Create /etc/sysconfig/network-scripts/ifcfg-virbr10 with these contents:

DEVICE=virbr10

# Change to 'no' to disable NetworkManager for this interface.
NM_CONTROLLED=yes
ONBOOT=yes

NETMASK=255.255.255.248

IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6ADDR=2001:db8:aa::1

If using NetworkManager:

# nmcli connection load /etc/sysconfig/network-scripts/ifcfg-virbr10
# nmcli connection up virbr10

If using NetworkManager on Red Hat Enterprise Linux 6:

# echo "NM_BOND_BRIDGE_VLAN_ENABLED=yes" >> /etc/sysconfig/network
# service NetworkManager restart

If not using NetworkManager:

# ifup virbr10
# ifup virbr10-dummy
