I still don't get why you need the OVA .
Are you trying to extract and put it into another virtualization. If this is your intention - better install it as if it was a standalone engine. 

Yes, I am trying to build ova with different OS.

What do you mean install it as standalone engine?

install VM first then install as ovirt engine?


Thanks,

Hi Strahil,

Thanks for your reply.

Can you share the procedure of creating ovirt-engine-appliance ova?


Thanks,

Jingjie

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
