[...] The case is when you want to spin up vms from a template, but use them only once and remove them afterwards (for example, running tests), if you had the option to have a shared storage where you store the templates, and then a local storage where you spin up the vms, that allows really fast (local) storage for the vms and avoids you having to setup a clustered storage (gluster, etc) for those vms that do not need any of those features.
So is that already possible? (For other threads and what I've tested seems not) Is that viable? Can it be implemented on ovirt?
Hi David, You could use a local replica-1 gluster storage domain for this. replica-1 => no split brains + local performance + no complexity + no overhead + gluster benefits It just works fine. PS: I'm currently researching the best way to live replicate local replica-1 volumes by using geo-replication, adding a replica-2 brick, using libvirt blockcopy or oVirt API.
