[Users] Attach NFS storage to multiple datacenter

[Elad Ben Aharon]

In order to 'migrate' VMs between data centers, you can use an export domain.
You can create an export domain using the UI. You just have to specify 'Export / NFS' under: 'Domain Function / Storage Type'. Attach this export domain to the data center you would like to export the VM from.
Then, you'll be able to export your VMs to that domain (via 'Virtual Machines' tab on UI, click on 'Export').
When you finish migrating all the VMs from that data center, put the export domain in Maintenance, Detach it from the first DC and attach it to the second DC.
When the domain is active on the second DC, you'll be able to see your exported VMs on 'VM import' sub-tab under the export storage domain.
Import the VMs to the second DC.
Then you're done.

Subject: [Users] Attach NFS storage to multiple datacenter

Heho,
for some reason i currently have two active datacenters in ovirt 3.3
which should be cold migrated to one new datacenter.

Is there a simple way to attach an nfs-storage to all datacenters, so it
can be used to migrate the virtual machines? I was sadly unable to find
documentation on this issue online...

With best Regards,
Tobias
