Thx, for the suggestions!
So if I use FlatManager how can I create the network correct in order
for the instance to get an IP from a DHCP Server that I am running??? Is
the following correct and sufficient??
CONTROLLER NODE
---------------
nova network-create vmnet --fixed-range-v4=X.X.X.128/25
--bridge-interface=br100 --multi-host=T
I understand that I have to change these two lines that you suggest on
the nova.conf file and then probably reboot the machine. Should I change
it at both the CONTROLLER and the COMPUTE nodes or just in one of them
and which???
Best,
G.

Dear Dimitri and all,
do you define the static IP for br100 somewhere or not???
Yes, in my case it's in
/etc/sysconfig/[network-scripts,networking/devices,networking/profiles/default]/ifcfg-br100
(it's the same file hardlinked from 3 places). (I am not sure if
that's
the "proper redhat-6 way" of doing this, my configs got copied from
centos 5.) The same way you have it:
# cat /etc/sysconfig/network-scripts/ifcfg-br100
...
IPADDR=X.X.X.210
...
I can ping the X.X.X.210 but that is because the br100 has static IP
X.X.X.210 and if I flush the iptables I can login to the already
available node and NOT at the CirrOS instance that should have the
X.X.X.210 IP.
Ah, OK. No, the instance should not have the .210 ip. If you're using
the default network manager (Flat+DHCP) you should define the
10.0.0.0
network, restart it all and then log on to your cirros instance via
vnc
and see what ifconfig -a says. It should have an ip in 10.0.0.x
range,
then you can continue troubleshooting from there.
If you want your instances to be in the same X.X.X.X subnet as the
br100, you'll need in your nova.conf
network_manager = nova.network.manager.FlatManager
firewall_driver = nova.virt.firewall.NoopFirewallDriver
and then restart it all, then log on to your cirros instance via vnc
and
give it a fixed ip -- not .210 -- or if you have a dhcp server on the
X.X.X.X subnet the instance should get its ip from there.
