Hi Lars,

I am using Proxmox. It is based on Debian. It is a bare metal installer, 
like ESX. You manage your VMs from a web interface. You can live migrate 
your VMs from one node to another if you use a central storage or DRDB.
The bare metal installer takes care of all the initial configuration 
(bridge, LVM for snapshot...).

I wait to see what will do RHEVM, but at this time, I am not aware of 
such a convenient solution under RHEL/CentOS...
