Hi Razvan, - There are a few different models that you can use. But in short - 'yes' you can have a model where an IP is allocated to a VM and the VM keeps it. - No, we spend a lot of time making sure that upgrades between all versions work. Our versioning system requires that the API is backward compatible and we can only break that with a major version upgrade (say 4.x to 5.x )and that hasn't happened under Apache yet - Yes CloudStack does support Xen Live Storage migration - http://docs.cloudstack.apache.org/en/latest/adminguide/storage.html?highlight=live%20storage#storage-overview

Right off the bat here are the first questions: - in our current setup users can freely use each other's IP address, because the software stack doesn't enforce any limits (or requires us to manually edit stuff each time a VM is created). Does CloudStack have the same behavior? What we need is kinda simple: allow a specific VM to use a specific IP, and only that IP. - does CloudStack have the same "no-upgrade" policy as OpenStack? Ugrading OpenStack was/is nearly impossible, so I'm wondering if this is the case with CloudStack as well. - does CloudStack support "live-migration" between local storages? Xen does it, and does it really well. Again, I'm referring to local storage (local HDD/SSD/NVMe), not a central Ceph/Gluster/NFS store.
