Can ISO Domain be shared across multiple data centers? Ovirt 3.5, 3.6? Does not appear so
Hello All, Tried setting up NFS ISO domain which works on one host/local datacenter. I do not want to have to have multiple copies of iso files on all hosts. If I try to import pre-existing ISO domain, I either get an error that storage path exists or the dialog just does nothing. Does not appear possible. Any tricks or workarounds?

Hi Liam, You should go to the Storage tab, select the domain and in the "Data Centers" subtab attach it to the second Data Center. let me know if that works for you. thanks, Liron.

Thanks Liron. When I try that, I select data center and click OK, the dialog closes, but nothing happens. No events generated, etc. On Sun, Nov 1, 2015 at 4:41 AM, Liron Aravot <laravot@redhat.com> wrote:

It's a hack, but it works.
This should work without any hacks. An ISO domain can be shared between multiple DCs or Engines. Tal?

When I try and create an iso domain with the same NFS path as another domain I get 'the selected storage path is not empty[...] Either remove the existing Storage Domain from this path, or change the storage path.'
