community a solution I've come up with to easily backup multiple running 
oVirt VMs to OVA format using some basic Ansible playbooks. I've put 
together a blog post detailing the process which also includes links to 
a Github repo containing the playbooks here: 
https://blog.silverorange.com/backing-up-ovirt-vms-with-ansible-4c2fca8b3b43


Any feedback, suggestions or questions are welcome. I hope this

[ovirt-users] Re: Ovirt backup

[Torsten Stolpmann]

Well there is also https://github.com/vacosta94/VirtBKP (See 
http://blog.infratic.com/create-ovirtrhevs-vm-backup/) which is taking 
an image based approach which I assume might be faster.


Again, I have not tried it myself.

I personally prefer to have an easy to restore VM on the export storage 
to restore from, so I stick to the tools mentioned before.


But yes, the process takes a lot of space and time and your mileage may 
vary.

That's what VEPA Backup is also doing and is widely used in the Enterprise.
It depends of the type of storage you use. For example , file-based 
storage (NFS, Gluster) is easy - you can just copy the snapshot and then 
delete.


Yet , for block-based storage the only working solution I have seen to 
be working properly is the snapshot (VEPA backup) or it's clone to be 
presented to a VM for accessing it.
I don't know about this vProtect , but ssh cannot be faster than a tar 
over a tape or other media.


Of course, storage-based snapshots are the fastest , but they also 
require space.

The biggest problem with these tools is that they are very inefficient.  
To work they snapshot the VM then clone the snapshot into a new VM, back 
it up then delete.  This takes a lot of space and time.


vProtect and some other enterprise backup software snapshot the VM and 
stream the snapshot from the API without needing to clone or using a 
proxy VM.  The new version of vProtect even bypasses the API (because 
it's slow) and now supports streaming over SSH directly from the host.  
This is the ideal solution for oVirt VM backups imo, but I don't know if 
any free tool exists that can offer the same functionality.

To throw in my 2cents worth - I am totally happy with a mailing list and 
see absolutely no need for a change.


I heard that Google is very good at indexing btw. as is my mailreader.

you try to search for solutions, for some oVirt problems? It's a nightmare to go through 
this list here.

The comparison with Jira was probably wrong, although you don't have to use 
Jira like a ticketing system. I just wanted to express that I would like some 
kind of a modern tool. Something like StackOverflow maybe. Or a simple forum

[ovirt-users] Re: Intel Xeon X5460

[Torsten Stolpmann]

I might be wrong here, but I think that Conroe/Penryn processors are 
still supported if you set cluster compatibility version to 4.2.


On a personal side I also like to state that I am disappointed about 
this change as it artificially limits usage of older hardware. A warning 
about potential Spectre vulnerabilities in the UI would have been 
sufficient here IMHO.

If you use NFS, I would like to see your /etc/exports (after sanitizing

For extra bonus, output of "exportfs -v" would be useful.

In particular, I want to know if you use root_squash, all_squash, or 
no_root_squash.

You can give this a try, if you want:

It is very similar to oVirtBackup, but use the new API.

I am aware, that the release notes list API v3 as 'officially not

it still is available until 4.4 is released.


What is the situation here?

Done.



Thanks, removed.



I also added the restore.log containing the actual error which occured
during the restore.

Since this was a clean system I restored on, the setup has been executed
after the database restore, so the setup logs probably contain nothing
of interest. I added them anyway.


Sorry I wasn't clear enough. I meant the setup logs on the machine used
to create the backup. So that I can try to see why your backup contained
this function. Do you still have these by any chance?

Indeed, I can't see anything wrong in the logs above.


Sorry for misunderstanding, this totally makes sense.

I added the setup logs i found at:
http://www.klaros-testmanagement.com/files/ovirt/ovirt-setup-logs.tar.gz

Again, please let me know once I can remove them.


Done.


Thanks, removed.





Please let me know if there is anything I can add to this.


If you do not have setup logs from the original machine, at least try
to think about its history and tell us notable points - including entire
version history, setup/upgrade (or similar) problems you had there (and
perhaps worked around), etc.



We started with one of the first 4.0 releases and updated the system on
a regular basis since then. We almost never skipped a release.


The last log there is ovirt-engine-setup-20171231170651-lb3q89.log ,
meaning it was last upgraded almost a year ago. Were there indeed no
more upgrades since?



20171231170651 is most probably the date when we installed the last
major release (4.2.0). We did a lot more updates since and I now have a
suspicion what went wrong here.

We naively assumed that a yum update is sufficient for a minor upgrade
of the engine installation.


:-(


Rereading the documentation I think we were
missing explicit engine-setup calls after each minor upgrade.


Indeed



It may be the case, that the extra call to engine-setup is required to
not be part of the yum update.


engine-setup might need to ask the user questions, so we do not run it
inside yum update.

As long as it clear to users that this is required this is totally ok 
for me.



I think in this case it would be a good
idea to warn users that this step has not yet been taken and the update
is not completed yet.


Do you think you would have noticed? It's not that hard to add such a
message during yum update, but not sure it's that helpful.


