Hello Arik,

Interesting..

I was thinking that, by converting to OVA appliance, we can release our product as appliance that will work on Xen, VMWare or KVM. Now OVA works both on Xen and VMWare and both can be interchanged with each other.

Do you mean to say that both Xen and VMWare have written specific parsers to convert the disk formats amongst each other.

It's not just disk format - imagine the network interface driver - the PV Xen NIC driver vs. vmxnet3 (or however it's called) in VMware. Most of the HW devices are different as well.

Xen, I am talking about Citrix Xen.

Hello Arik,

Converting to an appliance (OVA) makes the VM portable. Works on multiple hypervisor. VM migration and interoperability becomes uncomplicated.

Thanks Anantha.

That's true only to some extent.

For example, without converting OVA that was generated by VMware using virt-v2v oVirt cannot consume it since the VMDK disks format is not supported in oVirt. Another example is the OVF representation that differs among various virtualization management platforms.

So if you are trying to migrate a VM from oVirt to another platform and assume you'll get this out-of-the-box by having an OVA that is generated by oVirt, I'm afraid you'll be disappointed in case the target platform doesn't support the format of the disks or doesn't know how to parse the OVF that is generated by oVirt.

And there may be more use cases for exporting the VM as OVA, that's why I'm interested to know what's the goal in this case :)

Hi Benjamin,

Unfortunately not.

We intend to make more use of the OVA format soon, we design this these days.

May I ask what is the motivation in your case to export the VM as OVA?

Regards,

Arik

Hi,

I'm using ovirt 4.0 and was wondering if it is possible to export an
existing VM to ova format (via the gui). If it's not possible via GUI,
is that possible at all?

Best Regards
Benjamin
