[ovirt-users] Hosted-Engine with only 1-IP

[Taste-Of-IT]

Hello,

one question from a beginner. The case, i rent a server with 1 public 
IP-Address. Is it possible to setup oVirt as Hosted-Engine via ssh and 
vnc remote with only 1 public IP-Address, or need i a second public 
IP-Address for the engine? Perhaps its about an host entriy or something 
like this possible?!


Thx

Re: [ovirt-users] Where to add NFS Data Storage

[Taste-Of-IT]

Hello Joop,

ans sorry for my late reply. Indeed the docs of red hat are very good, 
if you found the right one. i worke a few weeks with oVirt and i can 
make all run, but for my personal needs, i will understand the system 
and what is made where and why. Thats why i asked a lot question about 
deeper sense...There are also lots of howtos in the net which didnt work 
any more or for diffent cases or systems.


So as i first startet with all-in-one, someone say that this will not 
longer supported at 4.x ok, so i test now the hosted-engine, but its a 
bit tricky to setup if you new and some changes came with new releases.


i actually do more than 10 installation, and learned each time i play 
with options in setup. I searched the docs too, but some things i didnt 
find. My problem is still the handling of nfs export paths and activate 
them in ovirt later.
one of my experience is: 1 path for data, 1 path for iso and all as nfs 
export, which work well. if iam in ovirt i cant activate the data path, 
while the wizard says it is allready in use.
so next installation i created same 2 paths plus one for engine which i 
take at installation for the engine. if i later in ovirt add the data 
nfs path, i suddenly see both data nfs domains, engine and data. and 
thats what i not understand?


For understanding, the storage cames though the Cluster and will used by 
the hosts, right? Or have i add each storage over the system, which will 
used in each cluster by the hosts? Or depend its on the concept of using 
the storage, e.g. storage on host or extra storage in the net?


Greetings

- the host itself needs a storage path at installation process too,

Don't know if you just want to play around with it for personal use or
if its going to be using in a production environment. Doesn't matter
whether its just one host or more than one.
If the first than try to read up on ovirt or use the redhat Rhev docs 
on

the redhat site. They are quite nice in explaining the concepts behind
oVirt.
If its the latter than I have been using/installing oVirt
for quite some time, since the 3.0 times, and offer support on it for
those in need

I have no problems trying to help off or on list and maybe its just
seeing how all fits together that will make you understand how things
work. Hosted-engine is a 'warped' concept but it really works although
there are certain pitfalls to be aware of.

Joop

ok i think to know what you mean. So my problem is to understand the

possible, because the nfs storage is provided by the engine self,
right?

that would mean, that if i have 300gb disk on host free i have to give
the engine the max size of lets say 300gb for iso and data/vms, right?
but the question remains, where should i configure the nfs storage
since i must add storage at installation on host. at engine
installation i can say no if i where ask for storage. but i have to
add the storage in webgui, but which one?

as you can see iam a bit confused.

Hello Joop,

actually right after the installation i have no storage domain. so
what have i to do in detail? my installation path at installation are
/var/ovirt/exports/data and /var/ovirt/exports/iso. the data i added
at installation for the host. at engine installation i say no to
storage domain. as far as i see and understand i have no storage
domain in cluster, also for default and those i added in installation
process of host.

so what have i todo in detail?

What I did was the following (probably missing quite a few steps)
- create (minimum) two folders, one for hosted-engine storage, one for
data storage, iso and export optional
- create exports in /etc/exports
- start nfs server
- make sure permissions are 36:36 on the exports
- start the nfs server
- check if the mounts work (problem areas are: iptables/selinux)

- install ovirt repo
- install hosted-engine
- run 'hosted-engine --deploy'
- I installed from centos-7 iso but appliance should work too, no
experience with it
- enter the correct path when asked for the hosted storage, nfs and
fqdn:/path-to-nfs-he-share
- follow the instruction, not much needs changing from the default
- Networkmanager still seems a problem, use static ip, don't try to
bridge wifi :-)
- If the engine is started using the ha-agent/broker it can take a 
while

before the webui is available
- If everything goes OK engine will claim and insert the hosted storage
domain in  the database and make it visible in the webui
- DONT use it for VMs
- create a new data domain on fqdn:/nfs/ovirt/data (or whatever your
path is)
- wait until its up
- start creating VMs

My case is a laptop running F22 with hosted-engine on it using a nfs
server provided by my F22 host, engine itself is Centos7.
So all storage is on my host but if I want I can move it somewhere 
else,

add storage from somewhere else because I'm nog using local storage
domain. Only thing is the overhead of the network filesystem that being
either NFS/GlusterFS/ISCSI.

