I have some ONE installations with differents FileSystems (XFS, EXT4) , Datastores (SAN (fslvm), NAS (Glusterfs, NFS), Networks (VLAN, isolateds), Hosts (Physical, Blades), HA for Sunstone…
My problem is when i must to evaluate the migration to other new ONE version.
I have think the possibility to virtualize my installation but with a backup the problem is that we dont have similar specs on the virtual environment so i couldnt evaluate the environment correctly.
Do you have any best practices to make a test environment based on a production cluster?
What is the best practices to clone an production opennebula to a for example virtualbox environment?
How do you make the test for brokens evolution from a production environment?
Thanks a lot!!
