Virtuozzo virtualization environment allows the host operating system level but not at the hardware level often
make other virtualization systems.

All VPS restart the operating system kernel. A virtual environment can provide the nucleus of a wide range of operating systems, in particular, of course, from the side of the applications launched, users, network services
. Based on openvz Virtuozzo technology.

similar systems are Solaris Containers virtualization, Linux – vserver, FreeBSD jail.

As virtualization is the operating system, is that a larger number of virtual servers possible. It’s called hype.

Virtuozzo supports 64 – processor servers with 64 GB of memory.

Available in Virtuozzo VPS’s possible transfer to another server significantly reduces system downtime
on hardware upgrades. Just connect a new physical server and move all VPS.
The system closes a few seconds.

Despite the limitations of the beginning of a single operating system on a host, can Virtuozzo restart various Linux distributions. VPS explained that began in a host, has its own library system,
configuration files and programs.
