice/microsites/search.do?language=en_US=displayKC=10087

There is also the choice to use an already set-up virtual appliance as done
in VMware:
https://docs.vmware.com/en/VMware-vSphere/6.0/com.vmware.vsphere.vcsa.doc/GUID-223C2821-BD98-4C7A-936B-7DBE96291BA4.html

See here for oVirt:
http://www.ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_Engine/

and here for RHEV:
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html/self-hosted_engine_guide/deploying_self-hosted_engine

When you use Self Hosted Engine Environment, the guest used as engine mgmt
virtual server is not "owned" by a particular host.
In a certain moment in time it will run on Node1 or Node2 but it can be for
example live migrated if you desire.
A subset of the Hosts of the infrastructure can be selected as "Hosted
Engine" Hosts, so to be able to guest the engine VM
You should define at least more than one hosts of this kind, if you want
redundancy for the engine vm in this case.

See here the RHEV doc to add a new host and set it as an "hosted engine"
host, I don't find the related part in oVirt docs (link missing...)

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html/self-hosted_engine_guide/chap-installing_additional_hosts_to_a_self-hosted_environment
Feel free also to RTFM.. both oVirt and RHEV, they are done well in my
opinion, starting here:
https://access.redhat.com/documentation/en/red-hat-virtualization?version=4.1/

the match is not 1-1 between oVirt and RHEV same versions but I would say
at least 90%

Based on the answers above, this applies only in self hosted engine
scenario, and as written above, you should take care of setting more than
one host as "hosted engine" host, so that the HA of the engine VM will be
guaranteed.
I opened a bug to propose this to be the default in case of self hosted
engine environment.
See here
https://bugzilla.redhat.com/show_bug.cgi?id=1399613

and also this related one:

Re: [ovirt-users] Some questions about Ovirt architecture

[Lev Veyde]

Hi Khoi,

Node is the hypervizor which can run many guests (VMs).

We support a feature call Hosted-Engine, which allows the Node to run the
Engine (the oVirt Manager) as a special type of highly-available VM on the
Node(s), that it will manage.
( https://www.ovirt.org/documentation/how-to/hosted-engine/ )

That Engine manages all Nodes that are added to it, and all VMs that they
run.

In case e.g. Node1 fails you can simply start the VM on Node2, (as long as
shared storage is used), in case of Hosted-Engine it will happen
automatically - as long as you installed it on multiple nodes, which is the
recommended deployment.

Hope that helped, if you have any further questions please do not hesitate
to ask,

Thanks in advance,

[ovirt-users] Some questions about Ovirt architecture

[Khoi Thinh]

Hello,

My name is Khoi. I'm totally new to Ovirt and i'd like to know some
knowledge related to Ovirt's architecture as well as how it works.
As far as i understand, in each "Node" we can have many "guest".
My questions are:

1.We need to install Ovirt management engine in order to manage system. But
that engine would be installed on "Node" or can be installed on "Guest"?

2.Let's say i have 2 "Node" with 4 "Guest" in each "Node"
It would be something like this
[ ■  ■] Node 1
[ ■  ■]

[ ■  ■]  Node 2
[ ■  ■]

If the management engine can be installed on the first guest of Node1, from
that we can manage everything in Node1 and Node2? Or we just only manage
the other guest in Node1?

3.Regard of High availability of Ovirt
If the first guest of Ovirt1 (which we install management engine on) went
down, what would happen? We can pull a image from Shared Storage and use it
to deploy a new management engine on other Guest? (On Node1 or Node2)

Best regards,

this is not true for vdsm 4.14. on ovirt-engine 3.3.z
see this bugzilla entry:
https://bugzilla.redhat.com/show_bug.cgi?id=1120267

 It depends on the supportedENGINEs which getVdsCaps will return.
 Generally, VDSM for 3.x should keep supporting its 3.x previous minor 
 versions.

 Subject: [ovirt-users] Some questions
 
 Hi, i installed Engine 3.0 and Node Ovirt 2.6, but it seems very unestable.
 Sometimes machines doesnt starts, nodes doesnt vinculate or UI doesnt work
 fine. I have only 2 nodes and storage its on the same physical machine than
 engine.
 
 -¿Does Node Ovirt 3.4 work with Engine 3.0?
Engine 3.0 should support backward compatibility for ovirt 3.4. You can verify 
that on the node be executing the following command : vdsClient -s 0 
getVdsCaps (-s for secure),
There, you should see a supportedENGINEs list.
 -¿Its necessary shutdown Nodes to do engine upgrade?
no, but take in consideration that after upgrade, those hosts might get into 
non-operational state, in case VDSM version should be upgraded also.
 -¿Are there any problem having the same physical machine for engine and
 storage? ¿what are advantages have on diferents machines?
There is no limitation of doing that,
it's simply a question of the architecture you want to support.
Separating the engine from the Storage server, might be useful to make it more 
high available.
 
 Thank you

It depends on the supportedENGINEs which getVdsCaps will return.

Subject: Re: [ovirt-users] Some questions

hi,

my concern is that we have some critical MV. If the node enters into non
-operational state after upgrading the engine. Will be machines up?

I've been searching and upgrading should be progressive, 3.0 to 3.1, 3.1 to
3.2 
I guess if the nodes VDSM update to the latest version, and later I'll update
the engine version by version nodes wouldnt enter on non-operational state
and not suffer any court in MV. Am I right?

Thank you very much for your help