There are some guides on how to setup oVirt using hosted-engine but to
be honest its hard to find on the current site and searching on
old.ovirt-.org doesn't work :-(

Let me know how far you get and maybe I can help you further if you get
stuck.

and thanks for your reply. Sorry its not clear enough for me. So let me

configure 2vCPU with 1vSocket? So the vSocket is like the physical CPU 
Socket while the vCPU is like the Threads of the CPU, right? Physicaly

Can i only run max 4 VMs?


in general - as many sockets as the number of cores you have
available, minus a couple for the host OS(one or two should be ok)
you can run more, but then they will compete for the core and
performance would decrease. But if those VMs are not CPU intensive it
may very well be ok (you just need to disable the default cluster
policy which limits the size to number of hosts’s cores)

[ovirt-users] Fwd: Re: Slow after add 2 Nic

Hello,
any help for using 2 nics in 2 networks?

Hello,
i simply add the nic and i think CentOS configure these by itself. Ok, i 
can change that. Short to my intentions. I want to use nic1 for my lan 
and nic2 for the wan route into the internet. in ovirt i want to install 
a firewall and configure both nics, nic for lan and nic2 for wan. in the 
other vm's i want to install only nic1 as bridge and configure the 
firwall as gateway which also service the dhcp. at all it must be safe 
that the vms cant break out of this and go around the firewall. so as i 
understand i would do this:

- set in centos nic1 as default gatway wich has 192.168.0.1 as gateway
- set in centos nic2 without default route
- add in ovirt a new network / nic
- create the vm for the firwall and assign nic1 and nic2
- in the other vms i would only assign nic1

is that the way to do or what do you think?
thx

Re: [ovirt-users] Update Self-Hosted-Engine - Right Way?

[Taste-Of-IT]

Hello Gianluca,

yes i installed the All-in-One Solution. I know the fact, that it will 
deprecated in Version 4.0, but my company is so small that it actually 
would not be profitable to use min 3 Server (2 ovirt and 1 for storage). 
i also have to migrate from another solution which doesnt support the 
free version realy good. So oVirt all-in-one seems to me a good option, 
actually, and i hope while lots of people use that, that the developer 
will have over version 4.0 a similar solution. as far as i know the 
support until 4.0 is still there for all-in-one and the date for release 
not public. so it could be at end of the year or later ... maybe ...


Ok back to the topic. No i want to migrate, i simply want to Update from 
3.6.2 to 3.6.3. Actually i do these:


- in WebGUI Admin Portal i set the Host to Maintenance Mode
- # yum check-update
- # yum update
- # engine-setup
- run through config Options
- in WebGUI run Upgrade for the Host
- after successfull Upgrade i set the Host back to active

These Steps seems in my test to work, but is that the right way for 
All-in-One ?


Many thx
Taste

Ah ok.
So you previously installed an All-in-One setup following something
like these instructions:
http://www.ovirt.org/develop/release-management/features/integration/allinone/
[2]

But this feature is deprecated in 3.6 and it should be dropped in 4.0

And you want to migrate this single host installation to an
hosted-engine one, that for a clean new install should be done with
something like this:
http://www.ovirt.org/documentation/how-to/hosted-engine/ [3]

In your case you have to migrate and follow something similar to this:
http://www.ovirt.org/develop/developer-guide/engine/migrate-to-hosted-engine/
[4]

but I think it is not so simple if you have at the end only one host
to use
You could export your VMs and the re-import them after migration and
scratch of your hypevisor.

What Joop suggested is the rpm command (adding a final "m" to rp)

But I think that actually you are on All-in-one where the engine mgmt
part is installed on the same machine that acts as the hypervisor.
Try to read the migration doc I pointed out and see if you can adapt
it to your environment (I don't know which 3.x version it is...)

