you don’t have to, but you’ll get a better, cleaner, template if you’ve been 
using the original image before (added accounts, installed stuff…things people 
usually do when preparing a template:)
we’re looking into integrating it into UI, as it is quite easy to omit a thing 
or two when sealing it manually

It may make sense to use it for initialization during deployment as well as a 
replacement of cloud-init not requiring you to initialize it by running it. You 
would have to do it yourself, making sure the image is not in use while the 
operation is ongoing.
I think it would also be nice to completely integrate it into “create VM from 
Template” flow. You would have a ready-to-go VMs customized at the time of 
creation already, instead of relying on runtime cloud-init

Hi,
if you look for a one-time boot off PXE, and then from hdd after installation 
finishes (which is the most frequent use case), you can use “Run Once” to 
override the “default” boot order. Instead of modifying the VM configuration 
twice.

Nevertheless, the above should work, so I would start checking if the VM is 
indeed configured correctly (bug on ovirt side) or we create it ok but there’s 
a bug in lower layers (libvirt, qemu, ipxe). If you can check the VM in UI 
there is a “VM Devices” subtab new in 3.6 which can tell you if it even has a 
NIC attached; and there is the final libvirt domain xml being logged in 
/var/log/vdsm/vdsm.log when you launch the VM - there you can doublecheck the 
VM is started as expected

Any improvement inside the gui is welcome.
Yes, in my template I already created personal users that are then able to
authenticate themself with public key in the deployed VM without any
problem and I have also Oracle client installed with a specific HammerDB
configuration file.
So the path is the one you suggested.

Re: [ovirt-users] FW: Engine upgrade error

[Frank Rothenstein]

Hi,

I found a "workaround" for my problem. In the release notes is noted
just to yum update "ovirt-enigne-setup*"
I did a yum install instead an was then able to complete the engine-
setup.
For now I still have not managed to get my nodes updatet, but the
engine is running at 3.6... The nodes seem to have another, not DB-
based, problem.

This line ^ is overwriting the complete OS configuration that you set
before, so the change to the boot device is lost. If you enable the
debug output of the SDK (with debug=True in the constructor of the API
object) you will see that this is what is sent:

  
your command line
  

Try this instead:

  vm.set_os(
params.OperatingSystem(
  boot=[
params.Boot(dev="network")
  ],
  cmdline=kernel_cmd
)
  )

It should result in sending this:

  

your command line
  

Not also that I believe that the kernel command line won't have any
effect for the PXE boot, as it is used only for direct kernel boot.

Take care that up to and including RHEL 7 mounting exports provided by the
localhost NFS-server can lead to deadlocks so it's not a recommended choice.
A loopback iSCSI target should be more reliable on this side.

Check /var/log/yum.log or use 'yum history' command and its sub

Do you have the list of the additional packages (or just the full list) you
got with your last yum install?

To get the transaction list:
   yum history list

To get detailed info on a specific transaction (# 44 in my example):
   yum history info  44

Can you please check and post here the details of your initial failed
transaction and the successful one?

Re: [ovirt-users] FW: Engine upgrade error

Any hints how to question yum or rpm? Maybe I just test-run yum
reinstall "ovirt-engine-setup*"  - It should then reinstall all
packages I hit with the former install, shouldn't it?

As Nir pointed out its possible.
I'm using such a setup at home where a NAS provides NFS storage for
hosted-engine and also iso/export/data domains for VMs. Besides that I
have an NFS server on my host for VMs which need a bit of disk
throughput, its got a nice SSD in it. Moving VM disks from the SSD
storage domain to the 'slow' storage domain on the NAS and vice versa
works fine.
Problem with these kind of setups is redundancy which is ofcourse
non-existant :-)

are you adding it later, when the VM is running? Is it a requirement to do it 
this way?
You can use oVirt vdsm hook[1] to inject custom snippet to libvirt’s xml on VM 
startup and add any channel you want. 
It would also allow you to pass arbitrary parameters from oVirt UI, should you 
ever need them.

When you attach a compute node to oVirt, it sets up auth with libvirt
to prevent admins from connecting to libvirt. If you want to oiverride
that you need to create yourself a SASL user + password using the
saslpasswd2 command eg see

http://libvirt.org/auth.html#ACL_server_username

how does the VM look like - what devices does it have (disks, graphics)?
does it boot in safe mode?
Is the OS type in Edit VM dialog set correctly?

Re: [ovirt-users] Failing to add NFS storage domain

[Jean-Pierre Ribeauville]

Hi,

Thx for your useful hint.

I'll go back to our sysadmin.

J.P.

