Thanks Christopher! That will force me to have as many gluster storages as hosts? Or it will allow to have one gluster setup with each of the hosts accessing to the local storage?
I will investigate, but I'd prefer if I did not have to use any external service at all (in the end, is just local storage) On 05/11, Christopher Pereira wrote: > On 08-05-2015 8:31, David Caro wrote: > >[...] > >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?
