You need to go *straight* to VMWare. Do not stop at Xen, do not stop

Why should the better choice be ESX than KVM for somebody who is familiar
with Linux?
Seriously, I am building my first server for virtualisation and KVM works
out of the box /two days ;-) /.
Becasue libvirt was designed by goats who'd been sniffing too many
pheromones. Let's just say that they were not paying attention to Eric
Raymond's guidelines on open source GUI's
(http://www.catb.org/~esr/writings/cups-horror.html) and leave it at
that.
Our favorite upstream vendor is usually quite good at writing gui's,
having learned a lot of lessons over the years and having strong
developers. libvirt is not one of their shining efforts.
It looks like you complain about GUI tools, which are provided with
libvirt (it is a library). Honestly, I expected some technical things
KVM versus ESX. I don't think, that the GUI is a major problem, it is a
matter of personal taste. I have no problem with the default GUI
interface and I enjoy using Python's libvirt bindings in scripts.
VMWare, especially its LabManager suite with which I've worked
recently, does a much more thorough job. It's not perfect: the update
of VMwareTools with kernel updates is hardly perfect, and its
interactions with the NetworkManager of SL 6 and RHEL 6 are not good.
But I'm not thrilled with NetworkManager in servers or managed
environments, either.
Well, may be for static servers, using laptops without NetworkManager
would be pain.
I've heard good things about KVM performance, but didn't see it in
RHEL/CentOS/SL 5.x. I'll be very intersted to see the results of the
Debian testing I'm doing in the near future.
I use 6.x KVM and performance is really good. Debian? My experience is
that almost all things being developed by Red Had, are much worse
integrated in Debian [Lenny|Squeeze]: SELinux, Network Manager, Package
Kit, KVM ...
