[ovirt-users] Feature: enhanced OVA support

Tue May 16 14:56:41 UTC 2017

Great feature!  I am glad to see you plan to use the existing imageio
framework for transferring data.

Will you allow export of VMs from a particular snapshot?  I guess that's
how you'll have to do it if you want to support export of running VMs.

I think you should definitely have a comment in the ovf to indicate that an
OVA was generated by a oVirt.  People will try to use this new feature to
import random OVAs from who knows where.  I'd also recommend adding a
version to this comment:  or
perhaps even a schema version in case you need to deal with compatibility
issues in the future.

I agree with Yaniv Kaul that we should offer to sparsify the VM to optimize
it for export.  We should also return compressed data.  When exporting,
does it make sense to cache the stored OVA file in some sort of ephemeral
storage (host local is fine, storage domain may be better) in order to
allow the client to resume or restart an interrupted download without
having to start from scratch?
