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.

Xen allows one to create fully virtualized virtual machines via hardware virtualization and para-virtualized "Xen" machines.
In this regard it is probably more functional then Zones and if the PV machines are properly designed it should be more reliable.
I think Sun released a Xen PV enabled version of the Solaris kernel recently, so you could run Zones in a Solaris PV under Xen, if you were so inclined...

you might want to take a look at the openvz project, its one of many userspace only partitioning systems around on Linux these days.
they natively support CentOS4 and maybe even CentOS5

We are using openvz at work, and is a excellent alternative to full blown virtualization.
we have install now under centos4 and centos5 for example for dev groups that have dedicated environments. openvz will provide tools and kernels for both ones. The only "problem" that have is not full support for x86_64 system. but we have solved this problem (thanks to the openvz wiki) and have servers with centos4 and centos5 VE (virtual environments).
we are prefering openvz over xen in centos5 install in almost all the installs. The only diference is when we have a need to full virt (like running rh7/rh8 inside a xen domain)
