It's not just Xen, either - we have a messaging queue product running on several Linux servers here.  I was surprised to find out that the messaging software - a java app, keep in mind - was running on a host (Virtual Machine) with 256 MB RAM allocated to it!

A CentOS server running a java-based enterprise messaging queue processing production traffic - all on 256 MB RAM.

My head is spinning.  I got an old Pentium III workstation
that barely ran Windows XP and thought I'd try installing
some cloud software on it just to see what it looks like.

I've already installed the cloud management software, and
as part of the configuration, they say to create and run
a xen virtual machine to verify that xen is properly installed.

That's where I'm at.  I'm installing the latest version of
CentOS on a headless VM that is installed on a headless
workstation with less than a gig of ram.  And it's working.
It simply amazes me how well Linux and xen can manage
resources!
