They are similar, but Qubes is more targetted at the end user - proxmox is more traditionally used as the hypervisor for distributed applications. You can probably achieve the same goals with either though (barring differences in Xen and KVM).

Proxmox isn't a hypervisor (last time I checked!), it's a management plane to different hypervisors.

  > Proxmox is an open-source, Type 1 hypervisor that comes as a Debian-based Linux distribution. With Proxmox, users can experience a hypervisor that can integrate Linux containers (LXC) and KVM hypervisor, networking functionality, and software-defined storage in a unified platform. I'm not saying you are wrong entirely - it can be used as a management plane for different hypervisors, but it is also a hypervisor in it's own right as I understand it. (grabbed the quote above from ServerWatch). There is a lot of confusion about this topic as some people argue it isn't a type 1 because it goes through KVM, but others rebut that because KVM is in the kernel and has direct hardware access (very gross summary of arguments I barely know enough about to keep up, and sometimes don't).

  > Proxmox isn't a hypervisor KVM is in the kernel, and I specifically called out KVM. If the point you are trying to make is that KVM is the hypervisor, then Qubes is also not a hypervisor because it uses Xen. But this seems like a very strange distinction to make to me unless you are specifically trying to peer into the inner-workings. At that point you'd probably be saying ESXi is "not a hypervisor" because it has to defer the actual VM deployment to vmkernel. I don't know of an OS without a kernel.

    Proxmox can use a hypervisor, KVM, or manage containers. It's not a hypervisor. Xen is also hypervisor. Saying proxmox is a hypervisor is like saying virt-manager is a hypervisor.

      You're just debating semantics, debatably incorreectly, and for no reason. KVM is not a type-2 hypervisor in this case - Proxmox can be hosted on bare metal and use KVM natively. > Saying proxmox is a hypervisor is like saying virt-manager is a hypervisor. This is... just wrong? Proxmox is much more equivalent to ESXi than to a UI application. -- To grante you the tiniest bit of good faith, I would wager that you and I are two heads of this specific coin. An excerpt from Wikipedia on the matter (https://en.wikipedia.org/wiki/Hypervisor https://en.wikipedia.org/wiki/Hypervisor): > The distinction between these two types is not always clear. For instance, KVM and bhyve are kernel modules[6] that effectively convert the host operating system to a type-1 hypervisor.[7] At the same time, since Linux distributions and FreeBSD are still general-purpose operating systems, with applications competing with each other for VM resources, KVM and bhyve can also be categorized as type-2 hypervisors.[8] You seem very concerned that KVM (and thus Proxmox) cannot be considered a Type 1 Hypervisor. I disagree. But if your assertion is that Proxmox cannot natively deploy VMs... then I have no idea what to tell you. You're blatantly wrong. Just try it.

        Just try it? Didn't want to have a pissing contest, but if you will. I've have, since late 2000's and used it to deploy production deployments for eden.sahanafoundation.org in Haiti, Chengdu and other places, using Proxmox and KVM. I've also built public and private clouds using OpenNebula and OpenStack (using KVM/libvirt). I'm also vmware certified (or was, back in late 2000's, when working for a prominent UK ISP). It's a management framework, it doesn't do virtualisation itself, it uses the libvirt framework. I can use the same kvm hypervisor by using qemu-kvm (or virt-manager, which uses the same stuff). Again it's just a management layer.
