Is there an API endpoint that VM's can query to discover it's oVirt
metadata? Something similar to AWS's http://169.254.169.254/latest/
meta-data/ query in EC2? I'm trying to stitch a lot of automation workflow
together and so far I have had great luck with oVirt. But the next small
hurdle is to figure out how all the post-install setup stuff can figure out
who the VM is so it can the appropriate configurations.
After upgrading cluster compatibility to 4.2 some VM won't start and I'm
unable to figured out why, it throws a java exception.
I've attached the engine log.
Thanks for any help/hint.

I have some problems adding VLANs to my VMs and I don't known if there is
a better way to do that, like a 'oVirt Way'.
All I need is to have a VM on "Test Network" that communicates with another
hardware/VMs on "Test Network". All VLANs are configured on my Switch, the
Hosts from oVirt are connected and tagged to this VLANs.
Is there a "oVirt Way" to do that other than "Setup Networks"? Can I use
with oVirt an Virtual Switch? Or a Network Stack?
I wrote this Bug about my Problem...
Thanks in Advance!

I haven't seen this hardware, but generally there are 2 possibilities:
1. Withing your SuperBlade management you need to specify unique IP address
for IPMI interface of each host
2. If 1. is not possible, but you have other identification of a host, then
you can try to pass that value using '-n' option on command line or
'plug=XXX' in Options field of a Fence Agent in webadmin

On oVirt 188.8.131.52, I'm trying to setup custom iptables rules as I'm doing
since years with engine-config --set IPTablesConfigSiteCustom="blah blah
On my hosts, I can see in my hosts that /etc/sysconfig/iptables does
contain the correct custom rules I added, but when manually checking
with iptables -L, I don't see my rules active.
On my hosts, I see that the iptables services is stopped and disabled,
and that the firewalld service is up and running.
That explains why iptables customization has no effect.
In the engine setup, I see that
/etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf contains :
I'm confused about this setting : when running engine-setup, I'm not
sure to understand if answering yes to the question about the firewall
will modify the engine, the hosts, or all of them?
Actually, I'd like my engine to stay with a disabled firewall, but my
hosts with an active one.
Is it true to say that this is not an option and I have to answer yes,
enable the firewall on the engine, allowing the
OVESETUP_CONFIG/firewallManager option to be set up (to firewalld or
iptables), thus allowing the spread of this setup towards the hosts?

Is there a way to make CORSFilter work for webadmin?
I have tried using the:
engine-config -l | grep CORS
engine-config -s CORSSupport=3Dtrue
engine-config -s CORSAllowedOrigins=3D*
service ovirt-engine restart
A look at:
engine-config -l | grep CORS
Looks like support is only for REST API?
- CORSSupport: "Enables CORS (Cross Origin Resource Sharing) support in
I have also tried adding to
But that just ends up in Server Errors https://pastebin.com/Q1JECzSw
Thanks for any help ;)

Hello Ovirt users,
Currently we haveing 4 Xen pools in our organization each pool have 8
Due to new 7.3 version change ,we plan to migrate our upcoming 5th pool to
Ovirt, the decision to do POC migration to Ovirt is from lots of Xen users
that suggested Ovirt migration better and mature product migrate to it.
I started to test Ovirt currently only with one server with engine
installed, my question regarding Ovirt sine i am really newbie with that
system , is , is it possible to have multiple engine on it ?
What happen if the engine server crash with some reason? can i load it on
another cluster server?
