I don't think you will really need Open vSwitch if your only goal is to do
server virtualization. If you are interested in the following features
though, Open vSwitch will be a good choice.

Since you would be using KVM as your hypervisor, you can look up libvirt
integration with OVS. It is quite straight-forward.

I think one has to atleast understand tap devices, o/p of tcpdump,
protocols like ARP, ICMP etc to do any meaningful debugging.
There is documentation about openvswitch here:
