[ovirt-users] Re: Actual oVirt install questions

Thank you.
I read through the "ovirt-imageio: can't upload / download" thread, and your 
brief glossary was very helpful. Perhaps it would make sense to put some basic 
terminology like that somewhere in the official oVirt docs? I feel like there 
are a million different ways to install and configure oVirt, and it has taken 
me quite a bit of time to figure out the differences.

I took your advice, and figured out how to get the "standalone engine" 
installed and running. I'm now able to log into the oVirt Admin Portal, view / 
create Datacenters, etc..

At the risk of creating a redundant thread, I'm going to reply to this thread 
about a problem I'm having uploading ISOs through the Admin Portal. I can't do 
it! Perhaps my issue is related to the same issue Michael is facing in the 
thread I just referenced - ovirt-imageio: can't upload/download.

I have the standalone install:

[dwhite@dev1-centos ~]$ sudo yum info ovirt-engine | grep Version
Version  : 4.4.1.10
[dwhite@dev1-centos ~]$ sudo systemctl status ovirt-imageio
● ovirt-imageio.service - oVirt ImageIO Daemon

vendor preset: disabled)

ImageIO Daemon...
Aug 21 19:16:28 dev1-centos.office.barredowlweb.com systemd[1]: Started oVirt 
ImageIO Daemon.

This is of course a new, default install.

I have created a data directory for VM images, as well as ISOs:
[dwhite@dev1-centos ~]$ ls -la /data/
total 0
drwxr-xr-x.  4 vdsm kvm   31 Aug 19 20:49 .
dr-xr-xr-x. 19 root root 260 Aug 19 20:28 ..
drwxr-xr-x.  3 vdsm kvm   50 Aug 21 20:12 images
drwxr-xr-x.  3 vdsm kvm   50 Aug 21 20:12 iso

I am now trying to upload an ISO through the Admin Portal by going to Storage 
-> Disks -> Upload -> Start.

My client machine is Ubuntu.

I click "Test Connection" and I get the error message:
Connection to ovirt-imageio-proxy service has failed. Make sure the service is 
installed, configured, and ovirt-engine certificate is registered as a valid CA 
in the browser.

I downloaded the certificate by clicking on the link provided, and saved it 
into /usr/share/ca-certificates/mozilla/
I then ran: sudo update-ca-certificates

Then I reloaded the oVirt admin portal.
I'm still getting the error message.

Any advice here?
Or am I running into the same problem that Michael has run into?

[ovirt-users] Re: oVirt SHE smart-automated backup

[Vrgotic, Marko]

Hi Strahil,

That's true. I do trust migration mechanism, its proven to work smoothly 
many-many times, but I do not like moving SHE VM unless I have too.
Proper backup is important and I try to follow oVirt recommendation, but if I 
can avoid needless "shaking" of the platform, I would rather take that route.

Actually,
you don't need  to find where the SHE is.
Once you setup the host in maintenance, all VMs including the SHE will be 
evacuated out of there.

[ovirt-users] Re: Incremental VM backups

[Paweł Mączka]

Kevin,

Feel free to play with vProtect. Incremental works for 4 different strategies 

And yes - 10vms are for free.

Details you can found in below doc.

Vprotect can do some form of incremental backup of ovirt vms. At least on 4.3

Hi

I am looking at ways to backup VM's, ideally that support incremental backups. 
I have found a couple of python scripts that snapshot a VM and back it up but 
not incremental. The question is what do you use to backup the VM's ? (both 
linux and windows)



Thanks

Kevin

[ovirt-users] Re: Max running ansible-playbook

[Tommaso - Shellrent via Users]

Hi. No, we use a simple python script that trigger one single export.

We have a lot of single server datacenters with local storage, and in 
all of them we run this scrip almost simultaneously.

No one have this kind of problem?

We use OVA export to make some backup, but the whole task takes a
lot of time because only one ansible-playbook
"/usr/share/ovirt-engine/playbooks/ovirt-ova-export.yml" run at
the same time.


How do you trigger the export operations?
Do you select multiple VMs/templates in the webadmin and call export 
to OVA?

Hi to all.

on our angine we always see max 1 ansible-playbook running on the

How can we ingrease this value?
