Help with host network config KVM + Centos
Hi all,
I have a single centOS 6.4 KVM host with two NICs
eth0: 192.168.100.131/24 GW 192.168.100.254 is for public access (internet access)
eth1: 10.3.9.50/8 no GW is for management access
Could someone please help me with the initial configuration to work with KVM and Cloudstack?
This setup is different than the documentation.
Thank you for your help in advance!

Hi Sanjeev,
I followed this configuration on my CS + KVM + Openvswitch. Host was added
correctly, System VMs started but can't be ping or ssh. Does this
configuration work on your setup?

Thank you very much for this.
Are you using openvswitch for this config?

Hi,
You need to configure two bridges say cloudbr0 and cloudbr1 using the two interfaces present on the KVM host.
Use these bridge names as traffic labels in the Physical Network you create during zone creation in CloudStack.
Eg. If cloudbr0 is on eth0 and cloudbr1 is on eth1 then use cloudbr0 as traffic lable for guest and public traffic and cloudbr1 for management traffic.
Following configuration might help you in configuring bridges:
Configure network interfaces:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
IPV6INIT=no
NM_CONTROLLED=no
ONBOOT=yes
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=cloudbr0
/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
IPV6INIT=no
NM_CONTROLLED=no
ONBOOT=yes
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=cloudbr1
/etc/sysconfig/network-scripts/ifcfg-cloudbr0
DEVICE=cloudbr0
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=172.16.10.10
GATEWAY=172.16.10.1

HOTPLUG=no
/etc/sysconfig/network-scripts/ifcfg-cloudbr1
DEVICE=cloudbr1
ONBOOT=yes

BOOTPROTO=none
HOTPLUG=no
Thanks,
Sanjeev

Re: Help with host network config KVM + Centos

Open vSwitch is not required. For this configuration I don't think any
special configuration is required on the host or in CloudStack. Try
simply adding the host. CloudStack should detect the default gateway on
eth0 and create the necessary bridge on it. All traffic types will use
that bridge by default.
My main concern is if CloudStack will work with the multi-homed
configuration. If after adding the host you find that the CPVM is not
working, it may be trying and failing to connect to 10.3.9.50, so you
may need to explicitly configure management traffic to use eth1. This
is done by creating a bridge on eth1 and updating the traffic label in
CloudStack.
Best regards,
Kirk

This is what I was trying to do without success as well.

Jake,
Are you trying to just get something up and running, or do you specifically want to divide traffic up in a certain way? If the former, I believe I was able to set my hosts up with just the bridge setup pointing at eth0 without any sort of VLANs. It was either that, or without special setup of any kind.
Thanks, Dave

Hi all,
I have a single centOS 6.4 KVM host with two NICs
eth0: 192.168.100.131/24 GW 192.168.100.254 is for public access (internet access)

This setup is different than the documentation. I do not want to use openvswitch if possible.
Thank you for your help in advance!
