Our company offers virtual private servers based on VDSmanager (FreeBSD) and OpenVZ (Linux) virtualization technology. The following article gives a detailed comparison of these two technologies for VPS hosting.

Disk space

VDSmanager contains FileSystem (vdsfs) providing user files (private disc) and disk templates within the file system. On the user level the file system content is displayed in a single block. This technology provides a wide range of pre-installed software that doesn't use server memory. Besides, a user doesn't need to care about updating, as it is provided by the developers. There are also templates without pre-installed software but the operating system, occupying about 350 Mb of the disk space.

OpenVZ does not distinguish between user or template files. When creating VPS, all files are copied to the user's directory and occupy disk quota - virtual server disk space. Thus, updating is not available, and virtual server administrator should do it by himself, for example, update the software in case of any bugs or problems.


VDSmanager displays resource memory being used by any application in real-time. Virtual servers based on the virtualization technology enables to economize RAM, as the applications use the required amount of allocated memory providing stability of servers even with low memory capacity.

In OpenVZ RAM is considered to be used, if it was requested by any application. That's why virtual servers require much resources and are less stable when the resources are not sufficient.

The requested and used memory capacity may vary greatly, though servers running on VDSmanager (FreeBSD) require less this resource.

VDSmanager (FreeBSD) virtualization system searches for the application that used the maximum RAM and kills it. As a result you can start an application that is not resource intensive (you can enter shell and solve the problems).

FreeBSD vs Linux

If do not have much Linux experience, but you need operational system for hosting or mail server, You may choose a FreeBSD-based VPS. In case you have specific software not running on FreeBSD (we should note that VDSmanager supports FreeBSD-based Linux applications using the Linux-compat tool) or you need VPN connection to the server via tun interface – you should use this technology. We hope that having compared VDSmanager and OpenVZ technologies for server you will make the right decision!

How to change Operating system

Since FreeBSD and Linux based servers are hosted on different hardware platforms, it is impossible to reinstall operating systems automatically. You should order a new server with a required operating system and cancel the old one.
