I haven two cluster setup, both on Ubuntu LTS and kvm. This has worked fine.
BUT. One cluster is a tiny two node compute with 1 Raspberry Pi running all storage and management. Storage is a bit slow, but a dedicated external usb with an SSD was quite a bit faster. It is a toy compared to what most people on this list run. The second is an experimental cluster at work, but it is still small compared to others. 1 management node 1 storage node for both primary and secondary 3 compute nodes They will be moved to a dedicated switch and converted to Rocky linux. When converted will likely pull a different version of kvm per previous discussions on this list. The short of it is the RedHat kvm rpm does not have all the features enable and some Cloudstack features wont work. If I remember correctly people used the epel kvm version with some success, including in production. I wrote some ansible roles to install both clusters, they are here with some example plays: [ https://gitlab.com/coledarr/cloudstack-roles | https://gitlab.com/coledarr/cloudstack-roles ] The roles, and example plays, will be updated as I finish the work on converting the work cluster to Rocky linux. But the work cluster is an experimental side project so it will be awhile before that happens. Darren -- This e-mail is confidential.

Therefore, since cloudstack 4.17.1.0 (will be released soon), Ubuntu 22.04 is officially supported by cloudstack. -Wei On Tue, 20 Sept 2022 at 19:16, Eric Green [ mailto:eric.lee.gr...@gmail.com | <eric.lee.gr...@gmail.com> ] wrote: BQ_BEGIN We have used both CentOS and Ubuntu. Currently we have standardized on Ubuntu 20.04 LTS due to Red Hat shenanigans with CentOS and for reliability reasons (Red Hat often broke Cloudstack with bug fixes for CentOS, Ubuntu has never done so). Once a version of Cloudstack is released that has been validated with Ubuntu 22.04 LTS and we have validated it ourselves we will upgrade to that. We currently have one old cluster running CentOS 7 (soon to be retired) and a new cluster running Ubuntu 20.04LTS. Both are operating in the same zone and pod without a problem, Cloudstack allocates virtual machines across both clusters without a problem.
