Based on my experience - the OVA contains the xml and the actual disk of the hosted engine.
Then the deployment starts locally the VM and populates the necessary data in it
Once it's over , the deployment shuts down and copies the disk of that local VM, undefines it and then ovirt's ha agents are being configured - so they can mount the shared storage and power up the VM (special tar /OVMF/ file on shared storage has the agent  configuration file).

So , in the ova there should be a  template VM + the xml config (cpus, ram, devices, etc) .
I would be surprised if there is something else in it.

Hi Strahil,

Yes, you are right.

After install ovirt-engine-appliance rpm, the ova file will be save at /usr/share/ovirt-engine-appliance/ovirt-engine-appliance-4.3-20190610.1.el7.ova

I was trying to understand what the ova file included.

I thought it only has the CentOS7.6.

I observed that ovirt-engine was installed during "host-engine --deploy"

Is ovirt-engine-appliance-4.3-20190610.1.el7.ova only used for deploy host-engine?

Is there a document about how to generate?


Thanks,

Jingjie

If I'm not wrong, this rpm is being downloaded to one of the hosts during self-hosted engine's deployment.
Why would you try to import a second self-hosted engine ?

Hi,
Can someone tell me how to generate  ovirt-engine-appliance ova file in ovirt-engine-appliance-4.3-20190610.1.el7.x86_64.rpm?
I tried to import ovirt-engine-appliance ova(ovirt-engine-appliance-4.3-20190610.1.el7.ova) from ovirt-engine, but I got error as following:
Failed to load VM configuration from OVA file: /var/tmp/ovirt-engine-appliance-4.2-20190121.1.el7.ova

I guess ovirt-engine-appliance-4.2-20190121.1.el7.ova has more than CentOS7.6.

Thanks,
Jingjie
