Still not decided about virtualization platform for my "webhotel v2" (ns, mail, web servers, etc.).
KVM would be a natural way to go, I suppose, only it is too bad CentOS 6 will not be out in time for me - I guess KVM would be more mature in CentOS 6.
Any experience with the free "VMware vSphere Hypervisor"?. (It was formerly known as "VMware ESXi Single Server" or "free ESXi".)

I would need a tutorial about that... For example, does that run without a host OS? Can it be managed only via Win clients? Issues with CentOS 4/5 guests (all my systems are currently CentOS 4/5).
I'm currently using Ubuntu Server 10.04-LTS as a host for KVM running CentOS5.5 guests I migrated from VMware Server 2. Works fine. A nice feature of current generation KVM is that you are supposed to be able to do live migration even without shared storage (although I haven't tested that yet). I wrote some custom scripts to allow me to take LVM snapshots for whole-image backups and I'm pretty happy with the who setup.
The only corners I encountered were
1) A lack of documentation on how to configure bridging over bonded interfaces for the host server. It turned out to be fairly easy - just not clearly documented anyplace I could find.
2) The default configuration for rebooting/shutting dow the host server just 'shoots the guests in the head' rather than having them shutdown cleanly. :( You will want to write something to make sure they get shutdown properly instead.
