[ovirt-users] Re: Error with LDAP

[Lucie Leistnerova]

Hi Lucas,

how is your ldap set? Can you please share settings in 
/etc/ovirt-engine/extensions.d

Is the driver properly set? I've found similar issue here
https://users.ovirt.narkive.com/FveKIVCV/ovirt-users-adding-users-through-ldap-fails-on-external-id

Thank you.

Hello everyone.

I have previously configured LDAP connexion though 
ovirt-engine-extension-aaa-ldap-setup.

The only working configuration was IBM Security Directory Server (the IBM 
Security Directory Server RFC-2307 Schema doesn't work), ladps and anonymous 
search user. But the LDAP server I’m testing is OpenLDAP and not IBM.

Indeed with IBM  the search and login are working fine when I test them with 
ovirt-engine-extensions-tool aaa.

But when I try to add a LDAP User in the User Administration Panel I get this Error 
message : "Error while executing action AddUser : Internal Engine Error".

None of the solutions I've found on previous threads seems to works.

Does someone have an idea please ?
Please find the logs attached.
Thank you beforehand.

[ovirt-users] populating the ISO domain

[eevans]

This may be common knowledge so if it is redundant, apologies.
My ISO domain did not populate automatically but with some research I found out 
how to utilize it and populate it.
If you have it in place with the correct permissions and security, you can 
manually populate it using the api.
From the engine host at the command prompt:
# ovirt-iso-uploader list
This gives you the name of your iso domain. If it prompts for a passwd, it 
should the the same as the admin@internal login.
The to upload files and populate it:
ovirt-iso-uploader -i ISO upload *.iso or *vfd for floppy images

I hope this helps.

[ovirt-users] DR different number of Host

[ernestclydeachua]

Hello,
Currently i have a standalone ovirt on a primary site and planning to create a 
DR
but my DR lacks a baremetal that has a same resources on primary site.

is it possible on DR to have multiple hyper-visors then automatically assign 
where the vm should run/attach automatically?

[ovirt-users] Re: paused vm's will not resume

[eevans]

I had several vm's pause again. The message in the event log is:
VDSM command SetVolumeDescriptionVDS failed: Volume does not exist: 
(u'e3f79840-8355-45b0-ad2b-440c877be637',)
I restarted nfs on that node and clicked run  and they all resumed. 
This is local storage on the node with over 200GB of free space but they were 
paused due to a storage error.
Do you still want the xml files? It seems ovirt is losing contact with the 
export.

Can you share the VM XML of these VMs?

The easier way is:

# virsh -r list

# virsh -r dumpxml vm-id

Also having vdsm.log from the time the vm was paused would help to understand 
why the vm was paused.

For block storage, paused vms are expected to be resumed once the vm disk is 
extended, or if the vm paused because storage was not accessible temporarily, 
once the storage becomes accessible again.

For file based storage, we don't support yet resuming paused vms.

[ovirt-users] Re: hosted-engine --deploy --restore-from-file fails with error "Domain format is different from master storage domain format"

[djagoo]

After three weeks the only possible solution I can see is

- undeploying hosted engine from one of the hosts
- removing the host from the cluster
- creating a new DC
- creating a new Cluster
- recreate all networks etc. from the old DC in the new one
- add the host 
- add a new temporary V5 SD serving as MasterSD
- backup of the hosted-engine
- enable global ha maintenance
- shutdown of the hosted-engine
- hosted-engine --deploy --restore-from-file using the new datacenter and 
cluster on the one host in the new DC
- unattach V4 storage vom old DC reattach to the new DC and hope that all vm's 
are showing up on the new DC
- adding the remaining 2 hosts to the new DC and reinstall/redeploy 
hosted-engine to them

Do you think this could be the solution? Is it possible to move everything from 
the old DC to the new one by attaching the storage to it or am I loosing 
information about the vms (assigned MAC Addresses and so on)?

Regards

Marcel

Hi Eric,


In order to use virsh , set the following alias:
alias virsh='virsh -c

This is why I use the -r flag.

$ man virsh
...
   · -r, --readonly

   Make the initial connection read-only, as if by the --readonly
option of the connect command.

becomes accessible again.

For file based storage, we don't support yet resuming paused vms.

[ovirt-users] Re: paused vm's will not resume

[Darrell Budic]

What version of ovirt are you running? What is your storage domain, nfs or 
gluster? Using libglfapi? How full is your storage domain? If it’s gluster, 
what type is it and how full are all the bricks?

Have you tried stopping and restarting them? Not ideal, but may get you a 
running system again. 

