It's Windows only for the management piece because it is written in
.NET, and yes it is the same for RHEV (Red Hat's Virtualization
server).  I don't know why it has to be in .NET, but it is (Probably a
C# thing).


For my money, and as this is a CentOS mailing list please forgive the
following recommendations, I would go with Oracle VM...because I don't
have much money.  OVM is free to download but has paid support
options.  It's a really small implementation of RHEL using the Xen
kernel and has a Non-Windows management UI.  It supports clustering
and high-availability with OCFS2 and does para and full
virtualization.

If I had more of a budget, I would go with RHEV.  It costs a lot less
to run compared to ESX and Hyper-V, and is higher performing too.
This, of course, uses KVM and not Xen, but the performance is there.
You need RHEL 5.4 and hardware compatibility. I'm not sure if you
would be able to manage CentOS 5.4 hosts with RHEV, but it'd be worth
a try.  I don't see why it wouldn't work.
