[ovirt-users] Network issues with my node

[Andy Michielsen]

Hello,

I'm having network issues with my node. I can run virtual machines fine and
my ovirt-engine can function with my node. But I'm unable to connect to the
internet to get the updates.

On my node I have 2 physical nic's, one I use for the VM's and the other
one I use for the ovirtmgmt.
On the node I have installed a centos 6.5 Minimal install and started with
just one nic for vm's and ovirtmgmt. At that time I could stil do updates.

This is the output for ifconfig

This is my first nic

[root at romulus network-scripts]# cat ifcfg-em1
# Generated by VDSM version 4.13.3-4.el6
DEVICE=em1
ONBOOT=yes
HWADDR=90:b1:1c:41:8f:e6
BRIDGE=ovirtmgmt
NM_CONTROLLED=no
STP=no

And my second one

[root at romulus network-scripts]# cat ifcfg-em2
# Generated by VDSM version 4.13.3-4.el6
DEVICE=em2
ONBOOT=yes
HWADDR=90:b1:1c:41:8f:e7
BRIDGE=VM
NM_CONTROLLED=no
STP=no

my ovirtmgmt setup is

[root at romulus network-scripts]# cat ifcfg-ovirtmgmt
# Generated by VDSM version 4.13.3-4.el6
DEVICE=ovirtmgmt
ONBOOT=yes
TYPE=Bridge
DELAY=0
IPADDR=192.168.203.150
NETMASK=255.255.255.0
GATEWAY=192.168.203.98
DNS1=192.168.204.2
DNS2=192.168.204.218
BOOTPROTO=none
DEFROUTE=yes
NM_CONTROLLED=no
STP=no

for my VM

[root at romulus network-scripts]# cat ifcfg-VM
# Generated by VDSM version 4.13.3-4.el6
DEVICE=VM
ONBOOT=yes
TYPE=Bridge
DELAY=0
DEFROUTE=no
NM_CONTROLLED=no
STP=no

Where do I need to configure my DNS servers ?

Kind regards.
