I am just using the KVM included in CentOS7 with Cloudstack.
Not sure what I am missing by not including Xen but I am pretty new at it.
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.
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
