Not sure what I am missing by not including Xen but I am pretty new at it.
CentOS 5 predates KVM and used Xen for virtualization. CentOS 6 and 7 include
KVM for virtualization and don't use a Xen hypervisor. You are not 'missing'
anything: Xen is just the older virtualization hypervisor.
That is what I suspected. Thanks to the reassurance.
I can not help but believe that CentOS 7 would be a better platform for
virtualization than CentOS 5.
CentOS 7 is not too bad but it is different and it has taken me a while
to stop fighting it.
I don't want to take that step until I have learned to deal with the likes of
systemd, etc. I install CentOS 6 as the host and install CentOS 7 in a VM, to
have a standbox to learn in, and still be able to get work done.
Sounds like a good plan.
I just jumped in with a couple of spare physical machines to see if I
could get Centos 7 to production quality/use in key roles.
I was able to build the systems and test them with the ability to drop
the old system back in if it did not work.
The changes to networking and the firewall were hard to absorb. The new
way to manage processes is still a bit of a challenge for me but I am
not spending any time on this since it works just fine.
I run a software firewall, DNS server and virtual router which I moved
from CentOS 4 to CentOS 7 and it seems to work better but it is hard to
tell if it is the newer hardware or the new OS. This is a critical part
of the infrastructure and I am happy with the change.
The hardware was too old to run the nouveau driver properly so I am
running the NVIDIA legacy driver. Works but I am not using it as a
workstation.

Did I miss the discussion about the drivers from NVIDIA? I am using them
with new and old hardware(different machines).
A bit tricky to get working and there are different drivers for legacy
cards and newer cards.
The drivers from NVIDIA are not supported for Xen-based systems. I am using
Xen for virtualization, so the drivers from NVIDIA are not an option.
Appearently the kernel and Xorg that sh
I had trouble with the nouveau driver but it may have been me or may
have been an early version.
The nouveau driver is not available for CentOS 5 -- the kernel and Xorg
libraries are too old.
CentOS 7 runs well but it does have a lot of changes to the tools that
one got used to in CentOS 5 and 6.
*I* am not ready for that big a change. It would probably be too disruptive
for my work flow. I *may* install CentOS 7 as a VM at some point.
It is supposed to be a better workstation OS.
I am still running 5 and 6 on some production machines.
I am not using my units as workstations but like to have the GUI working
well in case I have some maintenance activities that are easier in the GUI.

Not without a price. What you have is hardware technology that is more
advanced than the foundation on which that support is built. A GeForce 8200
needs either the FOSS nouveau driver, which seems to be missing from CentOS
5, or the proprietary NVidia driver. VESA is a low technology fallback driver
wholly incapable of properly supporting widescreen displays. AFAICT, there's
no amount of xorg.conf or xrandr twiddling you can do to overcome the
shortcomings of a fallback driver.
The video chipset has been working fine with the CentOS software, with a 4:3
monitor. The (available) proprietary NVidia driver won't work with a Xen
kernel.
The graphics card BIOS contains the modes that vesa can use. It doesn't have
widescreen modes in it. The below 3 choices are yours.
CentOS6 should drive things better in theory.
I guess I will have to upgade to CentOS 6...
Dave.
*I* have better things to do than
spend all of my time dealing with incompatible updates every few months.
You have 3 choices that I can see:
1-upgrade software to the technology level of your hardware (nouveau driver,
likely requiring KMS kernel)
2-backlevel your video hardware (either supported gfxcard, or supported 4:3
or 5:4 aspect display)
3-suffer a standard aspect video mode on your widescreen display
