Hello,
i have a question about adding a second Nic. After adding a second one
the WebGUI and oVirt is very slow. The situation is as follow. Each nic
has its own network and are seperated from each other. nic1 -
192.168.0.x for internal and nic2 192.168.1.x through the wan. if i use
trace from the client i call the WebGUI, it goes over 192.168.0.x, the
right way. but if i trace the engine self on localhost with its hostname
it goes over 192.168.1.x, the wrong way and takes longer.
i am not sure if its an ovirt problem or from hostsystem centos, but i
didnt find any solution.
# ip route show
default via 192.168.0.3 dev ovirtmgmt
default via 192.168.1.1 dev enp0s29u1u2c2 proto static metric 100
169.254.0.0/16 dev ovirtmgmt scope link metric 1006
192.168.0.0/24 dev ovirtmgmt proto kernel scope link src
192.168.0.153
192.168.1.0/24 dev enp0s29u1u2c2 proto kernel scope link src
192.168.1.2 metric 100
thx for help

It seems you have 2 default gw set.
If you don't use networkmanager, and nic1 is the right adapter to use as
default gateway, put
DEFROUTE=no
Inside ifcfg-enp0s29u1u2c2 in /etc/sysconfig/network-scripts and restart
9:45 a.m.
Most likely (we've had something like that in FOSDEM) issue with DNS
resolving.
Make sure all IP addresses are correctly resolved.

Hello,
i simply add the nic and i think CentOS configure these by itself. Ok, i
can change that. Short to my intentions. I want to use nic1 for my lan
and nic2 for the wan route into the internet. in ovirt i want to install
a firewall and configure both nics, nic for lan and nic2 for wan. in the
other vm's i want to install only nic1 as bridge and configure the
firwall as gateway which also service the dhcp. at all it must be safe
that the vms cant break out of this and go around the firewall. so as i
understand i would do this:
- set in centos nic1 as default gatway wich has 192.168.0.1 as gateway
- set in centos nic2 without default route
- add in ovirt a new network / nic
- create the vm for the firwall and assign nic1 and nic2
- in the other vms i would only assign nic1
is that the way to do or what do you think?
thx
