Virtualize anything and everything?

Question

Virtualization

Recently I caught myself thinking that I'm trying to drive everything into virtual machines stuffed into different raids, is this correct? At the moment there are such virtual machines (separated by a comma): 1C-server, dc1, dc2, gateway, small server for small needs (jabber, ksc). I also plan to virtualize asterisk. Is this adequate or excessive?

It would be a good idea to move the virtual DC2 to another hypervisor. Several controllers are made so that the failure of one does not disrupt the operation of the domain.
