VirtualBox...it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL). See "
About VirtualBox" for an introduction.
thanks,..
Shawn, you are kidding or it's a troll ? You are on a Proxmox forum here.
Proxmox ve is a professional virtualization solution developped under GPL license. It is aimed at a professional solution, as it has for example a bare metal installer, like VMWARE ESX. It has also many nice features, like clusterization, slick web interface management of the cluster, live migration (for KVM), snapshots (with LVM), backup with vzdump. Porxmox provides two virtualization solutions, both GPL : openvz and KVM. I use only KVM. As you perhaps know, KVM is included in mainline kernel, so it is available with every linux distribution. The fact that it is in the kernel insures that it will remain free GPL (at least till the linux kernel remains free, and I don't see a change in the license coming soon for kernel...)... This is one of the main reason why I chose KVM.
There are other GPL professional virtualization solution, like Xen (supported by many vendors).
In contrast, virtual box is aimed primarily as a desktop solution, even, as I read, some nice professional features have been added recently (live migration...). Only the free version is GPL, the full edition is closed (read your own links).
Morover, VirtualBox, which was bought by SUN, is now owned by Oracle. Do you know what happened to other open source projects from Oracle : OpenSolaris, OpenOffice and so on... ?
I'll certainly try virtualbox (at least on Windows), but in my opinion it remains a desktop solution.
Most of us here use Proxmox ve in a production environment. And we are waiting for version 2...