Are there other VMs which continue running without trouble? If so, do these two 
do heavy disk IO?

good luck,

  -Darrell

[ovirt-users] Error with LDAP

[Lucas Lamy]

Hello everyone.

I have previously configured LDAP connexion though 
ovirt-engine-extension-aaa-ldap-setup. 

The only working configuration was IBM Security Directory Server (the IBM 
Security Directory Server RFC-2307 Schema doesn't work), ladps and anonymous 
search user. But the LDAP server I’m testing is OpenLDAP and not IBM.

Indeed with IBM  the search and login are working fine when I test them with 
ovirt-engine-extensions-tool aaa. 

But when I try to add a LDAP User in the User Administration Panel I get this 
Error message : "Error while executing action AddUser : Internal Engine Error".

None of the solutions I've found on previous threads seems to works.  

Does someone have an idea please ?  
Please find the logs attached.
Thank you beforehand.

[ovirt-users] Re: What is this error message from?

[Jeremy Tourville]

I don't recall running any convert operations on the host and certainly not on 
the time/date listed.  *If* I ran any conversions were run, they were run from 
a laptop and then I moved the converted disk to this host.  I definitely didn't 
make any volume changes.  Is this image conversion part of the template 
process?  I have been creating quite a few templates lately.  I have noted that 
several of them failed and I had to rerun the process.  Is this some sort of 
process that just keeps trying over and over because it thinks it failed?  
That's the only theory I can come up with.

This is a weird one. Not only that reading shouldn't be looking up any
filename, but also that it's not at offset 0, but suddenly somewhere in
the middle of the image file.

I think it's pretty safe to say that this error doesn't come from QEMU,
but from the kernel. Did you (or some software) change anything about
the volume in the background while the convert operation was running?

This may be an error from template creation.

We don't have such jobs.

You may grep for this task id in all logs and share the matching logs.

Note that you have binary data in your logs, so you need to use "grep -a".

That's the only theory I can come up with.

[ovirt-users] Re: I wrote an article on using Ansible to backup oVirt VMs

[Jayme]

Gianluca,

Thank you so much for the great feedback, it is very much appreciated! I
too have to carve out some time to test some of these ideas more
thoroughly, but I wanted to offer some of my initial thoughts anyway.

My goal is for the playbook(s) to be as simple as possible with as little
configuration as possible. Ideally I'd love to see the playbooks able to be
run from any host without requiring a connection to the engine database or
needing to have access to storage in order to verify export status.

1. Vault: I am aware of this and have seen this method used in other
oVirt/RHEV documentation. The reason I left it out is because I want to run
the playbook on cron without being prompted for a password. This could
potentially be solved by specifying the vault password as an environment
variable in cron, but in the end the password still needs to be provided
somewhere for the playbook to work hands-off. I suppose it's a matter of
which is the most secure and recommended way to do so.  Open to suggestions
here.

2. Blocks: I am aware of the use of blocks in Ansible but don't personally
have much direct experience using them. Your idea to use a block for SSO
token seems reasonable and likely should be implemented. I need to test
that out.

3. Export Timing: I like your solution for probing the DB for export status
and I'd like to spend some more time looking at that. I wonder if it's
perhaps a bit too complex and if there may be an easier way without
directly interacting with the engine database. One idea I had which I think
could work would be by use of the
https://docs.ansible.com/ansible/latest/modules/ovirt_event_info_module.html#ovirt-event-info-module
module.
I believe this module could be used in a wait_for until the message "Vm X
was exported successfully as a Virtual Appliance to path..." appears in the
VM's event messages. To make sure we don't get prior events we could
register the current event index ID in a variable then use the "from_"
parameter to only search for new events. I do think something like this
could work but I haven't had enough time to thoroughly test it and I'm not
sure if it's the best possible solution. There may be an even easier way to
determine the export status using existing ovirt Ansible modules but I have
not found one yet. What are you thoughts on this method?

I'd also be interested to hear if you have any thoughts or opinions on ways
to improve backup retention policy to make it more versatile.

Thanks again for your feedback!

- Jayme

[ovirt-users] Re: HostedEngine migration fails with VM destroyed during the startup.

[Vrgotic, Marko]

Hey Strahil,

I am not in a rush to patch the Node3 as much as I want to exit global 
maintenance, assuming all goes well, to allow my Users to use platform for 
their work further. 

As far as I am concerned, Node3 patching can wait. I like that kind of 
paranoia, and would actually call it "better safe than sorry".

