The following page describes the steps to manually add a new Ethernet bridge (<code>vmbrX</code>) to an existing stoney cloud installation.
Before:
<pre>
+----------------+----------------+----------------+----------------+
IP interfaces | 192.168.140.1X | 10.1.110.1X | 10.1.120.1X | 10.1.130.1X |
+----------------+----------------+----------------+----------------+
+----------------+----------------+----------------+----------------+
Bridging interfaces | vmbr0 | vmbr1 | vmbr2 | vmbr3 |
+----------------+----------------+----------------+----------------+
+----------------+----------------+----------------+----------------+
VLAN interfaces | vlan140 | vlan110 | vlan120 | vlan130 |
+----------------+----------------+----------------+----------------+
+-------------------------------------------------------------------+
Bonding interfaces | bond0 (bonding.mode=802.3ad) |
+-------------------------------------------------------------------+
+----------------+----------------+----------------+----------------+
Physical interfaces | eth0 | eth1 | eth2 | ethN |
+----------------+----------------+----------------+----------------+
</pre>
After adding an additional bridge (vmbr4):
<pre>
+----------------+----------------+----------------+----------------+----------------+
IP interfaces | 192.168.140.1X | 10.1.110.1X | 10.1.120.1X | 10.1.130.1X | 192.168.141.1X |
+----------------+----------------+----------------+----------------+----------------+
+----------------+----------------+----------------+----------------+----------------+
Bridging interfaces | vmbr0 | (vmbr1) | (vmbr2) | (vmbr3) | vmbr4 |
+----------------+----------------+----------------+----------------+----------------+
+----------------+----------------+----------------+----------------+----------------+
VLAN interfaces | vlan140 | vlan110 | vlan120 | vlan130 | vlan141 |
+----------------+----------------+----------------+----------------+----------------+
+------------------------------------------------------------------------------------+
Bonding interfaces | bond0 (bonding.mode=802.3ad) |
+------------------------------------------------------------------------------------+
+----------------+----------------+----------------+---------------------------------+
Physical interfaces | eth0 | eth1 | eth2 | ethN |
+----------------+----------------+----------------+---------------------------------+