HIH,
Gianluca

Re: [ovirt-users] Update Self-Hosted-Engine - Right Way?

[Taste-Of-IT]

Hello Simon,

i am new with oVirt, but are you sure, that this is the way for the 
self-hosted-engine? Because i have no commands with hosted-***. As far 
as i understand the engine runs in self-hosted-engine on same host and 
therefore there is no way to enter the vm with engine and set it to 
maintenance mode.?!

Please follow
this:

Ensure to take care to put hosted-engine in global maintenance mode
before upgrading the engine VM otherwise the HA agent could reboot it
(since it detects that the engine is not responsive) in the middle of
the upgrade with potentially really bad results.

 


1.  shutdown all virtual machines (can i do this from GUI, or
should it better be done inside the VMs?)
2.  yum update "ovirt-engine-setup*"
3.  yum update
4.  engine-setup

[ovirt-users] Understand CPU Socket Cores and VCPU

[Taste-Of-IT]

Hello,
i have a general Question about Hardware CPU, Socket, Cores and the 
VCPU, Cores per VSocket and VScoket for virtual Machines. Example i have 
a single CPU with 4 Cores and 8 Threads. As far as i understand i should 
configure the virtual machines with that number of socket as the host 
has. So in this example with max 1 Socket. How is the possibility in 
VCPUs and VCores? What is the limit in this example? Can i only run max 
4 VMs?

Hi Matthew,

i also new with ovirt, but i try to help. what for an iso_domain you

Thanks.  I will be also testing NFS, as you used in the howto you
reference, but for this phase of my testing, I want to stick with
local disk.  As such, there appears to be a bug with all-in-one
engine setup and a local disk ISO domain.  Should I report a bug for
this?  What's the right way to do that?

I was able to work around the issue by creating a new ISO domain via
the web GUI (see the local-iso-on-host.jpg attachment) and then
copying an ISO into the right place by hand with something like this
(your exact path may vary):

[host ~]# cp CentOS-7-x86_64-Minimal-1511.iso
/home/ovirt-localdisk/iso2/d61c0b87-25cd-4da0-9704-f453143daa6c/images/----/

After taking the two above-mentioned steps, I was able to successfully
attach ISOs to my VMs.

I think that you can leave the Hosted Engine VM with 4GB of ram
(minimum requirements) which will be added to the 2.5GB of RAM you're
already using.
So you'll have something like ~9 GB of RAM using it 1:1.

memory for the engine-vm, since its the same host. am i right with this? 
so what is the calculation for this?

[ovirt-users] Calculating Requirements

[Taste-Of-IT]

Hello,

i have a testsystem with 16GB RAM and ovirt as sef-hosted-engine on 
centos7. i have no vm started and the host consume 2,5GB RAM. In 
documents it is written that the engine needs aprox 3GB RAM and the 
system self 1GB RAM. At all nearly 4GB RAM. So i can use aprox 12GB RAM 
for virtual machines if i use the ram 1:1. is that a good point of 
calculation, or are there any other points to calculate?

Hello Ala,

yes i refere to vm disk size. I tried both and the result is the same 
like you described. So only extend size field is working. Yes i think 
the field should grayed out or disabled.


Thx for your replay - question is answered - happy holiday

Hello,

Are referring to vm disk size?
If so and I am referring here to the I:
I just tried both options and found that even though it is possible to 
change
the size field, the size isn't changed. Probably this field should be 
graded

out and only display the current size.
However, the "Extend size by(GB)" field does extend the disk size.

Hi oVirt users,

since a couple of days I'm struggling to install oVirt 3.6 on a CentOS 
7 server.


Here are the steps I have done to get oVirt 3.6 engine on the host.

1. Install minimal CentOS
2. update to latest version (yum update)
3. install oVirt 3.6 (yum install ovirt-engine)
4. start rpcbind (systemctl start rpcbind)
5. run engine-setup

  Configure local Engine database : True
  Set application as default page : True
  Configure Apache SSL: True
  Configure VMConsole Proxy   : True
  Engine Host FQDN:

  Configure WebSocket Proxy   : True

After the successful installation of the engine I logged into the
admin portal to add the host to the data center.

