There are different kinds of virtualization. OS-level virtualization like Linux-VServer and FreeBSD jails have little to no overhead while being very secure.

- tptacek 16y agoJails aren't virtualization. I don't know why they don't use jails, but the answer on "virtualization" seems straightforward.
- martinp 16y agoYes, I was surprised too. I've never used the word "virtualization" when refering to jails and VServer, but Wikipedia apparently refers to it as "Operating system-level virtualization". http://en.wikipedia.org/wiki/OS-level_virtualization http://en.wikipedia.org/wiki/OS-level_virtualization