Envoyé : mercredi 2 décembre 2015 15:41

Objet : RE: Failing to add NFS storage domain

Hi,

When looking inside the mounted NFS share, can you see if the needed folders 
are created (dom_md, etc.)?
We also had a same sort of error after trying to add a new NFS share to our 
development environment.

Adding the NFS storage would fail, but when looking at the host itself, the 
share would be connected.

In our case, we did see that the folders were created with permissions set as 
the root group, instead of the kvm group.
After changing permission settings on the NFS server, the share connected 
perfectly.

Kind regards,
Roel de Rooy

Onderwerp: [ovirt-users] Failing to add NFS storage domain


Hi,



By using 3.5 ovirt , I'm trying to add  an NFS  storage domain to my datacenter.





Then  I  got following error :


Error while executing action New NFS Storage Domain: Error creating a storage 
domain





I restart sanlock service on the host ( it's a RHEL 7)  ; no positive effect.



In engine.log  found this  :

Hi,

AFA IUnderstand , 
/var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qemu.guest_agent.0
  is a 
 channel used for QEMU agent , so no way to use it for private purpose.

Hi,

I wrote a C program running in a KVM host.
Part of it adds a Unix Channel device in all Guests in order to  have a dialog 
from Host to Guest.
As long as my host wasn't part of an Ovirt cluster , all was running fine.


I added my host in a ovirt cluster , and then , when running the script 
creating the channel device  ( by  using  "virsh attach-device  --persistent 
-live ." ) , I got following error :

Please enter your authentication name:
Please enter your password:
error: failed to connect to the hypervisor
error: no valid connection
error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): 
generic failure: All-whitespace username.)


What's the user/password I've to use then ?


BTW , I've seen that following channel device was  added to the Guest at its 
creation :

/var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qemu.guest_agent.0

What's used for ?
I presume I cannot use for my private purpose ?

I sent this topic to ovirt  and libvirt mailing lists , cos I don't know which 
forum is the right one for this kind of subject.


Thanks for help.

Let alone there is much less overhead if the machine specs is not that great 
and there are no other hosts available

Either way, importing KVM/libvirt VMs are currently a bit cumbersome (3.6 
supports v2v from VMware only), but doable with few workarounds, and it’s 
certainly safer than VMware or VirtuaBox

[ovirt-users] Migration from VirtualBox to oVirt (do's and don'ts)

[Kiril L]

As it seems a new server will have to be deployed soon. There is
almost no budget and i cannot afford more then one machine.

Because of that i was wondering if it would be possible to use
VirtualBox (for now) and later migrate to oVirt (when I manage to get
a permission)?

I was wondering is there something that i have to do (when setting up
the VM) in order to migrate at some point to oVirt?

Any particular reason you want to use virtual box? Why not do KVM with virt 
manager. That should be a painless conversion to oVirt since the format is the 
same.

the vm from one cluster to another I have the following messages:
Migration failed, No available hosts found

try switching to VNC, depending on v2v process that’s one thing which might go 
wrong easily.
If it doesn’t help you would need to get back to the v2v logs and see it there 
was any problem during the conversion, something unusual about your guest, some 
strange device, etc

no, it’s occupied by qemu-ga
even if you don’t start the guest process occupying it you would likely be 
interfering with libvirt’s internal functionality…..create your own and you can 
do whatever you want:)

Re: [ovirt-users] Migration from VirtualBox to oVirt (do's and don'ts)

[Diego Remolina]

To my knowledge there is no easy way to import VMs from virtualbox into
ovirt/RHEV. I asked RH support (with a contract) and they said it is not
supported.

The way I did it is very painful, so I can tell you it is possible.

1. Use clonezilla ISO and boot your virtualbox vm from that ISO. Use
clonezilla to create an image to a share (samba or nfs)

2. Create the new VM in ovirt/RHEV and the virtual drive. Boot from
clonezilla and restore the image to the new virtual drive.

I tested this on Linux guests. For windows guests you may need to somehow
add the ovirt drivers to the image under virtualbox prior to cloning it.

Re: [ovirt-users] Greetings and observations from an oVirt noob

[Ken Marsh]

Hi again,

Sorry for not getting back to you sooner.

I did read all that stuff, but what was totally unclear to me I finally 
understood from the Red Hat documentation. It's just the concept that an 
oVirt node's storage isn't used for VMs. I never would have guessed that 
in a million years.


Here's my situation - I have a bunch of Xeon workstations, each with 2TB 
HDD. I'd like to use them as both RHEV nodes AND use their HDD for 
storage. If I understand correctly, I can't do that. I'll need to set 
some up with RHEL 6.5 and share the storage, and I'll need to set others 
up as RHEV nodes to run the VMs. On the RHEL machines the CPU will go to 
waste and on the RHEV nodes the disk space goes to waste. Is this right?


