Re: [ovirt-users] Can't move/copy VM disks between Data Centers

Yes, thanks, this is exactly what I want to accomplish. BTW, are export domains from different data centers visible to each other? If not, wouldn't be simpler to export VM#1 in DC #1 to Export domain #1, copy over ssh to DC #2 Export domain, and finally import it into DC #2. PS. I can't test right now myself, sitting home on sick leave.. What you can do: - Add a shared storage domain to the DC#1 - Move VM disk from local SD to shared storage domain - Put shared storage domain to maintenance - Detach shared storage from DC1 - Attach shared storage to DC2 - Activate shared storage - You should be able to register the VM from the shared storage into the DC2 - If you want/need move disks from shared storage to local storage in DC2 Please test this flow with a dummy VM before doing on important VMs. Regards, Freddy On Mon, Feb 26, 2018 at 1:46 PM, Andrei Verovski <andreil1(a)starlett.lv&gt; wrote: > Hi, > > Thanks for clarification.
