G'day Leroy, OpenStack isn't a hypervisor itself, but more a collection of projects that can manage hypervisors and the compute workload that runs on them, among other things. If you have running hypervisors with workload already - as you mentioned, QEMU/KVM - migrating that workload to an OpenStack platform would require that platform to have hypervisors; which are generally also QEMU/KVM, although they do not have to be. To give you the right information, we'll want to understand better what it is you're trying to do: * It sounds like you have an existing workload on QEMU/KVM hypervisors. Why are you considering moving it? * What aspects of Openstack do you actually need? OS is a pretty big platform, and has a lot of features and benefits, but you pay for that with the overhead of having to manage the OpenStack platform. * You mentioned that you had looked at ProxMox (PVE) but were worried about it's requirement for centralised storage and fast networking; I can assure you that if you can run OpenStack, you're going to be more than capable of running PVE. Alternatively, if I have misunderstood your question, and you already have a running OpenStack, and you just want to know how to live-migrate a VM from one hypervisor host to another hypervisor host within the aggregate/availability zone? You can achieve this with a command like : openstack --os-compute-api-version 2.30 server migrate --live-migration --host {target-host-name} {instance-uuid} Give us a full write up - what have you got, what are you trying to do, what have you tried, why isn't it working? Maybe then we'll be able to help!

The current hypervisors are KVM/QEMU. Just looking at the documentation I am becoming overwhelmed. Questions (A URL which directly addresses the question is quite acceptable): Does OpenStack work with existing hypervisors or would existing hypervisors have to be "converted" (somehow) to OpenStack? If it can be used with existing hypervisors, is there a how-to for this specific task (I understand that OpenStack can do many things). If OpenStack can't be used with existing hypervisors, are you aware of solutions for this need? I have looked at ProxMox but it appears to want centralized storage and very fast networks which doesn't match the environment. Thank you for your help.
