Maybe it is a stupid question. But I have been thinking I've got several old computers, just lying around. would it be possible to pool together those computers in to a single "hardware pool" from which ubuntu server could pull it's resources from ? like say I wanted to setup several things like a few VM's and not care about which VM is running on what hardware, just setup a VM and the Servers themselves just figure out where to run that particular VM. is it possible with Ubuntu Server ?

I guess what I'm asking is One server OS, Several Computers as resources to be used ?

    Something like OpenStack can be used I guess. However, that is barely related to Ubuntu. Better ask at serverfault.com

    The scope of this question goes beyond Ubuntu as an OS. As pLumo mentions, OpenStack is one option. VM Clustering is another option (can be done with ProxMox). There is also Kubernetes and Docker Swarm. But these are all solutions that go beyond Ubuntu itself. Mar 15, 2022 at 13:53
  • so What I'm hearing is; there is no tightly connected Ubuntu server cluster.

  • I started looking into this one day and you might be interested in an ubuntu beowulf cluster. I've never done this but again, it might be something worth looking into.

  • While I agree to Openstack being the default thought here, there is also linuxcontainers.org/lxd/docs/master/clustering which nowadays can also do KVM based VMs and works better in a cli mode. In general less flexibility, but for that it usually "just works". Mar 18, 2022 at 15:14
