As on oVirt is it possible to attach local storage I supose it can be used
to run virtual machines:

I have drawn a couple of diagrams in order to know if is it possible to set
up this configuration:

1.- In on-going scenario:
Every host runs 100 vdi virtual machines whose disks are placed on local
storage. There is a common gluster volume shared between all nodes.

2.- If one node fails:

[image: Imágenes integradas 2]

oVirt has to be able to inventory the copy of machines (in our example
vdi201 ... vdi300) and start them on remaining nodes.

¿Is it possible to reach this configuration with oVirt? ¿or something

Making backup with the import-export procedure based on snapshot can take
lot of time and resources. Incremental rsync is cheaper in terms of

Thanks lot.
