If you do brctl show i suspect em2 is not being added to the bridge. You could also manually add it to the bridge: brctl addif br100 em2 Also the private ip address is not added to the bridge. if you do: brctl show br100 you will see that each vm gets a vnet* device that is added to the bridge. The ip only exists internally to the vm. > fixed_range = 192.168.9.32/27 > flat_network_dhcp_start = 192.168.9.33 > connection_type = libvirt > flat_injected = False > multi_host = True > flat_network_dns = <public_ip> > flat_network_bridge = br100 > > first machine have > eth0 = public ip > eth1 = 192.168.9.1 > > second machine > em1 = public ip > em2 = 192.168.9.2 > > > I am creating nova network like this > nova-manage network create private --fixed_range_v4=192.168.9.32/27 > --num_network=1 --bridge=br100 --network_size=32 --multi_host=True > > > Can some one suggest some thing. > > Thanks > Kashif > > > _______________________________________________ > Mailing list: https://launchpad.net/~openstack > Post to : openstack@lists.launchpad.net > Unsubscribe : https://launchpad.net/~openstack > More help : https://help.launchpad.net/ListHelp
