VirtualBox vs Proxmox Virtual Environment opinions
Use cases have practically no overlap. Proxmox requires dedicated server hardware and is of no use to casual users with desktops, whereas VirtualBox is controlled manually with a GUI and would be highly inconvenient and inefficient for the kind of infrastructure Proxmox is designed for
VirtualBox has different purpose
Virtual Box is mainly used to create desktop VM while Proxmox is to be installed on a server

Proxmox is a bare metal hypervisor with a good management interface. VirtualBox runs on an existing operating system. You can't replace one by the other as they have totally different use-cases.
They are not the same software at all... But I do understand the confusion, so here is a very very brief feature difference:
VirtualBox: Is a virtual machine (type-2 hypervisor) used to virtualize OSes/bootable software inside a host OS
Proxmox: Is a virtual environment used for (multi) server management which includes virtualization technology and hard drive redundancy through ZFS.
You can install it on top of an operating system and it just works.
Other solutions like proxmox require a lot of configuration and are difficult to maintain using apt because of dependency hell and messing with filesystem drivers like ZFS(it cause my ZFS filesystems to not boot, so i had to reinstall the whole server). I switchted to simpler virtualizations like VirtualBox.
Webmin is a web-based system configuration tool for Unix-like systems, although recent versions can also be installed and run on Windows. It allows to configure operating system internals, such as users, disk quotas, services or configuration files, as well as modify and control...
Webmin vs Proxmox Virtual Environment opinions
Webmin is a GUI for server administration. Proxmox is a virtualization environment.
OpenStack OpenStack is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. The project aims to deliver solutions for all types of clouds by being simple to implement...
OpenStack vs Proxmox Virtual Environment opinions
Openstack is for global companies, this solution is too expensive compare to Proxmox. Openstack is googd alternative to VMware vCloud Director for example.
XCP-ng is a high-performance, enterprise-level hypervisor with a rich ecosystem and is the result of massive cooperation between individuals and companies. All commercial features are enabled with no commitment required to a support agreement.
XCP-ng vs Proxmox Virtual Environment opinions
Works like Citrix hypervisor, and could be managed for free by XCP console for many platforms and you may adopt Xen Orchestra for automation and WEB management (freemium also). Both products came from same company so it works seamlessly.
oVirt is a virtualization management application. That means that you can use the oVirt management interface ( the oVirt engine) to manage hardware nodes, storage and network resources, and to deploy and monitor virtual machines running in your data center.
oVirt vs Proxmox Virtual Environment opinions
Fully featured, actively developed, good high availability featureset
bhyve (pronounced "bee hive", formerly written as BHyVe) is a type-2 hypervisor that runs FreeBSD 9+, OpenBSD, Linux and MS Window desktop (versions Vista, 7, 8/8.1/8.2 and 10), as well as MS Windows Server (versions 2008/2008R2, 2012/2012R2 and 2016 Technical Preview...
SmartOS is a hypervisor lean enough to run entirely in memory, powerful enough to run as much as you want to throw at it. Provisioning is blindingly fast, thanks to zones and ZFS file system creation.
(formerly XenServer) Citrix Hypervisor is a leading virtualization management platform optimized for application, desktop and server virtualization infrastructures.
Citrix Hypervisor vs Proxmox Virtual Environment opinions
It is a UI built on top of Webmin for managing virtual systems, such as Xen, KVM and OpenVZ instances. Using Cloudmin you can create, destroy, resize, startup, shutdown and restrict multiple instances using different virtualization technologies from a single interface.
