Hi Christophe, An “export domain” is made for just this purpose. Create a NFS (version 3) share and make it accessible to the hypervisors for each engine. (It should be a dedicated NFS share, not used for anything else.) As I recall it should be owned by vdsm:vdsm (36:36). In one of the engines (doesn’t matter which), in the web admin page go to Storage and add a new NFS based export domain, using the NFS share you created. Once it’s activated, test it out; try right-clicking on a VM to “export” it.
Note that there can only be one engine connected to a given export domain at any one time. When you’re done testing the export domain on the first engine, you need to put it into “maintenance” and ultimately “detach” it. Then go to the other engine, and this time under Storage instead of “new domain” click “import domain” and enter the same NFS share information. It should recognize that you already have an export domain setup under that NFS share. Attach and activate it, and under Storage / <your export domain name> / VM Import, try importing the VM you had previously exported. This is covered (sparsely) in the oVirt documentation at https://www.ovirt.org/documentation/admin-guide/administration-guide/, and it’s covered more coherently in the commercial RHV documentation at https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/single/administration-guide#Storage_properties.

With 2 engines, we then want to be able to move VMs (one time) from current engine where they are running to new engine in the other building. Is there a recommended workflow for doing this? We have access to shared NFS for this task if required. Thanks for any pointers, Christophe -- Dr Christophe Trefois, Dipl.-Ing.
