	I have to concur with this.  If it's Linux on Linux, this is, IMNSHO,
the way to go.  It's very light weight.  I've got almost 3 dozens VM's
running on one host node with almost 800 processes without freaking the
load average out.  With vzmigrate, you can move a machine from one chunk
of iron to the other as demand dictates.  OpenVZ is the OpenSource side
of the Virtuoso product, so if you want to go with something
"commercial", you've got that to back you up and they've got some pretty
tools to work with.  I've made a few minor contributions to the OpenVZ
project myself.

	One little caveat to the comments here.  The contributions from the
OpenVZ gang into the mainline kernel are for the LXC Linux Containers.
The Linux Vserver group (a similar parallel group) are making similar
contributions and are participating.  One would argue that they are both
working themselves out of a job.  The LXC containers will be the
mainline inheritor of those projects.  This will be the Linux equivalent
of Solaris Zones and BSD Gaols/Jails.   You can make it work now but
it's not plug and play quite yet, so I'm sticking with OpenVZ till LXC
is ready for prime time.
