im trying to setup up a 3 node openstack cloud as in the document of ubuntu 14.04 LTS. im using a vmware workstation 9, with windows 8 as the host os. i have setup everything n its pinging fine(all the node ping each other and windows pings the managment node too). my question is that

1 i cant ping the  floation ip i created ?
2 due to this i cant create instance, the creation shows spawning
3 i done know if my vmware is in promescuious mode or no.
->i skipped this external network creation part :
The external network interface
auto INTERFACE_NAME
iface INTERFACE_NAME inet manual
        up ip link set dev $IFACE up
        down ip link set dev $IFACE down
i had replaced INTERFACE_NAME with eth0(my nat connection on vmware).
->after creating a br-ex, internet connection doesnt work.

i have been searching for the solution for a long time, anyone pointing the right direction would be a great help.thanks in advance
