Solaris has had this (zones/containers) for about 4 years now and it works well for a certain class of issues. I do wish though that they would have copied the Solaris way of doing it - under Solaris there is only zonecfg for configuring a zone, with a simple file format for describing a zone; and zoneadm which lets you list, stop, start, etc. an already-configured zone. It is kind of funny, in that Sun is using Xen more now, while Linux has had Xen already and is now doing stuff with containers.