Yes, I would probably have noticed that. Sooner or later ... :)


Perhaps we can also make the engine check e.g. if the setup package is
newer than itself, and warn the user in the admin ui.

I think that both is a good idea. Some applications even go the way to 
lock out users from the GUI until a necessary database migration has 
been executed by an administrator. Your mileage may vary here but this 
is the solution I would favor.




Could this be the cause for the missing logs and behavior discrepancies?

If yes, would another call to engine-setup in the current state fix this
and allow us to produce correct backups in the future?


If you still have the source machine, then yes, it should be enough.
Run engine-setup, then engine-backup again to backup, then restore
on the new machine.


Thanks, will do.




The log indicates the machine was upgraded to ovirt-engine-4.2.0.2 ,
which didn't remove the uuid functions. The bug I linked at before,
1515635, was fixed in 4.2.1.

Based on this, I think the best solution for now would be the patch
you suggested. Would you like to open a bug for this and push a patch
to gerrit? I can do this as well if you prefer. Bug summary line
should probably be something like:

engine-setup fails after restoring a backup taken with 4.2.0


I currently fear that would only cure the symptom.


Another solution would be to try using the same engine version during
restore (4.2.0.2), and only upgrade later. This is a bit hard, because
we do not have separate repos for each version, although they do
include all released versions - so you can try e.g.:

yum install ovirt-engine-4.2.0.2-1.el7

(meaning, after you remove existing 4.2.7, or you can try yum downgrade).

I didn't try this myself, not sure how well it would work. There might
be older dependencies to handle, and/or it might break due to too-new
stuff.


I don't think this is necessary.


Obviously, the best solution is to upgrade more often and backup more
often, and have a smaller difference between backup version and restore
version, ideally no difference. But I realize this does not always

If you do not have setup logs from the original machine, at least try
to think about its history and tell us notable points - including entire
version history, setup/upgrade (or similar) problems you had there (and
perhaps worked around), etc.



We started with one of the first 4.0 releases and updated the system on
a regular basis since then. We almost never skipped a release.


The last log there is ovirt-engine-setup-20171231170651-lb3q89.log ,
meaning it was last upgraded almost a year ago. Were there indeed no
more upgrades since?



20171231170651 is most probably the date when we installed the last 
major release (4.2.0). We did a lot more updates since and I now have a 
suspicion what went wrong here.


We naively assumed that a yum update is sufficient for a minor upgrade 
of the engine installation. Rereading the documentation I think we were 
missing explicit engine-setup calls after each minor upgrade.


It may be the case, that the extra call to engine-setup is required to 
not be part of the yum update. I think in this case it would be a good 
idea to warn users that this step has not yet been taken and the update 
is not completed yet.


Could this be the cause for the missing logs and behavior discrepancies?

If yes, would another call to engine-setup in the current state fix this 
and allow us to produce correct backups in the future?

There was indeed one glitch during updates which was connected to the
Postgres version in use:

The initial install was (accidentally) done under Postgres 9.4 which
happened to be present on the machine at that point of time. oVirt 4.0
was allowing this way back then. I think in 4.1 Postgres 9.2 has been
enforced, so there had been workarounds to allow updates under 9.4. This
got resolved with the migration to 4.2 which brought the Postgres 9.5
installation (if I recall that correctly).

Other than that I have no idea which might have introduced this.


All of this sounds irrelevant to current problem. Thanks for recalling :-)

Best regards,



If you find something in the logs you need more information on, please
let me know.

Torsten



If you, or anyone, manages to come up with a flow resulting in a 4.2
engine database that contains a function uuid_generate_v1 in the engine
database schema, I'd definitely want to know about it.

If you, or anyone, manages to come up with a flow resulting in a 4.2
engine database that contains a function uuid_generate_v1 in the engine
database schema, I'd definitely want to know about it.

Re-adding others posting in this thread, in case someone has a clue.
Perhaps one of you has setup logs of the machine on which the backup
was generated? If so, please share. Thanks.

That said, on a second thought, the implications of this are not that
significant - mainly somewhat lower performance - so perhaps it's more
important to fix your bug (by adding a line to IGNORED_ERRORS, as you
suggested)... but it's still weird.

Thanks and best regards,

More details:

This function should not normally be included in a 4.2 backup, and I do

If it's a clean 4.2 setup, it should never have been defined.
Earlier versions did create it, and the upgrade process should have
dropped it, if it's an upgraded setup. See also:

While I recommend looking at Ansible,

I found ovirt-shell an indispensable tool during troubleshooting when 
ssh is the last usable option, due to its interactive nature in relation

I feel sad to see it vanish in 4.3 without any equivalent replacement.

Will have a look at ovirtcmd though. Are there plans to make this

I've looked for it and I saw that ovirt-shell is already deprecated.


Correct.

We are using https://github.com/wefixit-AT/oVirtBackup for backups.

This works ok for us for nightly scheduled online backups of our vms 
managed by an oVirt 4.0.2.7 engine.


Is this the script you have been using?