At 18:00 today should be approximately 8-10 hours since I started Engine via 
virsh, so I will than try to continue with bring it back online via VDSM onto 
one of the Updated nodes.

Will send the update once last portion is done.

Thank you.

Hi Shani,

that didn't work. I edited the cluster, re-chose 4.3 and saved it, and then 
edited the DC, re-chose 4.3 and saved it. The SDs are still on V4 and V5 is not 
attachable.

[ovirt-users] Re: Move Self Hosted Engine to Standalone

[Jeremy Tourville]

OK, that worked perfectly, thanks!  I was able to run the restore and then run 
engine-setup.  How do I remove the old self-hosted engine  properly?

Hi Jeremy,
   I think you must have run the engine-setup before the 
restore, the restore is designed to restore to a clean install or the previous 
install with the same credentials. If you delete the postgresql config you can 
then install with your postgres credentials.

e.g.
systemctl stop rh-postgresql10-postgresql.service
rm -rf /var/opt/rh/rh-postgresql10/lib/pgsql/data/*

Paul S.

I did get a little further.

First I ran engine-cleanup on my new engine where I will be running the restore 
operation. (I had previously run the engine-setup script on this machine)

Then I ran this-

[root@engine ~]# engine-backup --mode=restore 
--file=ovirt-engine-backup-20200217125040.backup 
--log=ovirt-engine-backup-20200217125040.log --provision-db --provision-dwh-db 
--restore-permissions
Start of engine-backup with mode 'restore'
scope: all
archive file: ovirt-engine-backup-20200217125040.backup
log file: ovirt-engine-backup-20200217125040.log
Preparing to restore:
- Unpacking file 'ovirt-engine-backup-20200217125040.backup'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
FATAL: Existing database 'engine' or user 'engine' found and temporary ones 
created - Please clean up everything and try again

Time to research further for that FATAL error message.  Isn't that the purpose 
of engine-cleanup though?  Why the conflict?

Try looking at the RHEV info here and go to section 6.2.2 and see if that helps.

OK, I was able to get the backup completed.  I am a little confused on how to 
do the restore though.  
https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment.html

Is this link even applicable?  My environment is a single node, not EL based.  
Anyhow, here is what I have so far-

[root@engine glusterfs]# engine-backup
Start of engine-backup with mode 'backup'
scope: all
archive file: 
/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup

Packing into file

Notifying engine
Done.
[root@engine glusterfs]#

I moved the backup file to my new engine.
How do I perform the restore?

The directions say:

# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --provision-dwh-db --restore-permissions

What is the file name and log_file name?  Do I need to do something to unpack

Hi Jayme,
sorry in advance for the long mail, where I try to give details; I don't
know your Ansible experience.
A very nice and clean article indeed, with useful details (apart from text
not justified: I prefer it but YMMV) and pretty fair with vProtect work and
also pros and cons of their solution.
I met Pawel Maczka from vProtect during oVirt Summit last year and I was
able to appreciate his kindness and skill and efforts in integrating with
oVirt/RHV.

That said, I have some suggestions for you. In the next days I could work
on a similar need for a customer, so it will be nice to share efforts and
hopefully results... ;-)
This week I have not much time but if you can elaborate and test what
below, we can share.

1) engine parameters
you could use ansible vault to encrypt credential files, to have better
security and so you can disclose the playbook files without having to care
abut sensitive information
In my case I put username, password, ovirt mgr fqdn, ovirt ca file all in a
file and then encrypt it (and also engine database ones, see below).
Then I create a securely protected vault file named "vault_file" where I
store the vault password and then I recall the playbook with:

ansible-playbook  --vault-password-file=vault_file backup_ovirt_vms.yml

Alternatively you are prompted for the vault password each time you run the
playbook

2) The best practice of using the oVirt SSO token in Ansible is to use a
block of kind:

  tasks:

- name: Ansible block to export as OVA
  block:

- name: Obtain SSO token using username/password credentials
  ovirt_auth:
url: https://{{ url_name }}/ovirt-engine/api
username: "{{ ovirt_username }}"
password: "{{ ovirt_password }}"
ca_file: "{{ ovirt_ca }}"

- name: "Backup VMs"
  include_tasks: export_vm.yml
  loop: "{{ vms }}"

  always:

- name: Revoke SSO token
  ovirt_auth:
state: absent
ovirt_auth: "{{ ovirt_auth }}"

So that anyway, thanks to the "always" section, you are sure to revoke the
token

3) To manage timing of export to ova that fires up and suddenly completes
from an ansible job point of view.
Possibly overkill, I don't know if ovirt_job module in any way could do the
same, but I try to solve using the engine db

