- The models are 'native' if you like, definitely not workarounds. - CloudStack is an orchestrator, it largely relies on the abilities of the hypervisors that it orchestrates. We add a little secret sauce here and there, but when it comes to basic hypervisor functions, we leave it up to the hypervisor.

Do any of these models work "by default", or they are "workarounds" (similar to Proxmox / LXC)? Aka is this a native/direct solution that can be applied in the VM creation flow? > Yes CloudStack does support Xen Live Storage migration I was referring to something *similar* with Xen Live Storage migration, not Xen Live Storage "per se". Aka migrate a VM from a CloudStack node to another CloudStack node, natively, live, without using a central storage.
