Virtuozzo commercial software.
Open source container-based virtualization for Linux.
Multiple secure, isolated Linux containers (otherwise known as VEs or VPSs)
on a single physical server enabling better server utilization and ensuring
that applications do not conflict.
Each container performs and executes exactly like a stand-alone server; a container can be rebooted
independently and have root access, users, IP addresses, memory, processes, files, applications,
system libraries and configuration files.