The confusion I had about the hypervisor version is because when you are 
booting the 3.5 hypervisor, it says in the splash screen "oVirt 3.2.1". 
I'd much rather it said "Press F1 to see something useful," but now that 
I've figured this out I'm very happy with it.


I'm still learning and the more I learn the more I like. It's just so 
conceptually different from VMWare, and the doco and naming conventions 
seem to take the general concept for granted. Is the VM's disk really 
used over the network and not locally copied to the oVirt node where it 
runs? I guess in a purely datacenter environment that makes sense but I 
was hoping to make use of the storage on nodes too.


I think better I keep learning about it and when I understand 
completely, then I'll make suggestions on how to add/change the 
documentation. That would probably be more helpful, right?


Thanks again - amazing product. I'm enjoying this despite the initial 
confusion and trial-and-error learning.

Hello all,

I do development operations for a part of a software division of a large
multinational. I'm an experienced user of VMWare and Amazon AWS, soon to be
pushed onto Azure, and I've found a common thread among all solutions - they
are all expensive enough that my budget will certainly not be approved with
them. I'm deferred to the IT part of the organisation, which operates too
slowly and inefficiently (in terms of both cost and time) for my
requirements. This is what led me to RHEV, and ultimately to oVirt. This is
a feasibility study for what may ultimately be a RHEV-based data center in a
new office, and if I succeed we will be doing more on a fixed budget by
using more RHEV and less Azure.

I spent the weekend working with oVirt and I'm very impressed. I had no idea
such a comprehensive enterprise-class solution was even available. Being a
complete newcomer, I started without a clue and after a weekend had set up a
nearly-working data centre including an oVirt hypervisor node, all on old
Dell notebooks loaned to me temporarily by our IT group. I started with RHEV
but decided to use oVirt for two reasons - one being to see what's possible
with the latest and greatest, the other because RHEV required some licensing
I've not yet purchased. Long term it'll have to be RHEV for enterprise
support reasons I'm sure many are familiar with.

There are a few things I found, from a newcomer's perspective, very unclear.

What is oVirt, vs oVirt engine, vs oVirt node, vs oVirt host. Try to find
documentation on any of these and get spammed with references to the others.
I think I've worked out that these are the collective suite of products, the
management centre, the bare-metal hypervisor, and participating member
servers, respectively.

You got it mostly right.

Did you have a look at [1]?

The engine is the process that manages the whole thing. It exposes an admin
interface (web+api), monitors the hosts and VMs, etc.

A host and node are where VMs run. In many cases these terms are
interchangeable,
although usually "node" is a host installed with the ovirt-node image, whereas
an "ovirt host" is a host installed with a "normal" OS and later provisioned to
be used (by installing stuff on it, usually using the "New Host" wizard in the
web ui).

Which versions of CentOS/Fedora/oVirt Node are compatible at which oVirt
compatibility level? This would normally be addressed in the release notes.

I assume you refer to 3.6, released a few weeks ago.

The release notes page [2] does mention specific versions of fedora
and el. I agree
it could be written more clearly. The Download page [3] lists them too.

It was also confusing to discover oVirt node 3.2.1 is compatible at the 3.5

3.2.1? Where is this one referenced?

RN [2] has a section "ovirt node" with links to pre-release (has
ovirt-node-iso-3.6-0.999.201510221942) and final (still empty).

Our ovirt 3.5 host thinks it has an export domain, but it's not visible
anywhere, but it's keeping us from importing a domain from a different
datacenter.  What database update do I need to issue to clear the bad
state from the ovirt 3.5 we are trying to Import into?


Hi

Can you please provide the result of the following query

select * from storage_domain_static where storage_domain_type = 3;

Is that the storage domain you wish to remove ?


Correct.

Hi,

I wrote a C program running in a KVM host.
Part of it adds a Unix Channel device in all Guests in order to  have a dialog 
from Host to Guest.
As long as my host wasn't part of an Ovirt cluster , all was running fine.


I added my host in a ovirt cluster , and then , when running the script 
creating the channel device  ( by  using  "virsh attach-device  --persistent 
-live ." ) , I got following error :

Please enter your authentication name:
Please enter your password:
error: failed to connect to the hypervisor
error: no valid connection
error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): 
generic failure: All-whitespace username.)


What's the user/password I've to use then ?


BTW , I've seen that following channel device was  added to the Guest at its 
creation :

/var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qemu.guest_agent.0

What's used for ?
I presume I cannot use for my private purpose ?

I sent this topic to ovirt  and libvirt mailing lists , cos I don't know which 
forum is the right one for this kind of subject.


Thanks for help.

J.P. Ribeauville
