Re: [ovirt-users] Q: Copying VMs between Export domains of different data centres

Hi Andrei,
I think you miss understand the concept of export domain.
Export domain allows you to pass entities from one data center to another.
The flow is:
1) Create an export domain in DC-A 2) Export required entities to the export domain 3) Deactivate (enter the storage domain to maintenance mode) and detach the export domain 4) Attach the export domain to DC-B and import the entities to it.
You can see more information here: - https://www.ovirt.org/documentation/admin-guide/chap-Storage/

Hi,

Copied exported from DC #1, exports -> 1d7208ce-d3a1-4406-9638-fe7051562994 -> images -> 12f48f07-7e93-4c66-b0e9-00efc1fec418, with 2 files inside fc469474-94fd-416b-b921-58604f46411c - 171 GB (seems like disk image) fc469474-94fd-416b-b921-58604f46411c.meta

However, in “Import Virtual machine(s)” dialog this VM is not visible even after running “Load” command inside import dialog. Looks like for whatever reason oVirt don’t refresh content of this directory.
How to instruct oVirt to refresh and index these files?
Or this method won’t work at all, and one have to import/export OVA images, or use lengthy procedure described by Fred Roland here ? http://lists.ovirt.org/pipermail/users/2018-February/087304.html
Thanks. Andrei
