Proxmox is an open-source bare metal virtualization system I use in my homelab – based on Debian and qemu, it supports a wide variety of hardware.
Proxmox VE version 7.3 has been released and the upgrade from 7.2 went without a hitch using apt. I’m looking into it now, there’s support for ZFS dRaid pools, an update to Ceph, and LXC looks to be updated to 5.0. I use LXC more than any of the clustering/storage tools, looking forward to seeing what’s new.
