[ovirt-users] Move a VM between 2 setups

Hi,
The reason I use this term is because it is indeed 2 engines, or two different setups / environments.
I’m not talking about moving a VM from a virtual DC to another virtual DC in the same engine.
Best,

(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.

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.
