About OpenVZ Software
What is OpenVZ
OpenVZ is a complete server automation and virtualization solution developed by SWsoft.
OpenVZ creates multiple isolated Virtual Private Servers (VPSs) on a single physical server to
share hardware and management effort with maximum efficiency. Each VPS performs and
executes exactly like a stand-alone server for its users and applications as it can be rebooted
independently and has its own
root
access, users, IP addresses, memory, processes, files,
applications, system libraries, and configuration files. Light overhead and efficient design of
OpenVZ makes it the right virtualization choice for production servers with live applications
and real-life data.
The basic OpenVZ VPS capabilities are:
Dynamic Real-time Partitioning
– Partition a physical server into tens of VPSs, each with
full dedicated server functionality.
Resource Management
– Assign and control VPS resource parameters and re-allocate
resources in real-time.
Mass Management
- Manage a multitude of physical servers and Virtual Private Servers in a
unified way.
