Message #12672
Can't ping instances in remote node .
Hi, all.
I have two nodes
installation.
Server1 runs all the components of Nova, Glance,Keystone and Horizon
(OpenStack Dashboard). Server2 runs only nova-compute.
I am using FlatDHCP
mode with a single network interface per
node.
network config :
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.2.70.106
netmask 255.255.255.0
network 10.2.70.0
broadcast 10.2.70.255
gateway 10.2.70.1
dns-nameservers 10.3.10.151
auto br100
iface br100 inet static
address 192.168.3.1
netmask 255.255.255.0
bridge_stp off
bridge_fd 0
Alter I assigned
floating ip to instances , I can ping to instances which running on server 1
but I do it with instances are running
on server 2.