Please note that engine db credentials are on engine inside file:
/etc/ovirt-engine/engine.conf.d/10-setup-database.conf

and by default you can connect remotely to the database with engine user
and with password being encrypted over the network thanks to pg_hba.conf in
directory
/var/opt/rh/rh-postgresql10/lib/pgsql/data/pg_hba.conf

# TYPE  DATABASEUSERADDRESS METHOD
hostengine  engine  0.0.0.0/0   md5

There are two tables involved
"job_subject_entity" table that you query and where entity_id should be the
id of the VM you are exportng and from this table you get the related job_id
"job" table where you query for the job_id matching from what you got from
previous query (eventually to refine if you have more concurrent jobs
running against your VM and you have to filter what interests to you, eg
action_type= ExportVmToOva ... TBD)

Eg:
export running

engine=> \x
Expanded display is on.

engine=> select * from job_subject_entity where
entity_id='442a1321-e366-4ea2-81bc-cad6e860a517';

[ovirt-users] Re: hosted-engine --deploy --restore-from-file fails with error "Domain format is different from master storage domain format"

[Shani Leviim]

Hi Marcel,
Before ovirt-engine-4.3.3.2, the 4.3 compatibility version was considered
as V4, and from that version, it was considered as V5.
Therefore, it seems that since your Default DC was created before that
version, it was considered as V4.

You can try to make it V5 by doing the following:
- Edit the Default cluster, re-choose the 4.3 option on the 'Compatibility
Version' field and press OK.
- Do the same for the Default Data Center.

I believe that your newer engine, which considers 4.3 as V5 format, will do
the relevant update on your environment.


*Regards,*

*Shani Leviim*

[ovirt-users] Re: Move Self Hosted Engine to Standalone

[Staniforth, Paul]

Hi Jeremy,
   I think you must have run the engine-setup before the 
restore, the restore is designed to restore to a clean install or the previous 
install with the same credentials. If you delete the postgresql config you can 
then install with your postgres credentials.

e.g.
systemctl stop rh-postgresql10-postgresql.service
rm -rf /var/opt/rh/rh-postgresql10/lib/pgsql/data/*

regards,
Paul S.

I did get a little further.

First I ran engine-cleanup on my new engine where I will be running the restore 
operation. (I had previously run the engine-setup script on this machine)

Then I ran this-

[root@engine ~]# engine-backup --mode=restore 
--file=ovirt-engine-backup-20200217125040.backup 
--log=ovirt-engine-backup-20200217125040.log --provision-db --provision-dwh-db 
--restore-permissions
Start of engine-backup with mode 'restore'
scope: all
archive file: ovirt-engine-backup-20200217125040.backup
log file: ovirt-engine-backup-20200217125040.log
Preparing to restore:
- Unpacking file 'ovirt-engine-backup-20200217125040.backup'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
FATAL: Existing database 'engine' or user 'engine' found and temporary ones 
created - Please clean up everything and try again

Time to research further for that FATAL error message.  Isn't that the purpose 
of engine-cleanup though?  Why the conflict?

Try looking at the RHEV info here and go to section 6.2.2 and see if that helps.

OK, I was able to get the backup completed.  I am a little confused on how to 
do the restore though.  
https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restoring_an_EL-Based_Self-Hosted_Environment.html

Is this link even applicable?  My environment is a single node, not EL based.  
Anyhow, here is what I have so far-

[root@engine glusterfs]# engine-backup
Start of engine-backup with mode 'backup'
scope: all
archive file: 
/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup
log file: /var/log/ovirt-engine-backup/ovirt-engine-backup-20200217125040.log
Backing up:
Notifying engine
- Files
- Engine database 'engine'
- DWH database 'ovirt_engine_history'
Packing into file 
'/var/lib/ovirt-engine-backup/ovirt-engine-backup-20200217125040.backup'
Notifying engine
Done.
[root@engine glusterfs]#

I moved the backup file to my new engine.
How do I perform the restore?

The directions say:

# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --provision-dwh-db --restore-permissions

What is the file name and log_file name?  Do I need to do something to unpack 
my backup file?

Can you take a backup  of the original, build the new one, then do a restore?

This is a weird one. Not only that reading shouldn't be looking up any
filename, but also that it's not at offset 0, but suddenly somewhere in
the middle of the image file.

I think it's pretty safe to say that this error doesn't come from QEMU,
but from the kernel. Did you (or some software) change anything about
the volume in the background while the convert operation was running?