Here I entered in the following issue:
Adding the host never was successful. I found out that the firewalld
was always stopped and disabled during that process. A manual start of
the firewalld was allowing me to continue.

After that I was able to add the storage to the server.

Now I thought I will be able to install a VM into the host but it
looks like that something else is missing.
I have no options in the drop-down boxes of cluster, templates and OS.

Is anyone able to help me here?

Please note that this is my first oVirt installation.

Hi,

thank you for the fast response. I tried it and now I'm able to create
VMs in the local_datacenter.
Currently I have a ISO_DOMAIN and a local storage for the VMs.

I just tried to install a smal CentOS guest but I receive the

Any idea?

If host-deploy managed to finish, you can see its log in [1].
Otherwise
please try to (re)install the host.

Hi Didi,
ok i will have a closer look into the log. Actuall the WebGUI 
doesnt

load,
services are up and running. How can i reinstall the host? Via 
cli?

Or
do
you mean the hostsystem with installed ovirt engine? thx





Not sure I follow.

The engine runs on some machine, let's call it "the engine 
machine".

If it's a self-hosted-engine, it's running inside a VM managed by
itself.
Otherwise it's running elsewhere (on some physical machine, or 
some

other
VM).

A "Host", in ovirt terminology, is where VMs run.

Now please describe what you did, what you now try to do that 
doesn't

work, and what you can find in logs that might be related.

If you can't access the web admin ui, that's a completely 
different

problem than if you can't add a host to the engine.

Best,





Hi Didi,
as far i understand there are to ways to setup ovirt. One as
self-hosted
enginge for ha and with ovirt host in vm on storage




That's called "self-hosted-engine"


and hosted engine where
all runs on the same host.




This is called all-in-one [1].

[1] http://www.ovirt.org/Feature/AllInOne


So i setup hosted engine on same machine and in
installation process i setup iso_domain via nfs too. i have done
nothing
more yet. so as i can see and read from the manual i now have to 
setup

the
host,




No. You are not supposed to setup the host from the web interface.
I didn't try that recently, but in the past there were issues 
similar
to what you wrote below. Please follow the instructions in that 
page.
Also please note that in 4.0, allinone will be dropped. Systems 
that
wish to have everything on a single host will need to use 
hosted-engine.
Also note that people reported locking issues with local nfs 
mounts, so
it seems like the safest bet for now is to use nested kvm - run a 
VM to
play the "Host" role, and another VM as an nfs server (or iscsi), 
and
then either a third VM for the engine, or hosted-engine (meaning, 
engine

runs inside a VM running inside the first VM).

than network and than data domain and so on. now i setup the host 
and
say new, put a name inside and the fqdn of the initial host of 
host

engine
like myserver.com. after that i saw the progress which says
"installing.." i
wait several minutes and after that i got network time out and 
cant

enter
the webgui. hope that helps




Good luck,




Hi,
that sounds not good. As i understand the only way with ovirt from
Version 4
will self-hosted-engine and i have to setup all in nested-vms if i 
want

or
only can use one machine, right?



Not sure I completely followed.

allinone will not be supported in 4.

hosted-engine will be the only way to install an entire ovirt system 
on
a single machine, _supported_ by ovirt. And as I said, even this one 
will

require an external storage machine.

Of course you can use virsh/kvm or whatever other means for creating 
VMs

and use them to setup ovirt.



Ok i will have to reinstall my testsystem. Is that the way todo:
http://www.ovirt.org/Features/Self_Hosted_Engine?



Yes, but you can use the howto [1], which is perhaps more 
comfortable.


[1] http://www.ovirt.org/Hosted_Engine_Howto


So i have to install ovirt
on centos7, than create a kvm with centos for the engine than for 
the

host
and last a kvm for the nfs and data domain with centos, or better to 
use

iscsi du to performance? after that i can install the first virtuall
machine,right?



Depends on what you want to do.

BTW, I didn't mention glusterfs, mainly because I do not know it 
well,

but that's also something to consider.


sounds strange and complicated...
