    Proxmox is an entire distro just for running virtual machines, with a web UI. Virt-manager is a program you install on a normal machine

        A bare metal OS is an OS running outside of a hypervisor. Virt-manager is a class 1 hypervisor that allows you to host guest operating systems. ( Run vms )

          Hey sorry for the confusion. What I meant is Proxmos is considered as a bare metal hypervisor and Virt manager is a hypervisor inside an OS, right?

            Technically no, both use kvm virtualization which is included in the Linux kernal, so both are “bare metal hypervisors” other wise know as class 1 hypervisors. Distinctions can be confusing 😂

              Oh dear… I really thought I understood what bare metal means… But looks like this is beyond my tech comprehension

                Bare metal is “kernel running on hardware” I think. KVM is a kernel feature, so the virtualization is done in kernel space (?) and on the hardware.

                  Well this can be a starting point of a rabbit hole. Time to spend hours reading stuff that I don’t really understand.

                    TL;DR: use what is in the kernel, without strange out of tree kernel modules like for VirtualBox, and use KVM, i.e. on fedora virt-manager qemu qemu-kvm

            *Proxmox

            Virtual manager is a application that connects to libvirtd in the back end. Think of it as a web browser or file manager for VMs.

            Proxmox VE is an entire OS built for virtualization on dedicated servers. It also has support for clusters and live VM migrations between hosts. It is in essence a server OS designed to run in a data center (or homelab) of some kind. If is sort of equivalent to vSphere but they charge you per CPU socket for enterprise support and stability

              Well this thread clearly established that I neither have technical knowledge and I don’t pay attention to spelling…

              Jokes aside this is a good explanation. I have seen admins using vSphere and it kind of makes sense. I’m just starting to scratch the surface of homelab, and now started out with a raspberry pie. My dream is a full fledged self sustaining homelab.

                If you ever want to get a Proxmox cluster go for 3-5 identical machines. I have a 3 totally different machines and it creates headaches

                  What kind of headaches are you having? I’ve been running two completely different machines in a cluster with a pi as a Qdevice to keep quorum and it’s been incredibly stable for years.

                    One device decided to be finicky and the biggest storage array is all on one system.

                    It really sucks you can’t do HA with BTRFS. It is more reliable than ZFS due to licensing

            They both use KVM in the end, so they are both Type 1 hypervisors.

            Loading the KVM kernel module turn your kernel into the bare metal hypervisor.

      It’s really just Debian with more packages preinstalled, but yeah, the idea is that you have an OS that has the primary purpose of virtualizing other machines.

        And a custom kernel with ZFS support

          Oh right, they ship a modified kernel, didn’t think of this. I also didn’t know about the zfs thing, my homelab uses btrfs.

            I’m also using btrfs, but I originally wanted ZFS before seeing that it was only available through FUSE on my distro.

            That’s why I even noticed ZFS was one of the features of Proxmox :)
