```
The cloudstack work node is using KVM + openvswitch
(http://docs.cloudstack.apache.org/en/latest/installguide/hypervisor/kvm.html#configuring-the-network-bridges-for-openvswitch
)
##### The configuration:
```
ovs-vsctl add-br cloudbr
ovs-vsctl add-port cloudbr eno1
ovs-vsctl set port cloudbr trunks=136,291,300
ovs-vsctl add-br mgmt0 cloudbr 136
ovs-vsctl add-br cloudbr0 cloudbr 291
ovs-vsctl add-br cloudbr1 cloudbr 300
```
The network configuration:
ifcfg-eno1
```
TYPE=OVSPort
IPV6INIT=no
BOOTPROTO=none
DEVICETYPE=ovs
OVS_BRIDGE=cloudbr
UUID=22c22720-553e-4c78-9f8a-5873805a0842
HOTPLUG=no
DEVICE=eno1
ONBOOT=yes
```
ifcfg-cloudbr
```
DEVICE=cloudbr
TYPE=OVSBridge
ONBOOT=yes
HOTPLUG=no
BOOTPROT=none
DEVICETYPE=ovs
```
ifcfg-mgmt0
```
DEVICE=mgmt0
TYPE=OVSBridge
ONBOOT=yes
HOTPLUG=no
BOOTPROT=static
DEVICETYPE=ovs
IPADDR=10.67.36.200
NETMASK=255.255.252.0
GATEWAY=10.67.39.254
```
ifcfg-cloudbr0
```
DEVICE=cloudbr0
ONBOOT=yes
HOTPLUG=no
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROT=none
```
ifcfg-cloudbr1
```
DEVICE=cloudbr1
ONBOOT=yes
HOTPLUG=no
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROT=none
```
The result:
