I'm wondering what people recommend for virtual servers these days?
CentOS 4 with a vserver kernel?  Wait for CentOS 5 and use Xen?  VMware?
(Vmware is the heavy solution, but it does mean I could host a windows
session if I wanted to).  Or Solaris 10 and zones?
    

Personally I'm using VMWare-workstation, but it isn't an ideal solution:
- it costs
- it is hard to make VMs start at system boot
- it is a heavyweight solution

  

ESX is a "lighter-weight" solution (in that it runs on the bare-metal rather than requiring a host OS that sucks up resources.  It of course is the most expensive solution but IMHO, it's worth every penny.  ESX is the only virtualization option I would care to put production workloads on.

The reason I am using -Workstatin as opposed to the free -Server
offering is because -Server does not provide some virtual hardware
that is useful in a workstation environment.  

I find it odd what drives your requirements in the end.  In my
particular case, I am connecting to a Windows VM through a Sun Ray
session, and found my Windows VMs were less usefull without the sound
devices because Windows Movie Maker would not start on a system which
lacked a sound card.  (And I wanted Windows Movie Maker to convert
video streams from the high-bitrate that comes from the camera down
to something a little more portable, not to actually view anything.)
  

VMWare Server can do sound, it's just that the default virtual machine doesn't include a sound card.  Just go to the settings for the VM, add new hardware and add a sound card.  Still Workstation does a number of handy things that Server doesn't, multiple snapshots for instance...
