My server at home has a single NIC that I put into a bridge. From my
/etc/network/interfaces file (this is a Debian and related file, you will
need to figure out how to apply this to a CentOS server):
auto br0
iface br0 inet static
address XX.XX.XX.XX
netmask 255.255.255.0
network XX.XX.XX.0
broadcast XX.XX.XX.255
gateway XX.XX.XX.3
dns-nameservers 127.0.0.1 XX.XX.XX.8 XX.XX.XX.3
dns-search domaina.tld domainb.tld
bridge_ports eth0
bridge_stp off
bridge_fd 0
bridge_maxwait 0
KVM simply uses br0 as the network device while the host retains
connectivity. For a production server you really want VM traffic on a
different NIC.
This config also works for IPv6. My host and VMs all have IPv6
connectivity without having to change any configuration client (or KVM
host) side.
