I just wondered if there was an equivalent to Solaris Zones available for Linux. Not necessarily a full blown separate operating system like vmware, but more like chroot on steroids...
There are quite a few similar products, but from what I read about Solaris Zones, it is more like Zen or VMWare that just chroot.
Zones uses one system-wide Solaris kernel, its only userspace and devices and such that are virtualized. It does create per zone network devices, as well as security.
OpenVZ is what you are looking for. Short summary:
- only one kernel shared between host and guests (lower overhead) - memory and VFS cache can be shared (huge memory win) - easy to setup and manage
There are some drawbacks as well because of the characteristics. But depending on what you want to do, OpenVZ can be useful.
